Submitted December 1 994 Abstract This thesis reviews the history of the semiconductor industry during the period 1950 to 1985 and identifies the major factors governing its development. It also analyses the rea- sons for the failure of British manufacturing companies to develop on a more competitive scale. The development of the British semiconductor industry, almost from the start, took place within an environment dominated by large foreign multinational companies. Operat- ing under conditions of technical lag and with increasing penetration of its markets, it con- centrated, aided by funding from the Ministry of Defence, on producing specialised solid-state components for the much smaller military market. Because of its size, this mar- ket was not sufficiently large to initiate the pump-priming action which was such an im- portant feature in bringing about the success of its American counterpart. Generous Government inducements, aimed at attracting multinational companies to British shores, did little to assist the development of the indigenous industry, which, un- derfunded, underprotected and increasingly restricted to niche markets by competitors, soon fell into relative decline. Direct Governmental assistance to the ailing commercial sector of the British semiconductor industry came too late substantially to affect the situa- tion. Both inconsistency and lack of continuity in policy towards the industry, under suc- cessive Governments, did not improve the confidence of industrial management, nor encourage a more long-term outlook. It is argued within this thesis that the best chance of industrial success would have been to adopt a national policy towards the industry at an early stage, with substantial funding on a long-term basis, together with adequate import controls. The epilogue concludes that only within a European framework might it now be possible to build a semiconductor manufacturing industry, eventually capable of competing on equal terms with overseas ri- vals. 1 Acknowledgements First and foremost, I would like to thank my three supervisors, Prof. R.A. Buchanan, Dr. D. Gorham and Dr. G.R. Roberts for their advice, encouragement, and support throughout this research project. Because of its nature, this work has relied, to a considerable extent, upon a wide range of information obtained through interviews with those in Government, industry and uni- versity departments. Almost all of those approached were extremely helpful, friendly and informative. This fact undoubtedly lightened my task and added to the enjoyment of the work. Some extent of my indebtedness may be obtained from a glance at the lengthy list of names of those who have assisted me and which I have included as an appendix. More generally, although also importantly, I am indebted to my ex. colleagues for the numerous and often rewarding conversations held through the years, when employed as a semiconductor engineer within the industry. Although it is impossible to properly evaluate their influence, there can be little doubt that my views regarding the industry have been, at the very least, strongly stimulated and tested by their opinions. Last but not least, I would also like to thank my daughter, Siani, for her welcome assis- tance in arranging the printing of the final version of this thesis. In order to conform to Open University regulations concerning previously published work, attention is drawn to the fact that some material contained within chapters 5 & 6 of this thesis has already been published under the title "The role of the Ministry of Defence (MOD) in influencing the commercial performance of the British semiconductor indus- try", History and Technology Vol.11, (1994), pp. 18 1-193. 11 Contents Page Abstract 1 Acknowledgements 11 Table of Contents 111 List of Tables vii Chapter 1 Introduction The Importance of Microelectronics 1 Introductory Theoretical Framework 2 Previous Contributions to the History of Semiconductor Manufacture: a Brief Survey 9 References 18 Chapter 2 A Review of the General Characteristics of the British Thermionic Valve Industry Introduction 21 The Development of the Thermionic Valve: The Initial Phase 1906-20 21 Development of the Valve Industry During the Inter-War Period 26 The UK Valve Manufacturing Industry in World War Two 36 Post-War Developments 41 Economies of Scale in Valve Manufacture 43 The Influence of Mullard Ltd upon Post-War Valve Manufacture 44 Cathode-ray Tube Production 47 Tube Sales and Import/Export Figures 48 Some Factors Affecting the Development of the Industry 50 Valve Manufacture within the United States 53 The Role of Patents 55 References 56 Chapter 3 Aspects of Early Semiconductor Development in the UK and USA Introduction 60 Genesis of the Transistor 60 Transistors versus Valves 66 Replacement of the Thermionic Valve by the Transistor 68 Aspects of Early (Germanium) Transistor Development 70 The Impetus of Military Involvement: Development of the Silicon Transistor 73 Transistor and Integrated Circuit Development 75 Product Innovation and Technical Lag 80 The British Contribution to Semiconductor Device Innovation 85 Infrastructural Factors Contributing to Technical Lag 86 111 Page The Nature of Semiconductor Development and its Contribution to Technical Lag 91 References 93 Chapter 4 Direct Governmental Involvement within the Semiconductor Manufacturing Industry Introduction 97 The Structure of Governmental Industrial Assistance - a Brief Chronological Survey 97 Governmental Policy - Organisations and Attitudes 102 Non-Defence Government Support Policy 109 INMOS 116 The Microelectronics Programme: Support within a Hostile Environment 120 Commercial Exploitation of Defence Contracts 125 Factors Involving Government Policies Directly Inhibiting Industrial Performance 127 Government Funding: A Conflict of Aims?

  • Technical Details of the Elliott 152 and 153
    Appendix 1 Technical Details of the Elliott 152 and 153 Introduction The Elliott 152 computer was part of the Admiralty’s MRS5 (medium range system 5) naval gunnery project, described in Chap. 2. The Elliott 153 computer, also known as the D/F (direction-finding) computer, was built for GCHQ and the Admiralty as described in Chap. 3. The information in this appendix is intended to supplement the overall descriptions of the machines as given in Chaps. 2 and 3. A1.1 The Elliott 152 Work on the MRS5 contract at Borehamwood began in October 1946 and was essen- tially finished in 1950. Novel target-tracking radar was at the heart of the project, the radar being synchronized to the computer’s clock. In his enthusiasm for perfecting the radar technology, John Coales seems to have spent little time on what we would now call an overall systems design. When Harry Carpenter joined the staff of the Computing Division at Borehamwood on 1 January 1949, he recalls that nobody had yet defined the way in which the control program, running on the 152 computer, would interface with guns and radar. Furthermore, nobody yet appeared to be working on the computational algorithms necessary for three-dimensional trajectory predic- tion. As for the guns that the MRS5 system was intended to control, not even the basic ballistics parameters seemed to be known with any accuracy at Borehamwood [1, 2]. A1.1.1 Communication and Data-Rate The physical separation, between radar in the Borehamwood car park and digital computer in the laboratory, necessitated an interconnecting cable of about 150 m in length.

  • CHAIN HOME TOWER at Great Baddow - Response to Case #: 1454834
    CHAIN HOME TOWER at Great Baddow - Response to case #: 1454834 My interest in this case stems from my family history. My father Bruce Neale, later to become Chief Engineer at Marconi Radar, was an RAF Warrant Officer in WW2 and worked on CH and later precision bombing aids such as OBOE and GEE. This is how he met my mother, a WAAF Sergeant who initially monitored the CH oscilloscope traces looking for the reflections of incoming German aircraft – some signals which were probably launched from that very RAF Canewdon (now Baddow) tower! Below is the remarkable photograph of my ‘to be’ parents actually in an Oboe station in 1943 courtesy of Colin Latham’s book ‘Radar-A wartime Miracle’. I have always regarded myself as a child of Radar! The ‘CH-The First Operational Radar’ article ( www.radarpages.co.uk/mob/ch/chainhome.htm ) was written by my father for the GEC Journal, a special edition commemorating the 50th anniversary of Robert Watson Watt and Arnold Wilkins’ demonstration of the feasibility of detecting radio reflections from aircraft at Weedon, Northamptonshire in 1935. My parents got to know Arnold Wilkins and his wife towards the end of all of their lives. The article has become the reference paper for anybody interested in the CH Radar System and he gave many lectures on the subject. My father had joined the Marconi Company in the early 1950’s when they won the contract for project ROTOR to upgrade the UK WW2 Early Warning Radar Network which included the later versions of CH and he officially retired in 1985 although he continued as a consultant until his death.

  • Travels in Goneland
    Travels in Goneland Michael Prior 1 Introduction It is easy enough to see the remains of the earliest industrial revolution if one knows where to look; along the steep watercourses that powered the first mechanized mills. Now overgrown by trees and bushes, these stone basins and channels provided the -­‐ water power for the first mechanized mills with power looms and spinning frames. They also provided the spark for the first industrial labour-­‐ protests, the Luddites, mostly handloom weavers, who smashed the mechanized mills and were themselves broken on gallows in York and Manchester. Staups Mill and waterfall, Jumble Hole clough, Hebden Bridge The next stage of the industrial development based on coal also can also still be seen in the remaining chimneys of the mills and factories of northern England and the Scottish . lowlands The huge buildings of the final stages of this revolution are impossible to miss, close to the centres of Manchester, Leeds and all the northern towns and cities which sat on the coal measures. It was this which has defined Britain to this day. Travel south from Stoke, east from Leeds or north Newcastle and it is easy enough to see where the accessible coal seams ran out. Population thins out and settlements are located ural in nat places, valley bottoms along rivers rather than up hillsides where the coal seams outcropped. There are few traces left of the mines. The headworks are gone and diligent work has mostly removed or vegetated the spoil heaps f which once disfigured much o 2 the countryside. Even so, the photographic record of the mines which once covered much of Britain remains immense After the fire which shut Daw Mill in 2013, only Kellingley and Thoresby remained, both closed in 2015.

  • Chad Is Our Most Important Product
    CHAD IS OUR MOST IMPORTANT PRODUCT An Engineer’s Memoir of Teletype Corporation Jim Haynes The author operating W5YM in 1957 1 I. How it all started When I was growing up in a small town I thought it was an awfully boring place. Now I realize that I had some opportunities that probably would not have been available in a larger city. For one thing, it was possible for a kid to hang out at the newspaper office, telephone office, telegraph office, or radio station and watch a Teletype machine in operation. Things were slow enough that the people who worked there usually had time to answer questions. When I wanted to understand how a Teletype machine worked the wire chief at the telephone office let me borrow the “green book”1. After reading all about selector cams and swords and code bars and pull bars I could drop in to the Western Union office where the manager, a friend of the family, let me play with a little-used printer and see in action all the parts I had read about. Another advantage to living out in the sticks was that television arrived very late. This allowed a pretty good news stand to remain in full operation through most of my teen years. Jack’s News Stand carried several magazines of interest: Radio-Electronics, Radio & Television News, and the amateur radio magazines QST and CQ. Hugo Gernsback’s Radio-Electronics ran a series of articles by Ed- mund C. Berkeley about digital computers, which gave me an early introduction to binary arithmetic, Boolean algebra, and logic circuits.
