  • TSMC Investement in Arizona
    Michael R. Splinter Chairman of the Board Senator Robert Menendez Senator Lisa A. Murkowski Honorary Co-Chair Honorary Co-Chair Rupert J. Hammond-Chambers President INTERNAL COMMENTARY: THE STRATEGIC IMPORTANCE OF THE TSMC ARIZONA INVESTMENT MAY 15, 2020 RUPERT J. HAMMOND-CHAMBERS PRESIDENT Taiwan Semiconductor Manufacturing Company (TSMC) is the world’s largest contract chip manufacturer. A key link in the global technology supply chain, it is the most important company most people have never heard of. TSMC, based in Taiwan, is now doubling down on its relationship with the United States in a big way. On Friday, May 15, 2020 TSMC announced the most important technology news of the year; the company committed to building a cutting-edge 5nm fabrication plant (fab) to produce semiconductor chips in Arizona. Its U.S. customers for the chips produced here will not only include U.S. tech companies, but will also include the Pentagon, defense contractors, and the national security community. The visionary founder of TSMC, Morris Chang, imagined a world where fabless semiconductor companies would absorb the financial burden of designing chips, but would outsource their actual production to his TSMC. His vision created a monster that dominates the sector he created - the foundry manufacturing sector – making almost 50% of all chips produced by foundries globally. TSMC’s state-of-the-art process technology and CAPEX investment of approximately US$15 billion/year ensures that it has few, if any, peers. Successive Taiwan governments have continued to nurture TSMC through prioritized access to land, power, and water, thereby allowing it to serve as the beating heart of Taiwan’s technology miracle.

  • Semiconductors: a Changing of the Guard
    Semiconductors: A Changing of the Guard Richard Spalton MA, CFA Investment Manager Semiconductors: A Changing of the Guard “While an early chip from the 1970s could fit thousands of micrometre-sized transistors, today’s most advanced chips are a complex web of billions of transistors, the smallest of which are just 10nm. To get some idea of how small that is: your fingernails grew 10nm in the time it took to read the previous sentence.”1 Background One of the key enablers of technological progress has been the constantly shrinking size of the transistors on semiconductor chips. Smaller transistors mean that the same number of computations can be completed faster, more efficiently and at lower cost. This concept was famously outlined by Gordon Moore, co-founder of Intel, who in 1965 wrote what became known as Moore’s Law. The manufacturing process for a particular size of transistor is called a process node. Shifting to a new node is highly complex and involves significant capital expenditure. In July 2020 Intel announced that their transition to the 7 nanometre node was running a year behind schedule. This delay will have a significant impact on Intel and its competitors. This announcement marks a changing of the guard in the semiconductor market, with leadership shifting away from Intel towards Taiwan Semiconductor Manufacturing Company (TSMC) and Samsung Electronics. Scale Matters Assessing the future prospects of a company requires an assessment of its industry. Manufacturing semiconductors is highly capital intensive – the industry spends USD 100bn per annum on capital expenditure. Companies also need to spend substantial amounts on R&D because each process node is more complex than the last.

  • Needham's Semiconductor Expertise What Does The
    The Growth Factor - Commentary by John Barr, [email protected] June 23, 2021 - Vol. 32 The Opportunity We See in Semiconductor Manufacturing (6 minute read) 2020 brought an unprecedented economic shutdown. The pandemic accelerated trends that we have been focused on for a long me; we call this the Great Digital and Life Sciences Acceleration. I would like to zero in on the opportunities in semiconductor manufacturing. I’ve long felt the semiconductor industry has moved beyond a cyclical, PC-driven industry to one of strategic importance. The confluence of manufacturing semiconductors for automotive, data center, machine learning, and remote work electronic systems; remaking the supply chain, and securing supplies for geopolitical needs have created a positive scenario for semiconductor manufacturing technology companies. Needham's Semiconductor Expertise Needham Funds have been owners of semiconductor manufacturing companies since our start in 1996. Needham Funds are an affiliate of Needham & Company, which has completed over 580 underwritings and M&A transactions for semiconductor companies since 1985. Addionally, prior to my Wall Street career, I spent 12 years in sales and markeng for Electronic Design Automaon companies, selling to semiconductor and electronic systems companies. I also spent 8 years as a sell-side senior research analyst following semiconductor design and technical soware companies. I served on the board of directors of venture capital-backed Coventor, Inc., which provided simulaon and modeling soluons for semiconductor process technology and was sold to Lam Research, Inc. in 2017. What Does the Opportunity in Semiconductor Manufacturing Mean for Needham Funds? Growth in advanced semiconductor manufacturing has been a dominant investment theme for Needham Funds for over 10 years.
