INTEGRATED CIRCUITS Introduction
INTEGRATED CIRCUITS Introduction Integrated circuits (ICs) are a keystone of modern electronics. They are the heart and brains of most circuits. They are the ubiquitous little black “chips” you find on just about every circuit board. Unless you’re some kind of crazy, analog electronics wizard, you’re likely to have at least one IC in every electronics project you build, so it’s important to understand them, inside and out. Integrated circuits are the little black “chips”, found all over embedded electronics. An IC is a collection of electronic components – resistors, transistors, capacitors, etc. – all stuffed into a tiny chip, and connected together to achieve a common goal. They come in all sorts of flavors: single-circuit logic gates, op amps, 555 timers, voltage regulators, motor controllers, microcontrollers, microprocessors, FPGAs…the list just goes on-and-on IC Packages The package is what encapsulates the integrated circuit die and splays it out into a device we can more easily connect to. Each outer connection on the die is connected via a tiny piece of gold wire to a pad or pin on the package. Pins are the silver, extruding terminals on an IC, which go on to connect to other parts of a circuit. These are of utmost importance to us, because they’re what will go on to connect to the rest of the components and wires in a circuit. There are many different types of packages, each of which has unique dimensions, mounting-types, and/or pin- counts. Polarity Marking and Pin Numbering All ICs are polarized, and every pin is unique in terms of both location and function. -

PDF Package Information
This version: Apr. 2001 Previous version: Jun. 1997 PACKAGE INFORMATION 1. PACKAGE CLASSIFICATIONS This document is Chapter 1 of the package information document consisting of 8 chapters in total. PACKAGE INFORMATION 1. PACKAGE CLASSIFICATIONS 1. PACKAGE CLASSIFICATIONS 1.1 Packaging Trends In recent years, marked advances have been made in the electronics field. One such advance has been the progression from vacuum tubes to transistors and finally, to ICs. ICs themselves have been more highly integrated into LSIs, VLSIs, and now, ULSIs. With increased functions and pin counts, IC packages have had to change significantly in the last few years in order to keep-up with the advancement in semiconductor development. Functions required for conventional IC packages are as follows: 1) To protect IC chips from the external environment 2) To facilitate the packaging and handling of IC chips 3) To dissipate heat generated by IC chips 4) To protect the electrical characteristics of the IC Standard dual-in-line packages (DIP), which fulfill these basic requirements, have enjoyed wide usage in the electronics industry for a number of years. With increasing integration and higher speed ICs, and with the miniaturization of electronic equipment, newer packages have been requested by the industry which incorporate the functions listed below: 1) Multi-pin I/O 2) Ultra-miniature packages 3) Packages suited to high density ICs 4) Improved heat resistance for use with reflow soldering techniques 5) High throughput speed 6) Improved heat dissipation 7) Lower cost per pin In response to these requests, OKI has developed a diversified family of packages to meet the myriad requirements of today’s burgeoning electronics industry. -

Electronic Materials and Components-Semiconductor Packages
Electronic materials and components-Semiconductor packages Semiconductor ‘back-end’ processes We will learn much more about semiconductor ‘back end’ processes in subsequent modules, but you need to understand at least something of the terminology and what is involved in turning a ‘chip’ into a finished package1. 1 It is always very dangerous to point people at sources of information on packaging, especially now that the wonderful Fullman site has disappeared. However, you might like to take a look at what a doctoral student can achieve at http://chenjian.virtualave.net/packaging. The starting point for semiconductors is the wafer, which contains a (very large) number of devices, separated by small gaps, and electrically isolated from each other as part of the processing. Starting with a blank wafer of extremely pure silicon, building up layers by deposition techniques, etching patterns, and implanting dopants into the silicon structure using high energy particles, the semiconductor ‘fab’ ships a wafer which is partially probe-tested, but needs terminations in order to communicate with the outside world. These ‘front end’ processes attract the headlines, but the back end of the pantomime horse is just as important! The ‘back end’ process consists of sawing the wafer into individual dice (the terms ‘chip’ and ‘die’ are equivalent), mounting the die on a lead-frame or other mount using conductive adhesive, and finally making fine wire connections to the top surface – this ‘wire bonding’ process uses gold and aluminium wires typically 25-33 µm in diameter. Because wires and semiconductor are relatively fragile and easy to contaminate, the die will then be protected in some way. -
