Toshiba TLCS-12, a microprocessor developed for the Ford EEC (Electronic Engine Control) system in 1973. [11] Intel 8080 CPU launched in 1974 was manufactured using this process. [96] The Television Interface Adaptor, the custom graphics and audio chip developed for the Atari 2600 in 1977. [97]
Chip-on-flex (COF), a variation of COB, where a chip is mounted directly to a flex circuit. Tape-automated bonding process is also a chip-on-flex process as well. Chip-on-glass (COG), a variation of COB, where a chip, typically a liquid crystal display (LCD) controller, is mounted directly on glass.
A microscope image of an integrated circuit die used to control LCDs.The pinouts are the dark circles surrounding the integrated circuit.. An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections.

TSOPs are rectangular in shape and come in two varieties: Type I and Type II. Type I ICs have the pins on the shorter side and Type II have the pins on the longer side. The table below shows basic measurements for common TSOP packages. [3]
Since only a few packages are chip size, the meaning of the acronym was adapted to chip-scale packaging. According to IPC 's standard J-STD-012, Implementation of Flip Chip and Chip Scale Technology , in order to qualify as chip scale, the package must have an area no greater than 1.2 times that of the die and it must be a single-die, direct ...
Shrink small-outline package (SSOP) chips have "gull wing" leads protruding from the two long sides, and a lead spacing of 0.65 mm (0.0256 inches) or 0.635 mm (0.025 inches ). [4] 0.5 mm lead spacing is less common, but not rare. The body size of a SOP was compressed and the lead pitch tightened to obtain a smaller version SOP.
Wafer-scale integration (WSI) is a system of building very-large integrated circuit (commonly called a "chip") networks from an entire silicon wafer to produce a single "super-chip". Combining large size and reduced packaging, WSI was expected to lead to dramatically reduced costs for some systems, notably massively parallel supercomputers but ...
The yield is often but not necessarily related to device (die or chip) size. As an example, in December 2019, TSMC announced an average yield of ~80%, with a peak yield per wafer of >90% for their 5nm test chips with a die size of 17.92 mm 2. The yield went down to 32% with an increase in die size to 100 mm 2. [189]
