Chip-on-board (COB), a bare silicon chip, that is usually an integrated circuit, is supplied without a package (which is usually a lead frame overmolded with epoxy) and is attached, often with epoxy, directly to a circuit board. The chip is then wire bonded and protected from mechanical damage and contamination by an epoxy "glob-top".
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 ...
Apple A12 and Huawei Kirin 980 mobile processors, both released in 2018, use 7 nm chips manufactured by TSMC. [ 127 ] AMD began using TSMC 7 nm starting with the Vega 20 GPU in November 2018, [ 128 ] with Zen 2-based CPUs and APUs from July 2019, [ 129 ] and for both PlayStation 5 [ 130 ] and Xbox Series X/S [ 131 ] consoles' APUs, released ...
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.

A modern example of multi-chip integrated circuit packages would be certain models of microprocessor, which may include separate dies for such things as cache memory within the same package. In a technique called flip chip , digital integrated circuit dies are inverted and soldered to a module carrier, for assembly into large systems. [ 8 ]
Integrated circuit packaging is the final stage of semiconductor device fabrication, in which the die is encapsulated in a supporting case that prevents physical damage and corrosion. The case, known as a " package ", supports the electrical contacts which connect the device to a circuit board.
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5
Testing is carried out to prevent faulty chips from being assembled into relatively expensive packages. 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.
