A factory with excess capacity during slow periods could also run MOSIS designs to avoid having expensive capital equipment stand idle. Under-use of an expensive manufacturing plant could lead to the financial ruin of the owner, so selling surplus wafer capacity was a way to maximize the fab's use. Hence, economic factors created a climate ...
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.
This is a list of semiconductor fabrication plants, factories where integrated circuits (ICs), also known as microchips, are manufactured.They are either operated by Integrated Device Manufacturers (IDMs) that design and manufacture ICs in-house and may also manufacture designs from design-only (fabless firms), or by pure play foundries that manufacture designs from fabless companies and do ...
Note: Gate, source and drain contacts are not normally in the same plane in real devices, and the diagram is not to scale. Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process .
A typical fab will have several hundred equipment items. Semiconductor fabrication requires many expensive devices. Estimates put the cost of building a new fab at over one billion U.S. dollars with values as high as $3–4 billion not being uncommon. For example, TSMC invested $9.3 billion in its Fab15 in Taiwan.

TSMC agreed to expand its planned investment by $25 billion to $65 billion and to add a third Arizona fab by 2030, Commerce said in announcing the preliminary award. ... At full capacity, TSMC's ...
TAIPEI (Reuters) -Taiwanese chipmaker TSMC said on Tuesday it will build a second Japanese plant to begin operation by the end of 2027, bringing total investment in its Japan venture to more than ...
In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.
