Feature size is determined by the width of the smallest lines that can be patterned in a semiconductor fabrication process, this measurement is known as the linewidth. Patterning often refers to photolithography which allows a … See more

When feature widths were far greater than about 10 micrometres, semiconductor purity was not as big of an issue as it is today in device manufacturing. In the 1960s, workers could work on semiconductor devices in street clothing. As devices become … See more

In semiconductor device fabrication, the various processing steps fall into four general categories: deposition, removal, patterning, and … See more

This is a list of processing techniques that are employed numerous times throughout the construction of a modern electronic device; this list does not necessarily imply a specific order, nor that all techniques are taken during manufacture as, in practice the order and which … See more

A typical wafer is made out of extremely pure silicon that is grown into mono-crystalline cylindrical ingots (boules) up to 300 mm (slightly less than 12 inches) in diameter using the See more

The highly serialized nature of wafer processing has increased the demand for metrology in between the various processing steps. … See more
