From Wikipedia, the free encyclopedia. A wafer, also called a slice or substrate, is a thin slice of semiconductor material, such as a crystalline silicon, used in electronics for the fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells.he boule is then sliced with a wafer saw (wire saw) and polished to form wafers. The size of wafers for photovoltaics is 100â200 mm square and the thickness is 200â300 Î¼m. In the future, 160 Î¼m will be the standard. Electronics use wafer sizes from 100â450 mm diameter.

Page 1. The Glasgow Coma Scales. The Glasgow Coma Scale (GCS) is the most widely used. scoring system used in quantifying the level of consciousness. following traumatic brain injury. It is used because it is simple, has a relatively high degree of reliability and correlates well with. outcomes following severe brain injury.
