The new Pope is of Italian descent, regardless of where he was born or what languages he speaks. Technically, Hispanic means related to Spain or Spanish culture, so perhaps he could be said to have Hispanic culture but not Hispanic origins.
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.
It also thins the wafer and helps to relieve stress accumulated in the wafer from the slicing process. Once the silicon wafers are lapped, they go through an etching and cleaning process using sodium hydroxide or acetic and nitric acids to alleviate microscopic cracks and surface damage caused by lapping.efore a semiconductor can be built, silicon must be transformed into a wafer. This begins with the growth of a silicon ingot. A single silicon crystal is a solid composed of atoms arranged in a three dimensional periodic pattern that extends throughout the material.
