WebThese ingots are then sliced into wafers about 0.75 mm thick and polished to obtain a very regular and flat surface. Once the wafers are prepared, many process steps are necessary to produce the desired semiconductor integrated circuit. In general, the steps can be grouped into two areas: Front end processing Back end processing Processing WebMay 11, 2024 · The diamond abrasive process which is applied onto the silicon wafer edge, the so called “edge trimming,” is an important step in three-dimensional microelectronics processing technology, due to the significant thickness reduction of the wafer after thinning. Nevertheless, the wafer edge defects caused by edge trimming have often been … twitch live stream of buffalo shooting
