Etch manufacturing
WebIn semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metalization. The etch rate is an important characteristic in this process and known to follow a normal distribution. Two different etching solutions have been compared, using two random samples of 10 wafers for each solution. WebWet-etching processes are used to chemically remove layers from the wafers' surface during their manufacturing. An automated wet-etch station (AWS) includes a series of successive chemical and water/de-ionizing baths and a shared material handling system, having one or more devices/robots, in charge of moving wafer lots from one bath to the ...
