Statistics 3.58: Yashchin (1995) discusses a process for the chemical etching of sillicon wafer used in integrated circuits. This process etches the layer of silicon dioxide until the layer of mental beneath is reached. This company moniters the thickness of the silicon oxide layer because thicker layers require longer etching times. Historically, the layer has a true mean thickness of 1 micron and a standard deviation of 0.06 micron.
