Usage

problem2.39

Format

In 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 of this process. two different etching solutions are being evaluated. Eight randomly selected wafers have been etched in each solution, and the observed etch rates (in mils/min) are reported.
