Problem 7E

An article in the IEEE Transactions on Electron Devices (November 1986, p. 1754) described a study on the effects of two variables—polysilicon doping and anneal conditions (time and temperature)—on the base current of a bipolar transistor. The data from this experiment follow.

(a) Is there any evidence to support the claim that either polysilicon doping level or anneal conditions affect base current? Do these variables interact? Use α = 0.05.

(b) Graphically analyze the interaction.

(c) Analyze the residuals from this experiment.

(d) Use Fisher’s LSD method to isolate the effects of anneal conditions on base current, with α = 0.05.
