Class Information
Number: 438/344
Name: Semiconductor device manufacturing: process > Forming bipolar transistor by formation or alteration of semiconductive active regions > Washed emitter
Description: Process wherein the surface of the semiconductive substrate is etched to remove oxide layers formed on the emitter region during emitter diffusion thus allowing an aperature used for diffusing the emitter impurity to be directly utilized as the aperature for electrical contact formation.
