Abstract
A process for making a integrated circuits of different typed is described wherein sequence of mask steps is applied to a substrate or epitaxial layer of p-type material. The sequence is chosen from a predefined common set of mask steps according to the particular type of integrated circuit to be fabricated. In this way, various types of integrated circuit can be fabricated in a most efficient manner.
