The purpose of this document is to serve as the final report for work performed for Delco Electronics for the period January 1, 1986 through May 15, 1989. A computer program, SCAP2D (Solar Cell Analysis Program in 2- Dimensions) has been successfully converted to enable the simulation of bipolar transistors, including Delco’s thin-epi transistor. This code will be referred to as DAP 2D (Device Analysis Program in 2-Dimensions). Complete source code of DAP 2D is being released to Delco Electronics. This report is organized as follows. Chapter 2 provides a review of the numerical device modeling and discusses code enhancements completed during the last contract year. Chapter 3 shows results obtained by simulating generic bipolar transistors, including polysilicon contacted emitter bipolar transistors. Chapter 4 shows results obtained from simulations of Delco’s thin-epi bipolar transistor. These chapters are intended to show the usefulness of DAP2D in analyzing and designing bipolar transistors. The appendices contain a user’s guide, as well as a complete simulation example.
