Supported by Delco Electronics


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.
