Digital Control of the Czochralski Growth of Gallium Arsenide-Controller Software Reference Manual

Abstract

This volume provides a complete description of the structure and the operation of the specific controller software developed for ASU's digital Czochralski Growth Control System (CGCS) for compound semiconductors. The manual is primarily intended for use by advanced programmers and crystal growth specialists. In four main chapters, the Controller Software Reference Manual discusses the design considerations applied to digital LEC crystal growth control, give a short overview over the growth controller computer hardware and operating system environment, describes the functions of the CGCS from an operator's point of view, and delineates the internal operations of the controller software by discussing the controller software and algorithms. Various appendices provide tables of controller software tasks, routines, and variables, file format information, and lists of system messages and error codes. Keywords: Gallium arsenides.
