Low-thermal-budget MOS gate stack formation using a cluster tool rapid-thermal-processing module

摘要

Abstract: Low thermal budget deposition of thin MOS gate stacks has been performed using a cluster tool rapid thermal processing module. This paper introduces the operational characteristics of the module, and the deposition conditions for gate oxide, nitride, and poly, in addition to spacer oxides. The different processing sequences for gate stacks are described, and finally the electrical characterization results of both rapid thermal chemical vapor deposition and conventional thermal MOS devices are compared.!11
