摘要

本文研究了利用金属离子注入形成CoSi/ sub2 //Si肖特基势垒的新技术。首次研究了其电子特性,包括I-V特性和C-V特性。注入参数:剂量3/spl次/10次/sup 17/离子/cm/sup 2/ Co;能源、20 kv。植入晶圆后,采用快速热退火(RTA)在850/spl℃下退火1分钟。I-V结果表明,势垒高度为0.64eV,理想因子为1.11。C-V结果提取的势垒高度为0.72eV。这项新技术需要改进。

CoSi/sub 2//Si Schottky junction formed by high flux metal ion implantation
In this paper we present the research of forming CoSi/sub 2//Si Schottky barrier through a novel technology - the metal ion implantation. The electronic characteristics including I-V and C-V characteristics were investigated for the first time. In implantation parameters: dose 3/spl times/10/sup 17/ion/cm/sup 2/ Co; energy, 20kV. After implantation the wafers were annealed for 1 minute at 850/spl deg/C by rapid thermal annealing (RTA). I-V results show that barrier height is 0.64eV and ideality factor is 1.11. The barrier height extracted from C-V results is 0.72eV. Improvements for this new technique are needed.
