Abstract

In this paper, we discuss influence of process condition on contact resistance in WSix deposition process. In the WSix deposition process, we confirmed that word line to bit line contact resistance(WBCR) due to temperature of word line WSix deposition among various process condition split experiment. RTP treatment, d-poly ion implantation dose and thickness was estimated a little bit influence on contact resistance. Also, life time of shower head in the process chamber for WSix deposition related to contact resistance. The results obtained in this study are applicable to process control and electrical characteristics for high reliability and high density DRAM's.
