Abstract

Morphology is one of important issues when developing a layer of CVD-W. we need to control the process more precisely that is filling gaps between BL(bit line)and DC(direct contact). Whereas we are facing to difficulties like not-filling contacts due to marginal problems in deposition and etching process. This paper is for investigating a method to resolve morphology problem with strengthening the condition of seasoning.
