(EN) IMPROVED DEPOSITION OF TUNGSTEN NITRIDE USING PLASMA PRETREATMENT IN A CHEMICAL VAPOR DEPOSITION CHAMBER
(KO) 화학 기상 증착 챔버에서 플라즈마 예비처리를 통한질화텅스텐의 개선된 증착
Abrégé
(EN)

A layer of tungsten nitride is deposited on the upper surface of a wafer with improved adhesion. The deposition is performed by first pretreating the wafer with a hydrogen plasma prior to performing tungsten nitride deposition.
