Abstract

Abstract Translated from Japanese (57)【要約】 【構成】 半導体装置の製造方法であって、不均一な厚 さを有するシリコン酸化膜13をシリコン膜上12に形 成する工程と、WF 6 を含むガスによってシリコン酸化 膜13の少なくとも一部を還元し、かつ、WF 6 とシリ コン膜12の露出した表面とを不均一に反応させなが ら、タングステン膜14をシリコン膜12上に成長させ る工程と、タングステン膜14を除去する工程とを包含 する。 【効果】 再現性よく、シリコン膜12の表面積を増加 することができる。 (57) Abstract: CONSTITUTION] A method of manufacturing a semiconductor device, comprising the steps of forming a silicon oxide film 13 having a non-uniform thickness to the silicon film 12, a silicon oxide film 13 by the gas containing WF 6 Of at least a part of the tungsten film 14 is reduced, and WF 6 and the exposed surface of the silicon film 12 are caused to react nonuniformly, and a step of growing the tungsten film 14 on the silicon film 12 and a step of removing the tungsten film 14. Includes and. [Effect] The surface area of the silicon film 12 can be increased with good reproducibility.
