(과제) 실리콘 산화물막과 실리콘 질화물막과의 적층수를 늘려도, 이들 막을 적층한 적층 구조가 형성되는 기판의 휘어짐의 증대를 억제하는 것이 가능한 실리콘 산화물막 및 실리콘 질화물막의 적층 방법을 제공하는 것이다. (해결 수단) 기판(W) 상에, 실리콘 산화물막(1-1)과 실리콘 질화물막(2-1)을 적층하는 실리콘 산화물막(1-1) 및 실리콘 질화물막(2-1)의 적층 방법으로서, 실리콘 질화물막(2)을 성막하는 가스 중에, 붕소를 첨가한다.
Abstract:
PURPOSE: A method and an apparatus for forming a thin film are provided to improve step coverage by forming a boron-doped amorphous silicon film in a seed layer. CONSTITUTION: A source gas for a seed is supplied into a process chamber. The source gas includes an aminosilane based gas and a multi-functional silane gas. A seed layer(88) is formed on the surface of an insulating layer. The silane gas and an impurity-containing gas are supplied into the process chamber. An amorphous impurity-containing silicon layer(90) is formed. [Reference numerals] (2) Insulating layer(underlayer); (88) Seed layer; (90) Amorphous impurity-containing silicon layer;

PURPOSE: A film forming apparatus and a method for operating the same are provided to perform a carbon film forming process on a plurality of object surfaces and to maintain a tolerance pre-coating film. CONSTITUTION: A carbon film(74) is formed on a plurality of object surfaces. An unnecessary carbon film in a process chamber is removed. A cleaning process is performed using cleaning gas. A supporting device holds and supports the object. A tolerance pre-coating film(70) having tolerance against the cleaning gas is formed.

Abstract:
PURPOSE: A film forming apparatus and a method for operating the same are provided to improve the adhesion of a carbon film and to prevent the generation of particles. CONSTITUTION: A carbon film(74) is formed on a plurality of object surfaces. A supporting device holds and supports the object. A film forming process is performed in a process chamber(8) of quartz. An adhesion film(70) is formed on the surface of the quartz. The adhesion film improves the adhesion of the carbon film.
