Abstract

Official abstract text for this publication.

An amorphous silicon film formation method includes transferring a base in a process chamber, heating the base in the process chamber, setting a process pressure inside the process chamber, forming a seed layer on a surface of the base by flowing aminosilane-based gas in the process chamber under a process condition in which the aminosilane-based gas is not thermally decomposed and adsorbing the aminosilane-based gas onto the surface of the base, the process condition having a first temperature, and forming an amorphous silicon film on the seed layer by heating the base at a second temperature higher than the first temperature, flowing silane-based gas containing no amino group in the process chamber, and thermally decomposing the silane-based gas containing no amino group, wherein the forming of the seed layer and the forming of the amorphous silicon film are successively performed in the process chamber.

First claim

Opening claim text (preview).

What is claimed is: 1. An amorphous silicon film formation method comprising: transferring a base in a process chamber; heating the base in the process chamber; setting a process pressure inside the process chamber by evacuating an interior of the process chamber; forming a seed layer on a surface of the base by flowing aminosilane-based gas in the process chamber under a process condition in which the aminosilane-based gas is not thermally decomposed and adsorbing the amino…
