Title:
METHOD OF FORMING GERMANIUM THIN FILM
Document Type and Number:
Japanese Patent JP2013181231
Kind Code:
A
Abstract:
To provide a method of forming a germanium thin film, by which film thickness can be made smaller while any structure concerned about characteristics of a semiconductor device is prevented from being caused and appropriate flatness is maintained.
A method of forming a germanium thin film includes a step of forming a germanium seed layer by absorbing a germanium on a surface of an underlying film using an amino-german-based gas (step 1), and a step of forming a germanium thin film on the germanium seed layer using a german-based gas (step 2).
