Title:
METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2003297848
Kind Code:
A
Abstract:

To suppress contamination and secondary contamination in a semiconductor device due to a group IV element Si, which becomes a contaminant in a manufacturing method of the semiconductor device including Si and the group IV element except Si.

A Si/SiGe film formed on the rear face of a semiconductor wafer is removed by wet etching right after the Si/SiGe film including contaminants is formed by epitaxial growth, or dummy run using a container is performed after the Si/SiGe film is heated in the container. Secondary contamination via a stage where the wafer is treated, a robot arm or a pair of vacuum tweezers and the contamination of the container also used in a manufacturing process of the semiconductor device which does not include the group IV element except Si can be suppressed.
