  • Film uniformity is required in process development for a sheet-feeding epitaxial growth apparatus serving as an example of a vapor phase deposition apparatus. It is apparent that as a point which affects the film uniformity, the uniformity of a silicon wafer edge is given. This is a specific phenomenon, which is so-called an edge effect appearing at a wafer edge having several mm and which is different from a phenomenon at a wafer central portion. The phenomenon is very closely related to a temperature distribution, and a temperature distribution near the edge must be preferable. As will be described later, how to increase the temperature of a part of the holder with which the edge is in contact is a key to increase an edge temperature which tends to decrease. The method of heating the holder is devised. The method will be described below with reference to the drawings.
