Title: Ion implantation
Inventor: FUKUSHIMA HIDEKI
IPC: H01L21/265
Filed: 1986-10-27
Abstract: PURPOSE:To prevent breakdown of a dummy wafer and a regular wafer itself by using a material having a specific gravity similar to that of Si and being less easily splashed by ion implantation than the material of base at the wafer attaching position as the dummy wafer. CONSTITUTION:A predetermined number of regular wafers 3 are held at equal interval on the circumferencial edge of a disk type holder 2 and dummy wafers 14 made of aluminum which has a specific gravity similar to that of silicon and do not generate dust during ion implantation are also held on the vacant region. Aluminum is very convenient because it is also used for the disk type holder 2. The ion beam 10 emitted from a body 1 irradiates the holder in the constant direction with the constant incident angle. Here, the holder 2 is rotated and moved vertical by for the ion implantation to the entire part of wafer 3. According to this structure, rotation and vertical movement do not change due to loading of dummy wafers and these dummy wafers do not break due to the heat. When dummy wafers are changed to alumina wafers through the electrolytic grinding, the dummy wafer becomes resistive to adhesion of dust and to corrosion, and prevents generation of dust.

Abstract: PROBLEM TO BE SOLVED: To enhance workability in penetration and performance after embedding by forming an inside spiral blade having an area substantially closing a pile body inside in a plan in the inner periphery of the front end of the pile body. SOLUTION: An outside spiral blade 3 is formed at the outer periphery of the front end of a pile body 2 opened at the front end and the inside spiral blade 4 having an area substantially closing the inside of the pile body 2 in a plan at the inner periphery of the front end is formed in the same direction with the outside spiral blade 3.
