Filed: 1990-06-13
Abstract: PURPOSE:To obtain a superthin film excellent in crystal properties by etching a buried oxide film to remove it until the topside of the island-shaped silicon formed in the buried oxide film is exposed. CONSTITUTION:Oxygen ions are implanted into a silicon wafer 11 to form an oxygen ion implanted region in the wafer 11. And the upper layer of the wafer 11 is shaved off selectively by etching to form a cap layer 13, which has a specified step at the surface of the wafer 11 and consists of silicon. Next, the wafer 11 is heat-treated in argon atmosphere, whereupon the oxygen ions in the region 12 are activated, and a buried oxide film 14 is formed. At the same time, silicon 15 is formed, at the position corresponding to the step of the cap layer 13 accurately, within the oxide film 14. Then, the cap layer 13 is removed completely by etching, and the oxide film 14 is etched until the topside of the silicon 15 is exposed. As a result, an SIMOX wafer of superthin film SOI structure becomes favorable.

The information of the color recognition is converted into the name of the real material registered in advance and the PC of the name of the material is displayed on a display part 9. On the other hand, the information of the color recognition is transmitted to a movable rail 12d on the belt conveyer 11 and the movable rail 12d corresponding to a PC sort box 13d is operated so as to cross the belt conveyer 11. Thus, the part 7 after being moved in the direction of the arrow on the conveyer 11 is led to the movable rail 12d and collected into the PC sort box 13d for each material. After the classification is surely/mechanically completed in this manner, the reuse of a resource (recycling) is attained in each material.
