Filed: 1994-11-14
Abstract: PURPOSE: To obtain an epitaxial thin film of high quality wherein etching irregularity is not generated on the back of a wafer, by a method wherein, after a specified treatment for forming films such as very thin thermal oxide films and CVD films on both surfaces of the wafer, the wafer is inserted in a reaction equipment and subjected to epitaxial growth. CONSTITUTION: After a specified treatment for forming films such as very thin thermal oxide films and CVD films on both surfaces of a wafer 1, it is mounted in an accommodation hole 11 of a susceptor 20 of a reaction equipment. On account of the difference of gas flow velocities of hydrongen 12 and 13 on the surface and the back of the wafer 1, an oxide film on the wafer surface side is completely eliminated during an epitaxial process. After that, the silicon wafer surface is etched by introducing hydrogen chloride gas, and a film is epitaxially formed by using silicon based gas. On the other hand, the oxide film is left on the wafer back side, and a silicon substrate itself on the wafer back side is not etched. Thereby a silicon epitaxial thin film of high quality wherein etching irregularity is not present can be obtained on the back of the wafer.

Title: Resin molding device with resin tablet temperature control mechanism
Inventor: TAKAHASHI KAZUHIDE
IPC: B29C45/02
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To strictly control the temperatures of a resin tablet storage place by providing a cooling means for keeping the internal chamber in which a tablet supply means is stored below a specified temperature level. SOLUTION: When the internal temperatures of a chamber are above a temperature level of 30 deg.C on account of the repetition of a resin molding step, a control part 21 adjusts the internal temperatures of the chamber to a constant temperature level of 30 deg.C or less by increasing the cooling capability of a cooling unit 22, as the temperatures are detected by a temperature sensor 6a.
