Title: Method for adhering crystal
Inventor: KAGAWA TOSHIAKI
IPC: H01L21/203
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To adhere two crystals having different lattice constants by growing a crystal at least in vacuum and by heating under the condition of pressurizing and firmly contacting with another crystal continuously in vacuum without exposure in air. SOLUTION: A Mo block having an InP substrate is introduced into a load lock chamber 4 and after vacuum exhaust it is transferred to a preheating chamber 3 by opening a gate bulb. Here the Mo block is attached to a heater by operating a transfer rod 6 and after eliminating moisture by heating it is introduced into a growing chamber 1 through a vacuum chamber 2. After growing an epitaxial layer having a predetermined structure on the InP substrate, it is inversely returned into the vacuum chamber 2. On the other hand after an oxide film is eliminated by chemical etching of an Si substrate, it is attached to another Mo block. Bonding hands on the most upper surface of Si are terminated by hydrogen by means of the chemical etching and oxygen on the surface is almost eliminated.  The Mo block with Si is introduced into the preheating chamber 3 and crystals on the InP substrate and the Si substrate are made to face each other in vacuum and are pressurized and heated.
