Title: Inorganic article for growth of crystal
Inventor: KINOSHITA HIROAKI
IPC: C30B35/00
Filed: 1989-12-28
Abstract: PURPOSE:To efficiently allow a high quality crystal to grow, the crystal being reduced in the structural defects thereof, by applying the coating of amorphous carbon to all surface of a porous inorganic article employed for the growth of the crystal. CONSTITUTION:The uniform coating 1 with amorphous carbon is applied to the surface of a conventional graphite carbon boat 20 to seal numerous fine grooves 30 and holes 31 existing on the boat 20 and also flatten the surface of the boat 20. When a liquid epitaxy is performed using the boat 20, an epitaxial layer 4 having an uniform film thickness grows on the substrate 10 because any crystallization seed does not exist on the surface of the boat 20. Particularly, since the penetrated hole 31 is clogged, a volatile element having a high vapor pressure is not scattered outside the boat 20 through the penetrated hole 31 on the epitaxial growth.

Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of the covering property of metal in an electrode, even if a contact size is reduced by providing the constitution, wherein a silicon oxide film, in which nitrogen atoms are diffused in the vicinity of a gate electrode and a silicon nitride film is not provided at the side surface of an opening part for electrode lead-out. SOLUTION: A first interlayer silicon oxide film 5 is provided on a transistor. The upper part of the film becomes a silicon-nitride oxide layer 5a formed by diffusing nitrogen atoms from the outside. Furthermore, a second interlayer silicon oxide film 7, which becomes an insulating-layer intermediate film between a wiring and a substrate, is provided on the layer 5a. A contact hole 8, which is the opening part for drawing the electrode from the source/drain diffused layer, is provided on a high-concentration N-type diffused layer 22 for the source/drain. When the contact hole 8 is opened, the silicon nitride film has already been removed. Therefore, even if titanium nitride titanium 9 is sputtered as an electrode in the inside, the decrease in covering property caused by the eave of the silicon nitride film does not occur.
