Abstract: PURPOSE:To obtain ceramic having excellent flexural strength at high temperature and excellent dimensional accuracy, by reacting a molded article comprising carbon as an essential component with molten silicon and nitriding a remaining metal silicon. CONSTITUTION:A composition obtained by blending 5-50wt.% carbon component-containing material (e.g. graphite) with 50-95wt.% SiC powder, 0.1-20wt.% binder (e.g. PVA) and a filler (e.g. Al2O3) to give a composition, which is packed into a mold and molded to give a molded article. Then the molded article is immersed in molten silicon, reacted and sintered in vacuum or in an inert atmosphere at 1,450-1,800 deg.C to give a sintered material. Then the sintered material is heated under 1-10atm in a nitrogen atmosphere at 1,300-1,600 deg.C to nitride a remaining metal silicon in the sintered material.

Title: Structure of metal substrate
Inventor: KIMURA TOSHIHIRO
IPC: H01L25/07
Filed: 1990-11-28
Abstract: PURPOSE:To contrive to improve the reliability of the structure of a metal base by a method wherein first and second metal bases are made to bond to each other in the direction vertical to the direction in which an insulating layer and a wiring layer are formed. CONSTITUTION:First and second base metal films 9 are formed into a constitution, wherein they are bonded to each other in the direction vertical to a direction, in which an insulating layer 3 and a wiring layer 4 are laminated. Accordingly, as heat generated from an electronic component generating much heat is dissipated in the air via the metal films 9 of a high heat conductivity, the heat is not accumulated at the junction part between a metal board 1 and the electronic component generating much heat. As a result, a temperature rise is not caused and a breakdown of a semiconductor element 5, which is caused by overheating, is prevented. Moreover, as the electronic component 5 generating a little heat is mounted on the metal film 9, which has little thermal expansion due to a temperature difference in the outside environment, the thermal expansion of the metal base 9 is a little and the stress can be lessened. As a result, the separation of the component 5 generating heat a little from the metal films 9 due to the thermal expansion is prevented. Thereby, the reliability of a structure consisting of the substrate 1 and the electronic component 10 can be improved.
