Abstract: PURPOSE:To reduce the capacity between interconnections and to realize the high speed of a circuit operation by forming the following for a passivation film: a low- temperature oxide film with which the surface of a metal interconnection is covered; an insulating film which has been formed at least on the surface of the low-temperature oxide film, with which a recess is filled and which has been coated and formed; and a low-temperature silicon nitride film at the uppermost layer. CONSTITUTION:A field silicon dioxide film 12 is grown on a silicon substrate 11. An aluminum interconnection 13 is formed on it. A first-layer plasma silicon dioxide film 14 with which the whole surface is covered is formed. It is coated with liquid silica; an annealing treatment is executed; after that, the coating film is etched back; a silica film 17 is formed. Then, a second-layer plasma silicon dioxide film 16 is grown; after that, a plasma silicon nitride film 15 is grown as a passivation film at the uppermost layer. In this manner, before the low-temperature silicon nitride film 15 for passivation use is formed, a recess in the aluminum interconnection 13 is filled with the insulating film 17 which has been coated and formed, and it is flattened. Thereby, the capacity between interconnections is reduced and the high speed of a circuit operation can be realized.

Title: Back plate
Inventor: KIDERA ATSUSHI
IPC: C04B35/00
Filed: 1990-11-19
Abstract: PURPOSE:To make a back plate high in streugth of connection to friction material, light weighted, not getting rusty, and hard to transmit friction heat at the time of applying a brake to the back plate by constituting the back plate of cermics compound material provided with uneven patterns over the whole surface of friction material connection face. CONSTITUTION:Material of a back plate 1 is suitably chosen while increase in an area is attempted by processing a connection face of the back plate 1 in an uneven plate for the sake of keeping connecting force to a disc pad. Since adhesive strength is proportional to an area, it is possible to easily increase adhesive strength. Processing of the surface can be easily performed by press method during a manufacturing process for a brake pad consisting of ceramics compound material. The ceramics compound material is a rustless material, and light weight and yet poor heat conductivity are desirable as the back plate 1 especially in comparison with iron. Moreover, heat conductivity of the ceramics compound material is smaller in comparison with iron, and accordingly it has an advantage not transfering friction heat of a brake to a brake mechanism.
