Abstract

Abstract In an apparatus for forming an aluminum thin film, or an aluminum alloy thin film useful to an interconnecting material of an electronic device, there are provided: a processing chamber capable of keeping a vacuum condition therein; a substrate holder mounted within said processing chamber, for holding a substrate and performing a temperature adjustment; a first temperature adjusting mechanism for performing the temperature adjustment of said substrate via said substrate holder; whereby a part of element consisting said predetermined gas is deposited on the surface of said substrate; a gas conducting mechanism for conducting a predetermined gas into said processing chamber; an exhausting mechanism for exhausting an interior of said processing chamber; a distributing plate provided within said processing chamber, for uniformly supplying said predetermined gas to a surface of said substrate; and a second temperature adjusting mechanism for adjusting the temperature of said distributing plate.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 87 words
In an electronic device having an interconnecting material formed from either an aluminum film or an aluminum alloy film, made by a method of forming said film as a single crystal film, comprising the steps of: heating a predetermined gas to produce a thermal variation at a first stage; supplying said heated gas to a surface of a substrate; heating said substrate to a thermal variation in a second stage; and forming said film by thermal CVD (chemical vapor deposition) method on said surface of said substrate.
Claim 2
Dependent Claim 87 words
In an electronic device having an interconnecting material formed from either an aluminum film or an aluminum alloy film, made by a method of forming said film as a single crystal film, comprising the steps of: heating a predetermined gas to produce a thermal variation at a first stage; supplying said heated gas to a surface of a substrate; heating said substrate to a thermal variation in a second stage; and forming said film by thermal CVD (chemical vapor deposition) method on said surface of said substrate.
Claim 3
Dependent Claim 34 words
An electronic device as claimed in claim 1, wherein said substrate is a silicon substrate, and wherein said forming step comprises: forming an aluminum epitaxial growth film on a surface of said silicon substrate.
Claim 4
Dependent Claim 35 words
An electronic device as claimed in claim 1, wherein said substrate is a silicon substrate, and wherein said forming step comprises: forming an aluminum-silicon substrate epitaxial growth film on a surface of said silicon substrate.
