Abstract

Abstract A method for depositing a thin metal film in a vacuum on a surface of a substrate which comprises the steps of: (a) irradiating the surface of the substrate with a beam of ions of an inert gas or a metal, having a kinetic energy ranging from 100 eV to 1,000 eV; and (b) depositing vaporized metal on the surface of the substrate, in which the ratio of the amount of ions irradiating the surface to the amount of vapor deposited on the surface ranges from about 0.5% to 30% and wherein the temperature of the substrate ranges from about room temperature to 500 DEG C. n

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 107 words
A method for forming a thin metal film in a vacuum on a surface of a substrate, said method comprising the steps of: irradiating said surface of said substrate with a beam of ions of an inert gas or a metal, said ions having a kinetic energy ranging from 100 eV to 1,000 eV; and depositing vaporized said metal on said surface of said substrate wherein the ratio of the amount of said ions irradiating said surface to the amount of vapor deposited on said surface ranges from about 0.005 to 0.3 and wherein the temperature of said substrate ranges from about a room temperature to 500°C.
Claim 2
Independent Claim 107 words
A method for forming a thin metal film in a vacuum on a surface of a substrate, said method comprising the steps of: irradiating said surface of said substrate with a beam of ions of an inert gas or a metal, said ions having a kinetic energy ranging from 100 eV to 1,000 eV; and depositing vaporized said metal on said surface of said substrate wherein the ratio of the amount of said ions irradiating said surface to the amount of vapor deposited on said surface ranges from about 0.005 to 0.3 and wherein the temperature of said substrate ranges from about a room temperature to 500°C.
