Abstract

Abstract A cleaved surface of a crystal is used as a substrate for evaporation, and a high mobility semiconductor is evaporated to a thickness of 0.5 to 1.5 μm to form a deposited thin semiconductor film, on which a first magnetizable member having a high magnetic permeability is applied with an adhesive. Subsequently the substrate is removed, and an electrode is formed on the exposed surface of the evaporated thin film, and a second magnetizable member is applied thereon with an adhesive. Where a special humidity resistance is required, a reinforcing layer of an electrically insulating and moisture-impervious inorganic material is formed directly on the evaporated thin semiconductor film before the first magnetizable member is applied.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 101 words
A Hall element comprising: an evaporated thin film of a semiconductor having a high mobility and having a thickness of 0.5 to 1.5μ, separated from an evaporation substrate after evaporation; input electrodes and output electrodes formed on one surface of the evaporated thin film; a first magnetizable member bonded to said one surface of the evaporated thin film by a layer of adhesive disposed between said first member and said one surface; and a second magnetizable member bonded to the other surface of the evaporated thin film by a layer of adhesive disposed between said second member and said other surface.
Claim 2
Dependent Claim 101 words
A Hall element comprising: an evaporated thin film of a semiconductor having a high mobility and having a thickness of 0.5 to 1.5μ, separated from an evaporation substrate after evaporation; input electrodes and output electrodes formed on one surface of the evaporated thin film; a first magnetizable member bonded to said one surface of the evaporated thin film by a layer of adhesive disposed between said first member and said one surface; and a second magnetizable member bonded to the other surface of the evaporated thin film by a layer of adhesive disposed between said second member and said other surface.
Claim 3
Dependent Claim 35 words
A Hall element according to claim 1, further including a reinforcing layer of an electrically insulating and moisture-impervious inorganic material which is formed in direct contact with said other surface of the evaporated thin film.
Claim 4
Dependent Claim 34 words
A Hall element according to claim 2, further including a protective layer of electrically insulating and moisture-impervious inorganic material which is formed in direct contact with said one surface of the evaporated thin film.
