Abstract
Abstract A thermoelectric semiconductor multicouple array comprises a substrate of semi-insulating material 10, alternate n-type and p-type strips or legs ion implanted into said substrate and connected together electrically in series, and terminal means 11 connected to said series-connected strips or legs. The array may be incorporated in an integrated circuit chip. A method of making such thermoelectric semiconductor multicouple arrays is also disclosed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
82 words
A method of making a thermoelectric semiconductor multicouple array which comprises the steps of forming a surface of a semi-insulating material, ion implanting a first plurality of of strips of one conductivity type through a mask onto said surface, ion implanting a second plurality of strips of the opposite conductivity type through a mask onto said surface so that said second strips are disposed alternately between said first strips and the assembly of n-type and p-type strips are electrically connected in series.
Claim 2
Independent Claim
82 words

Claim 3
Dependent Claim
22 words
A method as claimed in claim 1, including the further step of applying contact members at the ends of said interconnected strips.
Claim 4
Dependent Claim
42 words
A method as claimed in claim 1, in which the surface of semi-insulating material is in the form of a sheet or wafer and a plurality of such sheets or wafers each bearing a said array are stacked side-by-side and interconnected together.
Claim 5
Dependent Claim
21 words
A method as claimed in claim 1, in which the surface of semi-insulating material is part of an integrated circuit chip.
