Abstract
A reduced CTE composite structure is made by providing a matrix material whose CTE is to be reduced, adding negative CTE bodies to the matrix material and mechanically coupling the matrix material to the negative CTE bodies as by deforming the composite structure. A preferred application is to make an improved composite material for use as a heat sink for semiconductor substrates with a minimum of thermal expansion mismatch.
