Patent number: 6114052Abstract: An ingot plate (10) of cleaveable thermoelectric material has a layered structure having substantially parallel cleavage planes. Substantially all of the cleavage planes are disposed at a less cleavage angle with respect to the upper and lower faces (11, 12) of the plate. The ingot plate can be successfully cut into bars (20) along cutting planes generally perpendicular to the cleavage planes without causing substantial interlayer fracture. Electrodes (25) are formed on the opposite sides of the bar which are defined by the cutting planes. The bar is in use to be cut into a number of discrete chips (30) with one of the electrodes fixed on a substrate. Since the cutting is made along planes again generally perpendicular to the cleavage planes of the bar, the bar can be successfully cut into the corresponding chips without causing any substantial fracture.Type: GrantFiled: August 12, 1998Date of Patent: September 5, 2000Assignees: Matshsuhita Electric Works, Ltd., Crystal Ltd.Inventors: Nobuteru Maekawa, Belov Iouri Maksimovich
