Claim 0:
1. A method of forming a heat dissipating semiconductor wafer, comprising the steps of:
forming a first group of semiconductor dies on the heat dissipating semiconductor wafer, the first group of semiconductor dies being thermoelectric semiconductor dies, by the step of doping p-n regions at least in areas of the heat dissipating semiconductor wafer defining the first group of semiconductor dies such that a temperature gradient or voltage potential between first and second surfaces of a semiconductor die of the first group of semiconductor dies results in migration of charge carriers between the first and second surfaces of the semiconductor die;
wherein the heat dissipating semiconductor wafer is configured to be bonded to a second semiconductor wafer having a second group of semiconductor dies such that the first group of semiconductor dies align with the second group of semiconductor dies upon joining of the first and second semiconductor wafers.
