Abstract
The invention is a structure for improving the cooling characteristics of a silicon semiconductor device immersed in a fluid coolant. The cooling improvement is achieved by enhancing the nucleate boiling characteristics of the silicon device by initially forming lattice defects on the backside surface of the device by sandblasting and subsequently etching the damaged surface to remove the lattice defects and thereby produce an intricate surface morphology which provides nucleate boiling sites.
