Patent ID: 7730605

Claim:
A method of fabricating a heat dissipating apparatus having only one accommodation cavity, comprising: providing two highly heat conductive substrates, each of the two substrates having an outer surface and continuously exposed inner surface formed with structured patterns; forming a highly heat conductive layer on the structured patterns of the highly heat conductive substrates; forming a micro-structure layer from said highly heat conductive layer; and assembling said two highly heat conductive substrates to form the only one accommodating cavity having the micro-structure layer formed with different profile heights from the structured patterns, thereby forming the heat dissipating apparatus having the micro-structure layer of a precise geometric dimension that corresponds to the structured patterns, wherein the single accommodating cavity is filled with a working fluid, and the working fluid is adhered to a portion of the micro-structure layer with a lowest profile height in the highly heat conductive substrates of all the continuously exposed inner surface of each of the two substrates; and the two outer surfaces are parallel and of equal dimension to each other.
