CMOS compatible microchannel heat sink for cooling electronic components and its fabrication

2015-9-30
The present invention is a CMOS compatible polymer microchannel heat sink for electronic cooling applications. The heat sink can be fabricated directly on the chip surface with an insulation layer by standard polymer surface micromachining techniques. The heat sink device comprises a thin insulation layer on the chip surface, a thin-film metal layer as bottom surface, metal side walls, and a polymer top wall over the microchannels and inlet-outlet reservoirs.

A novel complementary metal oxide semiconductor (CMOS) compatible microchannel heat sink is designed, fabricated, and tested for electronic cooling applications. The proposed microchannel heat sink requires no design change of the electronic circuitry underneath. Therefore, microchannels can be fabricated on top of the finished CMOS wafers by just adding a few more steps to the fabrication flow.

The production of low cost, large area display systems requires a light emitting material compatible with the standard silicon (Si) based complementary metal oxide semiconductor (CMOS) technology. The crystalline bulk Si is an indirect band semiconductor with very poor optical properties. On the other hand, hydrogenated amorphous Si (a-Si:H) based wide gap alloys exhibit strong visible photoluminescence (PL) at room temperature, owing to the release of the momentum conservation law. Still, the electrolumine...

Laser processing applied to thin film silicon is a practical tool for fabrication of thin film transistors and solar cells. Application of laser processing technologies to silicon based photovoltaics has been on the rise. Two examples out of plenty are: crystallization of amorphous Si (a-Si) thin films to produce polycrystalline Si (poly-Si) thin films; and quality improvement of poly-Si structures on the silicon wafer surface by laser annealing. Parameters for optimal crystalline silicon fabrication depend...

A novel complementary metal oxide semiconductor (CMOS) compatible microchannel heat sink is designed and fabricated for monolithic liquid cooling of electronic circuits. The microchannels are fabricated with full metal walls between adjacent channels with a polymer top layer for easy sealing and optical visibility of the channels. The use of polymer also provides flexibility in adjusting the width of the channels allowing better management of the pressure drop. The proposed microchannel heat sink requires n...
