Hi Leily, The easier solution will be to design and make a manifold that will connect to the chip from the sides. But, this might require the chip to be larger on the channel direction than the chip you want to cool. because the manifold fits to the diced side of the chip and it will be hard to glue it to the side and seal well enough without clogging the channel ends. You will want the manifold to seal above and below the chip.

The channels are 300 micron deep and the smallest width of channels is 50 microns. Another thing is that my coolant is a segmented glow containing liquid metal (Galinstan) and mineral oil, and Galinstan is corrosive to metals. I read in different literature that anodic bonding is used to cover the chip with glass. If I use the same process, how can I connect my inlet and outlet tubes to the chip to pump the coolant? Should I make holes on glass? I'd appreciate any help.
