Abstract:
A device for sealing and cooling multi-chip modules, the multi-chip modules including a circuit substrate having a plurality of semiconductor devices mounted thereon, and a frame fixed to a peripheral area of a surface of the circuit substrate, the semiconductor devices mounted thereon and formed from a material having a thermal expansion coefficient which is substantially equal to that of the circuit substrate, the device for sealing and cooling multi-chip modules comprising:a sealing top plate, a surface thereof being formed with a cooling flow path grooves, an opposite surface thereof being bonded to the semiconductor devices surface opposite to a surface of the semiconductor device connected to the circuit substrate, and a peripheral area thereof joining the frame to form a first seal; a cooling flow path cover covering the cooling flow grooves and fixed to the frame path; and a sealing material for preventing leakage of a cooling fluid from the cooling flow path grooves by filling a gap between the peripheral area of the sealing top plate and peripheral area of the cooling flow path cover to form a second seal.
