The present invention relates to a method for fabricating a complementary metal-oxide semiconductor image sensor. The absorption refrigerating machine includes an evaporator, an absorber, a condenser, a high-temperature regenerator, a low-temperature regenerator, a low-temperature solution heat exchanger, and solution paths and refrigerant paths by which these units are connected. The upper edges of the supporting walls extend abruptly downwardly from the peak portions to a lower rear wall to provide relief at the rear of the stabilizer.
