Semiconductor equipment and refrigerator

Abstract

A freezer ( 106 ) is provided with a connector ( 120 ) and connected to a semiconductor equipment ( 10 ). The connector ( 120 ) may include a connector for power supply ( 120 a ), a connector for data communication ( 120 b ) and a connector for analog signal ( 120 c ). Therefore, the semiconductor equipment ( 10 ) can transmit data and signal to the outside while being cooled in the freezer ( 106 ). With this constitution, a semiconductor equipment housed in a cooling system for high-speed operation and a refrigerator for cooling the semiconductor equipment are provided.
