Abstract: PURPOSE: A method for forming a metal pattern of a semiconductor device by using a low photoresist selectivity is provided to precisely form metal patterns by restraining the metal bridges from creating between the metal patterns. CONSTITUTION: A metal layer is deposited on a semiconductor substrate(20). A photoresist is coated on the metal layer. Then, the photoresist is patterned so as to form a photoresist pattern(30a). The metal layer is etched by using a reaction gas consisting of Cl2, BCl3 and Ar thereby forming a metal pattern(25a). When the etching process is carried out, the photoresist pattern(30a) is used as an etching mask. The etching process includes a plasma etching process. The reaction gas includes Cl2 of 50-90sccm, BCl3 of 50-90sccm, and Ar of 40-80sccm.

Abstract: PURPOSE: A refrigerator is provided to save the energy and to perform the starting of a compressor even if the power voltage is changed. CONSTITUTION: The refrigerator is composed of:a piece for controlling the revolution number of an electromotor(4) by controlling the chopping movement of a switching device consisting of an inverter or a converter(2) on the basis of the deviation between the set temperature and the temperature of a freezing chamber of a refrigerator; and an operating mode maintaining the revolution number of the electromotor(4) less than a specific value of the movement area by raising the set temperature.
