Patent number: 5895271Abstract: A metal film forming method by which a metal film having a desired pattern can be formed with good reproducibility and satisfactory precision. In a metal film forming method for forming a metal film into the desired pattern on a surface of an object by the lift-off method, a resist layer is laminated on the surface of the object, the resist layer is exposed to light with the desired pattern and it is developed. Radio frequency sputtering is then performed against the resist layer so that the opening is deformed into a shape which is suited for the lift-off process. A metal film is then laminated on the surfaces of the resist layer and the metal film forming object. Then the resist layer is subjected to lift-off processing, whereby the metal film can be formed with good precision and satisfactory reproducibility. In this way, such a metal film forming method can be realized that a metal film having the desired pattern can be formed with good reproducibility and satisfactory precision.Type: GrantFiled: December 27, 1995Date of Patent: April 20, 1999Assignee: Sony CorporationInventors: Kiyoshi Hasegawa, Hiroshi Ozaki

Patent number: 5774701Abstract: A microprocessor incorporating a PLL circuit using a clock pulse having a relatively low frequency as an input clock signal of a reference frequency to form an oscillating pulse of a relatively high frequency by multiplying the input clock signal. In the microprocessor, the operation of the PLL circuit is stopped in the low-speed mode to supply the clock pulse of the relatively low frequency to the microprocessor as a system clock signal, and, in the high-speed mode, the PLL circuit is activated upon reception of an event requiring high-speed processing. Until the operation of the PLL circuit is stabilized and the request for high-speed processing comes, the above-mentioned clock pulse having the relatively low frequency is kept supplied continuously to the microprocessor as the system clock signal. This novel setup permits the high-speed switching of the microprocessor from the operating mode to the high-speed operating mode.Type: GrantFiled: July 10, 1995Date of Patent: June 30, 1998Assignee: Hitachi, Ltd.Inventors: Shigezumi Matsui, Mitsuyoshi Yamamoto, Shinichi Yoshioka, Susumu Narita, Ikuya Kawasaki, Susumu Kaneko, Kiyoshi Hasegawa
