Title: Forming method for bonding pad of semiconductor chip
Inventor: AKISAWA TETSUO
IPC: H01L21/60
Filed: 1980-10-31
Abstract: PURPOSE:To enable the microminiaturization of a semiconductor chip by removing a passivation film of a bonding pad with resist mask and forming metallic layer having good bonding property on the exposed metallic layer by a lift-off method, thereby reducing the thickness of an internal wire. CONSTITUTION:A wiring layer 3 made of Al-Si layer is formed on an Si substrate 1 via an SiO2 film 2, and is covered with a passivation film made, for example, of Si3N4 film 4. A resist mask 5 is formed on the bonding pad forming protion of the element, a hole is opened at the film 4, a pure aluminum film is, for example, deposited, and a pad electrode 7 is formed. It is so set that the thickness of total sum of the film 4 and the layer 5 becomes larger than that of the aluminum deposited layer, and the aluminum layer 6 adhered onto the resist is lifted off simultaneously upon removal of the resist. In this manner, the bonding can be improved even if the layer 3 is reduced in thickness, thereby forming the wiring pattern in microminiaturized and high density manner.

Title: Optical disk device
Inventor: ICHIYANAGI TOSHIMITSU
IPC: G11B19/20
Filed: 1986-06-30
Abstract: PURPOSE:To reduce the size and weight of an optical disk device by dividing the frequency of a pulse motor driving reference clock and calculating the rotational angle of a disk in accordance with the frequency-divided result. CONSTITUTION:A motor reference clock CLK outputted from a CPU 13 to drive a pulse motor 11 is inputted to a motor 11 and a frequency divider 14. When a clock CLK is inputted only by 1/256 revolution of an optical disk 12 e.g., the frequency divider 14 outputs one pulse pulse TPLS. When 256 pulses SCTPLS are inputted, i.e. the disk 12 is rotated by one revolution, a sector counter 15 outputs one index signal INDX. Consequently, the reading or writing position of information from/in an information recording layer by a laser radiation part is controlled based on the count value of the counter 15. Since the position detection can be executed with an extremely simple constitution, the production cost of the device can be reduced and the size and weight of the device can be also reduced.

IPC: H04S5/02
Filed: 1983-08-22
Abstract: PURPOSE:To attain a good realism by connecting left and right control signal input terminals to variable gain controllers and obtaining stereo sounds with signal ''1'' and ''0''. CONSTITUTION:When signal ''1'' is impressed to an input terminal 13 from a signal source such as a computer or the like, an attenuator 29 is subjected to gain attenuation control by this signal. Therefore, sounds of a speaker in the rear right are lower than sounds of a speaker 7 in the rear left, and game sounds are heard as if they were flowed from the front to the rear left while describing a curve. When signal ''1'' is impressed to a terminal 14, an attenuator 30 is subjected to gain attenuation control by this signal, and sounds of the speaker 7 are made lower than sounds of the speaker 6. Therefore, game sounds are heard as if they were flowed from the front to the rear right while describing a curve; and thus, a realism is attained.
