Title: Manufacture of semiconductor device
Inventor: HONDA YOSHIHIRO
IPC: H01L21/318
Filed: 1990-08-14
Abstract: PURPOSE:To make it possible to form a protective film having good step coverage even when there exists a hard step state on a substrate, by performing a formation of a PE-SiN film and an RIE processing in succession through combining the formation of the PE-SiN film with the RIE art when forming the film. CONSTITUTION:After forming an Al wiring 11, a Pad PSG film 12 is formed by an AP-CVD. Then, by a PE-CVD, a PE-SiN film 13 of about 500-1000Angstrom  in film thickness is formed. Thereafter, changing the conditions of a plasma output and the degree of gaseous vacuum (CF4, etc.) in an identical furnace, an RIE is performed, and a PE-SiN film 14 is generated as a protective film. Repeating this process, by only changing the program of a PE-CVD apparatus, the repeated processes of forming film-RIE-forming film-RIE..., are made possible, and the PE-SiN proceeds to be generated, while being subjected to an anisotropic etching. Therefore, overhangs are eliminated, and by only changing a generating rate and etching rate, even when a wide variety of steps existing on a substrate, the protective film having good step coverage which is made of a PE-SiN film 15 is obtained.

IPC: H01S5/02
Filed: 1987-08-27
Abstract: PURPOSE:To prevent falling of a bar-shaped semiconductor laser from a jig for forming the end-surface protecting film of the semiconductor laser and to prevent the formation of the protecting film on the entire surface of the electrode of the semiconductor laser, by attaching a spacer between the bar- shaped semiconductor laser and a cover. CONSTITUTION:A bar-shaped semiconductor laser 103 is coupled into the groove part of a base 101 so that an active layer 104 is positioned at the upper side. A spacer 107 comprising single crystal silicon is coupled from the upper side and fixed with a cover 102. A part of an electrode 105 is exposed from the spacer 107. The upper part of the groove is widely formed so that an evaporating agent for protection is sufficiently applied to an end surface 106 of a resonator. In this way, the upper side of the bar-shaped semiconductor laser 103 is pushed with the spacer 107, which is slightly narrower than the width of the bar-shaped semiconductor laser, and the spacer 107 is fixed with the groove at both end parts of the base 101. Therefore, the bar-shaped semiconductor laser 103 does not fall out of the jig, and the protecting film is not formed on the entire surface of the electrode 105.

Filed: 1982-12-08
Abstract: PURPOSE:To interrupt fuel supply appropriately, by judging the conditions for interrupting fuel supply on the three parameters of the vehicle speed, transmission ratio and deceleration switch. CONSTITUTION:A vehicle-speed sensor 13 produces a signal having a pulse number proportional to the vehicle speed by effecting ON-OFF switching of a reed relay at the timing sinchronous with the rotation of a magnet fixed to a speedometer cable. A deceleration sensor 14 is constituted by an idle switch and an aimed transmission ratio calculating circuit 35 calculates an aimed gear position obtaining a minimum specific fuel consumption from the output signals of a throttle-opening sensor 12 and the vehicle-speed sensor 13. A comparator 35-1 detects the difference between an aimed transmission ratio and the actual transmission ratio from the output signal of the circuit 35 and the signal representing the actual transmission ratio, given from a transmission ratio control lever 21. A circuit 37 for judging the fuel supply interrupting conditions is furnished with output signals of the deceleration sensor 14 and the vehicle-speed sensor 13 and the output signal of the transmission ratio control lever 21 representing the transmission ratio at the time. The circuit 37 turns OFF a ''fuel cut'' switch 33 by producing a control signal in case that the fuel supply interrupting conditions are satisfied. Further, the circuit 37 is also furnished with the output signal of a water-temperature sensor 15, and in case that the water temperature detected by the sensor 15 is equal to or lower than 60 deg.C, fuel supply is not interrupted since the engine is under warm-up in this state.

IPC: G11B27/10
Filed: 1987-08-28
Abstract: PURPOSE:To shorten a seek time by providing a positioner with an exterior scale and possessing a learning function for minimizing a moving time of the positioner. CONSTITUTION:When an target track seek command comes from a host device, a CPU 1 reads a presently positioned track address, and calculates a difference T from the target track, and then calculates a moving amt. of the positioner 15 from T track. Then, a correction value of the positioner moving amt. at the time of seeking the T track difference is read out of a ROM 7 by the CPU 1, so that the positioner seek of fine movement is carried out. Then, the correction value of the ROM 7 is turned into a mean value, and then put into a RAM 8, thereby correcting further the characteristics of individual devices and the characteristics of a medium. By this method, the seek operation can be speeded up.
