Title: Manufacture of insulated gate field-effect semiconductor device
Inventor: TANAKA TADAHIKO
IPC: H01L29/78
Filed: 1981-09-18
Abstract: PURPOSE:To avoid the shortening of channel length by projecting the bent section of a common mask and making the width of a reverse conduction type gate region larger than other sections when the reverse conduction type gate region and one conduction type source region are formed to one conduction type semiconductor substrate through double diffusion by using the common mask. CONSTITUTION:When the reverse conduction type gate region 2 and one conduction type source region 3 positioned into the region 2 are shaped to one conduction type semiconductor substrate 1 through double diffusion by employing the common mask 10 consisting of SiO2, etc., the mask 10 is formed as follows. That is, the rectangular projections 11 obliquely projected to the corner sections of the mask 10 are shaped previously, and the regions 2, 3 are formed through diffusion. Accordingly, since the regions 2, 3 spread under the mask 10 only by the diffusion depth, the ends of the regions 2 enter to the inside only by d from the mask 10 when the diffusion depth of the regions 2 is d. When the width l of the projections 11 is set previously to the condition of l<2d, the gate regions 2 are also generated under the projections 11, and the channel length of the regions 2 is lengthened.

IPC: H02P9/14
Filed: 1978-11-30
Abstract: PURPOSE: To increase the control characteristic and improve the stability by using the combination of the rotor speed variation signal and the power variation signal.  
     CONSTITUTION: A signal obtained by adding a signal from an uncomplete differential circuit 21 to which a signal Δω proportional to the rotor speed variation of a generator to a signal from an uncomplete differential circuit 22 to which a signal ΔP proportional to the power variation in comparison with the effective power of  the generator is given to an automatic voltage regulator AVR via a limiter circuit  LIM for limiting the output of a system stabilizer. In such a way, a stabilizing  signal is obtained in the form of the combination of the speed variation signal and  the power variation signal, so shortage of each stabilizing signal can be compensated to increase the control characteristic and improve the stability.

Abstract: PROBLEM TO BE SOLVED: To optically couple an optical component with ease and high efficiency by arraying subordinate substrates by engaging one 2nd engaging mechanism selected out of engaging mechanisms with a 1st engaging mechanism. SOLUTION: The constitution of 2nd engaging mechanisms 112 and 122 and the fixation state of optical components 210 and 220 are so determined that when one of the 2nd engaging mechanisms 112 and 122 is selected, the optical axes of optical components 210 and 220 are different in height viewed from the surface of a common substrate 100A if the selected engaging mechanism is different. Then the 2nd engaging mechanisms 112 and 122 are provided and arrayed by being engaged with a substrate 110A and 120A (subordinate substrate) engaging mechanism 101 where optical components 210 and 220 are mounted, so that the optical axis heights of the optical components on the substrate varies. Consequently, the optical components mounted on the subordinate substrates 110A and 120A can precisely be adjusted in position at right angles (height direction) to the main surface of the common substrate 100A.

Filed: 1994-06-30
Abstract: PURPOSE:To remove an influence of a signal of an unnecessary signal source and remove an influence even if unnecessary signal sources are plural and the size of the signal source is changed so as to improve the defect detecting performance.

Abstract: PURPOSE:To prevent vanishing of a silicide layer, etc., due to oxidizing, oxygen plasma processing by covering the silicide layer, etc., with a protective layer having resistance against oxidizing or oxygen plasma processing for removing a resist mask. CONSTITUTION:An SiO2 film 6 and a borophosphosilicate glass (BPSG film) 7 are sequentially deposited on the entire silicon substrate 1.
