Filed: 1989-04-11
Abstract: PURPOSE:To enable a cut part to be automatically removed thereby enabling the development cost to be reduced while the delivery time to be assured by cutting down the required term by a method wherein all the patterns are expanded by half value of the minimum width posing a problem in manufacture of a U-shaped cut and then the expanded patterns are contracted by the said value. CONSTITUTION:Within the patterns on a piece of photomask used for manufacture of an LSI, all patterns 2-4 are extended by half value of the minimum width posing a problem in manufacture of a U-shaped cut 1 per respective patterns 2-4 forming an island while the expanded patterns 5 are contracted by the half value of the minimum width posing the problem in manufacture of the said U-shaped cut 1 on respective patterns 2-4 forming the objective islands of the said expansion. For example, assuming the minimum width posing the problem in manufacture of the U-shaped cut 1 to be 4mum, the patterns 5 can be formed by expanding the respective patterns 2-4 forming an island. Likewise, patterns 6 can be formed by contracting respective islands 2-4 by 2mum opposite to the patterns 5.

Abstract: PURPOSE: To obtain, through Czochralski process, a Si single crystal uniformized in impurity concentration distribution in its radial direction. CONSTITUTION: When a Si single crystal is pulled up from a Si melt added with Ga or Sb through Czochralski process, element(s) capable of increasing the thermal expansion coefficient of the melt in the vicinity of its melting point (at least one kind of element selected from between B and P) is further added to the melt. As the result, agitation of the melt just under the growth interface can be promoted, and as the Si single crystal is pulled up from the melt uniformized in impurity concentration distribution, the Si single crystal uniform in impurity concentration distribution in its radial direction can be grown.

Filed: 1982-06-02
Abstract: PURPOSE:To prevent any return flow of the intake air which is apt to occur at a low speed of an engine by disposing a reed valve and a throttle valve in a main suction passage and in an auxiliary suction passage, respectively to encourage swirl of sucked air at a low load run thereof. CONSTITUTION:At a low load run of an engine with the first throttle valve 40 almost the fully closed position, a negative pressure which is detected by a load detecting port 76 is intense, on account of which a diaphragm 64 is pulled toward a negative pressure chamber 70 regardless of the speed of the engine so as to open the second throttle valve 60. Since a reed valve 56 is provided with the moderate trend of recovery, suction air passes through the auxiliary suction passage 42 at a low speed run to generate intense suction swirl inside a combustion chamber 16. At an intemediate load run, the negative pressure of suction air from a load detecting port 76 and Venturi negative pressure from a revolution seed detecting port 78 act together in the negative pressure chamber. At a high load run with the first throttle valve 40 almost in fully opened position, the negative pressure of suction air is weak, on account of which the second throttle valve 60 is opened and closed by the Venturi negative pressure.
