Title: Manufacture of semiconductor device
Inventor: NAMURA ITARU
IPC: H01L21/3205
Filed: 1986-05-16
Abstract: PURPOSE:To detect the end point of the selective oxidation of a polysilicon film by implanting the ions of an impurity having either conductivity type to one part of a monitor pattern section in the polysilicon film and visually observing the formation of a stepped section on the interface of an impurity implanting section and a section, to which the impurity is not implanted, in thermal oxidation. CONSTITUTION:A polysilicon film 12 is grown onto an oxide film 11, and one part of the film 12 is used as a monitor pattern section 13. A resist film 14 is patterned so as to expose one part of the monitor pattern section 13, phosphorus ions are implanted, and a section 15, to which an impurity is doped, and a section 16, to which the impurity is not doped, are shaped into the polysilicon film 13. The resist film 14 is removed, an silicon nitride film 17 grown on the whole surface is patterned so as to expose the monitor pattern section 15, and the whole is thermally oxidized. Since the section 15, to which P<+> is implaned, is oxidized at a rate faster than the section 16, to which P<+> is not implanted, a stepped section 18 is formed between the section 15 and the section 16. Accordingly, the complete end of selective oxidation can be detected by the presence of the stepped section 18.

Abstract: PURPOSE:To execute a crystal growth operation by which a growth speed and a quality of a crystal are little dependent on a place by a method wherein a throttle part which is long and flat along a width direction of a substrate on which a compound semiconductor thin film is grown and a guide part which guides a reaction gas through a gap becoming narrow toward a downstream part are installed at an introduction tube used to guide the reaction gas up to the upper part of the substrate and a susceptor which has been housed in a specimen-mounting chamber is turned. CONSTITUTION:A mixed gas of TMG(trimethylgallium), TMA(trimethylaluminum), DEZ(diethyl zincate) and H2, which has been guided by a first gas tube 28, and a mixed gas of NH3 and H2, which has been guided by a second gas tube 29, are mixed near exits of these tubes; this mixed reaction gas is guided to a specimen-mounting chamber 21 by using a liner tube 12 and is passed through a gap formed between a sapphire substrate 50 and an upper-part tube wall 24 of the liner tube 12. At this time, a stream of the reaction gas on the sapphire substrate 50 is made uniform in a Y-direction by an action of a throttle part at a position A and becomes a layer stream which has been made uniform also in an X-direction by an action of a guide part by the upper-part tube wall 24 covering the sapphire substrate 50. In addition, since the substrate 50 is turned, a good-quality crystal, of a compound semiconductor, which is little dependent on a place can be obtained.

Title: Gate pulse generator
Inventor: NIIMURA TERUMI
IPC: H03K12/00
Filed: 1978-09-08
Abstract: PURPOSE: To use only one operational amplifier and make the relation between a control signal and a turn-on phase angle linear, by providing an operational amplifier which starts the integration of a constant input current in response to a signal from a zero point detector.  
     CONSTITUTION: A sine-wave AC voltage is applied to the zero point detector 130 to produce a rectangular-wave signal. The integrating action of the operational amplifier 122 is started at the time of falling of the rectangular-wave signal. The resistance ratio of a positive input resistor 120 to a negative input resistor 119 for the control signal Vi to the operational amplifier 122 is equalized to that of a voltage dividing resistor 121 to a bias resistor 114 to keep the input current to the operational amplifier 122 constant. The voltage of the control signal is altered to change the phase of pulse generation. Thus, integration, resetting and comparison can be effected by only one operational amplifier, and the relation of the control signal to the turn-on phase angle is made completely linear.
