Title: Semiconductor photodetector
Inventor: OOUCHI HIROBUMI
IPC: H01L31/10
Filed: 1979-03-28
Abstract: PURPOSE: To provide a photosensor having large signal output and S-N ratio by forming a MOSFET switch making contact with a substrate at the source and the drain with a photodiode on a sapphire substrate.  
     CONSTITUTION: An n-type epitaxial layer, SiO 2  23, Si 3 N 4  24 and SiO 2  25 are sequentially laminated on a sapphire substrate 21, sequentially etched, and an n-type layer 22 is partially etched. The film 25 is removed, the exposed portion of the layer 22 is oxidized as a SiO 2  film 221, the film 24 is removed, and an opening 222 is perforated at the film 23. A gate oxide film 9 and a polysilicon gate electrode 6 are formed at the opening, B is diffused thereon to form a source 3 and a drain 4 thereon. The film 23 is then selectively removed, B is diffused thereon to form a shallow p-type layer 2 thereon. Thereafter, a reflection preventive film 26 and electrodes 7, 8 are attached thereto to complete it. Since the source and the drain are arrived at the substrate in this configuration, its junction capacity is remarkably reduced to increase the signal output and s/n ratio with high operating speed.

Abstract: PURPOSE:To enable a device of fine geometry by forming simultaneously a selectively oxidized region and a channel contacting region using a sidewall as a mask and by forming N<+> source region using the selectively oxidized region as a mask. CONSTITUTION:Impurities of inverse conductivity type are implanted into a well region 45 using as a mask a sidewall 51 formed on the sidewall part of a window 41 for diffusing impurities. A selectively oxidized region 53 is formed by oxidizing it selectively on the surface of the well region, which is exposed being not covered by the sidewall. At the same time, a contacting region 54 of inverse conductivity type is formed in the well region 45. Then, the sidewall 51 is removed and an impurity diffusing region 57 is formed by diffusing impuri ties of inverse conductivity type from the window 41 for diffusing impurities using the selectively oxidized region 53 as a mask. Thereafter, by a heat treat ment, a source region 58 is formed being altered from the impurity diffusing region 57. Therefore, there is no necessity to form patterns by mask alignments. Thereby, there is no necessity to consider positional discrepancies caused when aligning, and a device of fine geometry can be obtained easily.

Title: Mixer circuit
Inventor: TAKAHASHI HIROSHI
IPC: H03D9/06
Filed: 1989-02-16
Abstract: PURPOSE:To obtain an excellent conversion loss characteristic even when an IF signal frequency is high by connecting 2nd and 3rd MS lines having a prescribed electric length to other terminal of a 1st microstrip line having a prescribed electric length and connecting to a diode. CONSTITUTION:A 2nd microstrip line 7 has an electric length theta2, in pi(n-1)/2 radian having a frequency fo between an RF signal frequency fo, and an Lo signal frequency fLo and the impedance at the frequency fo when viewing a connecting point B between the 1st microstrip line 8 and the line 7 toward the line 7 is an open impedance. Thus, the line 7 gives almost no effect to the RF signal and the Lo signal. Suppose that the impedance when the frequency fIF is comparatively high has an inductive reactance, the electric length theta1 of the line 8 and the electric length theta2 of the line 7 have a relation of theta1+theta2=npi radian, and since an electric length theta3 of a 3rd line 6 is set so that the impedance when viewing the line 6 from the point B is an open impedance, the increase in the conversion characteristic is suppressed. Moreover, the characteristic impedance of the line 7 is maximized at the higher fIF.
