IPC: H01L21/822
Filed: 1991-02-04
Abstract: PURPOSE:To realize a two-layer polycrystalline silicon capacitor with high performance and also prevent a characteristic from deteriorating due to an invasion of phosphorus into an MOS region by a method wherein, after a non- doped polycrystalline silicon is formed on the surface of a lower electrode, it is heated to form an oxidized film on the surface of the non-doped polycrystalline silicon.

After a non-doped polycrystalline silicon 9 is formed on the surface of the lower electrode 4, it is heated. Thus, an oxidized film 6 is formed on the surface of the non-doped polycrystalline silicon 9. The phosphorus of the phosphorus-doped polycrystalline silicon 4 at forming the oxidized film 6 is scattered into the non-doped polycrystalline silicon 9, so that it is not evaporated in the gaseous phase. Thus, dispersion of an MOS threshold voltage is removed to obtain the MOS with a constant characteristic.

Inventor: KONUMA TAKESHI
IPC: H01L29/80
Filed: 1979-02-07
Abstract: PURPOSE: To improve the characteristic of FET by making the impurity concentration of the channel in the neighborhood of gate layer different from that of the channel in the neighborhood of depletion layer.  
     CONSTITUTION: The n epitaxial layers 12, 12' with specific resistances 0.2Ω, 1.5Ω and SiO 2  film 13 are laminated on the p-type Si substrate 11 and are isolated by the p + -layer 14. Next the p + -layer 15 and the n + -layer 16 that reaches the layer 12 are selectively formed in the layer 12'. Last the Al electrodes 17 are selectively provided. The impurity concentration of the layer 12 is greater than that of the layer 12', the gate layer 15 is formed in the layer 12'. Thus the gate capacitance can be reduced. Since the concentration of layer 12' is lower, the with standing voltage across the gate-source is higher, and because most drain current passes through the n-layer 12, low-frequency noise is decreased. Also, since a breakdown voltage in the neighborhood of the surface can be made higher to increase the concentration of the n-layer 12, g m  is also improved.

Title: Detector for scanning start position
Inventor: SENSUI KIYOSHI
IPC: G06K15/12
Filed: 1978-02-09
Abstract: PURPOSE: To obtain a detector for scanning start position which is not affected by the change of the detector output by installing the optical scanning part with two units of the adjacent photo detectors, the differential amplifier, two pairs of threshold amplifiers, the level conversion circuit and the logical product circuit each.  
     CONSTITUTION: When the scanning light moves from left to right as shown in the figure to photo detector 1 and 2, the output of differential amplifier 3 changes as a', b' and c'. Thus the waveform features the sine wave as shown in A. Now, it is supposed that the output of 3 varies as shown in B due to the intensity of the irradiation light arriving at element 1 and 2, the temperature characteristics of the element and other factors. In this case, however, both A and B feature the same timing to cross OV from the positive to negative regions. The output of amplifier 4 featuring threshold voltage VTH and VTH 2  features like C and D, and the output of inverse amplifier 5 featuring the TH voltage at OV becomes like E and F respectively. This signal passes through level conversion circuit 6 and 7, and its output features G and H at logical product circuit 8 with exactly same rise point of the signal. Thus, no effect of the output change of element 1 and 2 is given at all.

Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To provide good conductivity for a through hole part, improve soldering thermal resistance after moisture absorption, and prevent generation of conductivity failures due to thermal shock by constituting a dendritic copper powder and a binder resin having a specific average particle diameter and an apparent density. SOLUTION: A dendritic copper powder obtained by an electrolyte or the like in 1 to 25 micrometers in average particle size and 1.0 to 4.0g/cm<3> in apparent density and preferably a binder resin of 10 to 40wt.% with respect to the copper powder are composed. Due to this copper powder, since a contact area between the copper powders is large, the conductive resistance value is low, the surface is relatively hardly oxidized, and there is no jamming during screen printing. This blending quantity of the binder resin is suitable to contact between the copper powders, and in particular, use of resor-type phenol resin is preferable. As required, a solvent of glycol ether or the like, oxidation inhibitor, and dispersant or the like are added. This copper paste is heated and cured after being embedded in a through hole of a printed circuit board by screen printing.
