Patent JP-H02298038-A (JP)
Title: Semiconductior device and its manufacture
Inventor: DEKKER RONALD
IPC: H01L21/32
Filed: 1990-04-04
Abstract: PURPOSE: To increase the early voltage of a semiconductor device by reducing the intrinsic base-collector capacitance of the device by providing an additional region below extrinsic sub-areas, so that the additional area can superpose depletion areas of second p-n junctions upon a depletion area of a first p-n junction, when the first and second p-n junctions are reversely biased in one operation mode. CONSTITUTION: In a second device area 20 of one conductivity formed in the relatively lowly doped sub-region 12 of a first device area 10 of the opposite conductivity, an intrinsic sub-region 21 which forms a first p-n junction 22, together with the sub-region 12 and extrinsic sub-region 23 and 24 which form second p-n junctions together with the sub-region 12 around the area 21 are provided. In addition, a third device region 30 of the opposite polarity is provided in the region 21, and at the same time, an additional area 62 is provided below the regions 23 and 24.  Since the region 62 expands a depletion regions 250 of the second p-n junctions 25 to the bottom side of the emitter region 30 and superpose the regions 250 upon the depletion region 220 of the first junction by working to expand the regions 250, when the junctions 22 and 25 are reversely biased in one operation mode of a semiconductor device, the intrinsic base- collector capacitance of the semiconductor device can be reduced effectively.

Title: Encapsulation die for semiconductor device
Inventor: TANIURA TAKASHI
IPC: B29C45/26
Filed: 1989-04-06
Abstract: PURPOSE:To enhance the adhesion of a lead frame and a die and to suppress thin and thick burrs due to the leakage of a resin by respectively interposing heat-resistant elastomers on the pressure holding surfaces of upper and lower dies directly brought into contact with the lead frame. CONSTITUTION:Flat plate-shaped heat-resistant elastomers 4 are respectively provided to the pressure holding surfaces 7 adjacent to the cavity part 5 of the upper and lower dies 1a, 1b of an encapsulation die and the lead frame 2 connected to a semiconductor element 3 electrically is pressed by this mold. At this time, the pressing of the lead frame by the encapsulation mold is performed through heat-resistant elastomers 4 and metals are not brought to a mutual direct contact state. The heat-resistant elastomers 4 are formed, for example, by using silicone rubber and closely adhered to the lead frame to make it possible to embed the unevenness of the surface part of the lead frame. This unevenness is generated because the lead frame is prepared by punching processing and the surface of the lead frame sag in the vicinity of a processed part by shearing force and burrs protrude from the rear of said frame. Since the heat-resistant elastomers 4 are pressed to be closely adhered to the surface of the lead frame, the leakage of a resin is eliminated.

Title: Photodetector
Inventor: FUJIWARA ICHIRO
IPC: H01L31/107
Filed: 1988-04-13
Abstract: PURPOSE:To restrain an edge breakdown, obtain uniform multiplication in a light receiving surface, and make it possible to control the width of a multiplication region so as to be optimum, by selectively forming two semiconductor layers of high concentration carrier just under the light receiving surface. CONSTITUTION:On an N-type InP substrate 1, the following are continuously grown; an N<-->-InP layer 2, an N<-->-InGaAs layer 3, an N<->-InGaAs layer 4 and an N<-->-InP layer 7. By implanting Si from the surface of the region 7, an N-InP layer 5 and an N<->-InP layer 6 are selectively formed at a 2-2.5mum deep position. After an SiO2/SiN film 10 is stuck, an SiN anti-reflection film 9 is formed on a light receiving surface. Since a layer of high concentration carrier is formed just under the light receiving surface, yield voltage can be made low in the light receiving surface, and high in the edge part of a main junction 12. Thereby, edge yield can be restrained, and uniform avalanche multiplication can be obtained in the light receiving surface. Further, since electric field is sharply decreased in the region 5, the multiplication region can be controlled by the thickness of the region 6, and the multiplication region can be controlled so as to have the optimum thickness.

Abstract: PURPOSE: To improve the accuracy in treatment in a surface treating apparatus by manually running the treating apparatus once in accordance with desired steps while processing conditions are being visually observed by a surface treatment engineer and by making a program in an automated manner.  
     CONSTITUTION: Switches 19, 27 of a running operation board 18 are manually changed over by a surface treatment engineer. Then, a motor 5 is started by a manual switch 28 through a traversing motor driving device 14 to traverse a carrying device 1 to a desired processing tank. The distance over which the carrying device 1 is traversed is input to a rewriting circuit 25 by way of an encoder 6, and when the engineer considers necessary, such data are stored in a memory circuit 26 to rewrite a program. Similarly, an elevating motor 13 is started by means of a manual switch 20 to lift or lower a transporting frame 16. Again, when the engineer considers necessary, this action is input to the memory circuit 26. If the whole processes for rewriting the program data are completed, program controlling is performed.

Abstract: PROBLEM TO BE SOLVED: To provide a paper carrier tape for chip parts which eliminates troubles brought by fiber of paper while chip parts are charged in the carrier and has a strength enough to withstand the high speed running of an automatic charging device. SOLUTION: In a paper carrier tape 1 having a thickness to contain chip parts, through holes 2 and feeding holes 3 of the tape are punched out by a metal die. The periphery of the through holes 2 of the paper tape 1 is coated with an adhesive by rotation of a rotary brush. The adhesive applied on the through holes 2 penetrates to the nearby position of the inside walls of the holes 2 and forms a penetration layer 11 of the adhesive. Thereafter the adhesive is dried. In this way, since the penetration layer 11 of adhesive is formed on the inside walls of the through holes 2, fibers generated when the through holes 2 and feeding holes 3 of the paper carrier tape 1 are punched out are fixed to the inside walls of the through holes 2 by the adhesive.

Abstract: PURPOSE:To make the measured value accurate when relatively pure water is measured by providing a network body having small mesh at the sample sucking port of a measuring cell, and preventing the sucking of bubbles and relatively large grains in a sample to be measured when the sample to be measured is sucked. CONSTITUTION:A measuring cell 7, a wiper 9, a light source lamp 10 and a light receiving cell 11 are contained in a casing 12 of a detecting head 1. A network body 22 is provided at a sample sucking port 8 which is opened at the lower part of the measuring cell 7. Solid matters having the large grain sizes such as sand and dust in a sample to be measured which is sucked through a sample sucking port 8 are filtered through the network body 22. Thus the turbidity which is larger than the actual turbidity of the relatively pure sample is not measured because the following phenomenon can be prevented: sand, other solid matters, bubbles and the like which are not mixed uniformly in the sample itself are sucked into the measuring cell 7.

Abstract: PURPOSE:To enable heat in the upper part to be fed to the lower part without wastingly consuming energy such as electric power by a method in which a steam generator is connected with a liquid trap tank and a differential pressure drive valve is provided to a communication tube through which steam in the generator is introduced into the liquid trap tank. CONSTITUTION:When low-temperature working liquid 9 continues to flow into a liquid trap tank 6, the inside of the tank 6 is cooled, the internal pressure is lowered, and the difference of pressure between a generator 1 and the tank 6 becomes greater. The force to be applied to a closing plate 14 by the pressure difference becomes greater. A spring 15 is compressed to make a differential pressure drive valve 13 open state, and the vapor in the generator 1 is introduced through a communication tube 11 into the tank 6. When the generator 1 is connected to the tank 6, the pressures of both become equalized, and the liquid 9 in the tank 6 set above is refluxed under its own weight to the generator 1. When the pressure difference between the generator 1 and the tank 6 becomes smaller, the spring 15 is restored to its original length to make the tube 11 closed state and the liquid 9 is sent under pressures from the generator 1 through the heat exchanger 3 to the tank 6.
