Title: Semiconductor device and manufacturing thereof
Inventor: MURAKAMI YOSHINORI
IPC: H01L29/78
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device with a fixed potential insulating electrode in a groove, wherein a shallow source region is realized, and the semiconductor device is satisfactory in transistor characteristics. SOLUTION: A shield film 30 is provided, a contact hole which has been conventionally single and located in an region comprising a source region 3, a fixed potential insulating electrode 6 and a source electrode is turned into discrete contact holes 23 and 24, and the source region 3 is formed after the fixed potential insulating electrode 6 has been formed, whereby the source region 3 can be made shallow. Therefore, a groove for the fixed potential insulating electrode can be made shallow, so that a semiconductor device of the constitution can be lessened in channel resistance and improved in current amplification factor.  Furthermore, the groove becomes shallow, and the gate region which is usually made deep so as to protect the edge of the fixed potential insulating electrode against a drain electric field can be made shallow, so that a semiconductor device limited in cell size by lateral diffusion can be reduced in size and improved in various characteristics.

Title: Vibration pickup microphone
Inventor: SATO FUMINORI
IPC: H04R1/00
Filed: 1994-07-20
Abstract: PURPOSE:To prevent the influence of what is called touch noise caused by the rubbing of a case on skin and the shaking of a leader line, in a bone- conduction microphone. CONSTITUTION:Inside a case 1, a weight plate 3 is supported via cushion material 2. On one surface of this weight plate 3, an element 5 for vibration sensing is mounted by a cantilever structure. On the multi-surface of the weight plate 3, a contact 6 is mounted. The vibration transmitting from the contact 6 to the weight plate 3 is transmitted to the element 5 via the weight plate 3. Because the element 5 is mounted via the weight plate 3 and the weight plate 3 is supported on the case 1 by the cushion material 2, the vibration from the side of the case 1 is absorbed by the cushion material 2 and does not affect to the element 5.

IPC: G01N21/88
Filed: 1991-07-30
Abstract: PURPOSE:To remove noise effectively from the photo-receiving signal. CONSTITUTION:A specimen 100 is irradiated with a laser beam laterally, and the light over a slit released upward is received by a TV camera 20. Therein the specimen 100 moves in the direction perpendicular to the laser beam. The released light over the slit obtained in association with this movement is added at each photo-receiving position, and noise component is determined. That is, noise at each photo-receiving position should remain without change even with moving specimen 100, and noise can be sensed from the adding result. Eventual noise is removed from the sensing results, and information associate with change in the specimen structure is obtained.

Title: Separating conveyor device for semiconductor device
Inventor: AOKI HIDEJI
IPC: B65G47/08
Filed: 1988-07-29
Abstract: PURPOSE:To obtain a conveyor capable of separating accurately without damaging a semiconductor device by holding the specific number of the semiconductor devices and separatively conveying them by the air pressure from a nozzle. CONSTITUTION:In the overlapped state, a presser pin 13 is first driven by the command of a driving means 20 so as to hold a semiconductor device 1 before separation together with an under rail 11. In this state, the compressed air is fed into a nozzle 111 so as to attempt to separate the semiconductor device 1 to be separated. However, the semiconductor device 1 to be separated cannot be separated due to being pressed by the semiconductor device 1 before separation. When such state is detected by means of a detecting means 21, the presser pin 13 is returned to the origin by the further command of the driving means 20 and a thrust pin 14 is driven instead so that the semiconductor device before separation can be lifted onto the surface of an upper rail 12 and held thereon. In such state, the overlap between burs 1a, 1b is released, and the compressed air is refed into the nozzle 111 so as to separate only the semiconductor device 1 to be separated.

Title: Base band signal changeover device
Inventor: KONDO MASAJIRO
IPC: H04B1/74
Filed: 1989-07-24
Abstract: PURPOSE:To eliminate the need for a measuring instrument for adjustment and to reduce the adjustment time by detecting a phase difference of a base band output signal, and varying automatically the delay of the active side or the standby side so that the phase difference is decreased to such degree that switching is attained without missing bits. CONSTITUTION:When a high speed switch 12 selects the position of the active side with an output signal of a switching controller 14 and a phase difference between active standby bipolar output signals is 1/4 bit or over, a phase comparator 2 outputs an H level phase error control signal to a control signal switch 1. The switch 1 selects the position of the standby side with an output signal of the switching controller 14 and the output of the phase comparator 13 is sent to a delay circuit 9 of a standby side digital signal processing section 4. A delay circuit 9 retards the data of the standby side by 1/8 bit each automatically, and when a phase error control signal reaches an L level, the delay at that time is stored. No bit is missing in this state even when the high speed switch 12 is selected from the active position into the standby position.
