Granted: 2001-04-16
Abstract: PURPOSE: A method for detecting/initializing an extended memory unit through a VME(Versa Module Euro) bus is provided to extend the capacity of a memory of a unix system and use the memory by enabling a unix kernel to sense and initial an extended memory unit in case that the extended memory unit is mounted through a VME bus and used. CONSTITUTION: A value designated to an entry point of a bus error adjuster among ejection vector table items of a processor is stored in a specific memory area in order to detect the capacity of a memory of an extended memory board mounted to a unix system. After that, the entry point newly defined is stored in a relevant item of the vector table. A physical starting address is determined. A reading operation is repeatedly performed from the physical starting address determined. After the operation is terminated, it is sensed whether a bus error is generated. In case that the bus error is generated, the entry point of the bus error adjuster is restored in a relevant item of the vector table. After the size of the specific memory is estimated, the size is added to the size of a main memory device of the unix system.

Title: Particle removing apparatus of wafer rearface
Inventor: KANG HEE-SOON
IPC: H01L21/304
Filed: 1993-03-29
Granted: 1996-09-30
Abstract: The apparatus removes the contaminant abnormal particles aticking to the back side of the wafer to prevent a poor condition of the wafer. The apparatus comprises: a vacuum chuck(21) installed at the upper part of a support plate(1) to fix the upper face of the wafer by using a adsorbing force; a vacuum generator(22) driving the vacuum chuck(21); a vacuum tube(23) connecting the vacuum generator(22) to the vacuum chuck(21); a driver(30) moving the vacuum chuck(21) up and down, right and left; a contaminant particle remover(40) installed under the chuck(21) and including a circular brush(41) with a plurality of air holes(41a).

Title: 광분리증폭기패키지,광분리증폭기및신호감지방법
IPC: G01R15/22
Filed: 1993-06-04
Granted: 2002-06-28
Abstract: 본 발명은 아날로그 입력 신호에 대해 선형적인 저잡음 아날로그 출력신호를 발생하고 통상적인 8 핀 듀얼 인-라인 패키지(8-pin dual in-line package) 내에 용이하게 설치되는 광 분리 증폭기(optical isolation amplifier)를 제공하는 것이다. 광 분리 증폭기 패키지는 아날로그 입력 신호를 디지털 신호로 변환시키는 시그마 델타 아날로그 디지털 변환기(sigma-delta analog-to-digital(A/D) converter)를 구비하는 입력 칩을 포함한다. 시그마 델타 변환기는 신호를 정확한 광 복원부를 구비하는 분리된 출력 칩 상의 광 검출기로 광학적으로 전송하는 오프 칩 LED(off-chip LED)를 변조하도록 사용되어 전송된 신호를 재생한다. 또한, 디지털 아날로그 변환기는 출력 칩 상에 제공되어 디지털 신호를 아날로그 입력 신호에대해 선형적인 아날로그 출력 신호로 변환시킨다.

Title: Method and apparatus for eliminating short circuit portion in semiconductor elements
Inventor: MIDORIKAWA TAKAFUMI
IPC: H01L31/20
Filed: 1993-07-01
Granted: 1997-04-12
Abstract: The present invention aims to provide a highly reliable semiconductor element with high performance, and a fabrication method for such highly reliable semiconductor in excellent mass production. A fabrication method for photovoltaic elements comprises an electric conductor (301), semiconductor regions (302) and a transparent conductor layer (303), which are formed on a substrate. The shunt resistance in the semiconductor element is rendered 1x10<3> OMEGA cm<2> to 1x10<6> OMEGA cm<2> by forming a dielectric breakdown region (305) around a low resistive defective portion (304) after forming the electric conductor layer, the semiconductor regions and the transparent conductor layer on the substrate, and then selectively covering for insulation the defective portion with a cation or anion electrodeposition resin (307), or performing a forming treatment, after forming the electric conductor layer (or transparent conductor layer) and the semiconductor layers on the substrate, then selectively covering for insulation the defective portion with a cation or anion electrodeposition resin, and further forming the transparent conductor layer (or an electric conductor layer). <IMAGE>
