Granted: 1991-04-03
Abstract: The valve for remotely controlling the water flow is actuated by a DC  motor  (4)  whose  rotor  coil  is  electrically  powered according to the signal detected in a sensing  device.  The  water flow valve comprises a body (1) having first and  second  chambers (7,8), a diaphram (6) partitioning the two chambers and  a  signal control circuit connected to the rotor coil (4b). The rotation  of the  DC motor  output  shaft  causes  a  cam  (14)   to   operate micro- switches (S1,S2) for opening or closing a water  inlet  port (9) connected to the first chamber, within  which  water  pressure difference occurs to cause to open or lose the water flow valve.

Abstract: A sealable contamination proof container package bottom and top for storing and transporting a plurality of substrate or wafers in a robotic wafer carrier. The package bottom includes four sides, a continuous vertical surface for tape sealing surrounding the four sides, a lip positioned on a vertical edge, opposing hook latches on opposing sides, opposing hand grip recesses on the opposing sides and a raised bottom surface for package stacking. The package top includes four sides, a continuous vertical surface for tape sealing surrounding the four sides, a lip positioned on the vertical surface, opposing hook catches on the opposing side, a top surface with raised stacking surfaces, and two rows of wafer support springs positioned on bars on the underside of the top surface. The package top and bottom halves provide that the robotic wafer carrier mates between the package top and package bottom with the wafers or substrates in the carrier. The package top and bottom mate with the upper lip engaged with the lower lip, and the catches of the top engage with the latches of the bottom. The package halves are designed in such a fashion as to prevent wafer or substrate damage upon opening, in that the top package half is moved in a direction coinciding to the plane of the wafers or substrates with respect to positioning of the catches and latches on the package side. Appropriate sides of the package top and bottom are plumb with each other providing for a flush perimeter for ease of taping. The raised top portion of the top package half and the recessed bottom of the bottom package half provides for stacking of like packages. In an alternative embodiment, opposing rows of articulated cantilevered horizontal arms with centering V grooves on each end for engaging a wafer, disk or substrate extend inwardly from the edges of an arced top surface in the package top.

Abstract: 본 발명은 현지 칩마운터에 사용되는 칩공급장치인 카세트는 테이핑된 칩만을 사용하게 되어 있으나, 실린더형 칩 등을 테이핑하지 않고 그대로 공급할 수 있도록 한 칩공급용 개량카세트에 관한 것으로, 현재 사용되는 카세트(1)에 다수개의 롤러(2)(2`)및 (3)(3`)와 타이밍벨트(4)(5)를 장착시키고 일측에 칩공급부(30)를 형성하여 현재 구동되는 부위와 연결시켜 칩을 테이핑하지 않고도 일정하게 공급될 수 있도록 하므로서 테이핑 작업시간 및 테이핑자료 등을 절감할 수 있는 칩공급용 개량카세트이다.

Abstract: The punch-through characteristics of a PMOS transistor is improved by using the method to forming shallow junction-impurity diffusion layer. The method comprises the steps of; (A) injecting P-type dopant on a gate isolating layer and gate electrode region with certain depth; (B) forming side wall spacer on a side wall of a gate electrode; and (C) forming N-type impurity diffusion region by injecting N-type dopant.
