Title: Gas sprayer for etching apparatus
Inventor: BROWN WILLIAM
IPC: H01L21/3065
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To minimize the recombination of reactive species by placing a shroud hanging down from a converging collar near a wafer chuck to reduce the effective passage vol. for feeding the reactive species to workpieces, and setting holes of a gas feed conduit, so as to uniformly spray the species over a wafer. SOLUTION: A gas-feed conduit 28 is supported with a converging collar 32 in a chamber 10, and a lip 46 is provided round the collar 32 to mount and position it on a shelf 36. A shroud 27 hangs down from the collar 32 very near to a wafer chuck 40 for minimizing the effective passage vol. of reactive species running to workpieces. The feed pipe 28 has holes 25 turning to the wafer chuck in the process chamber and two covers 34 at both sides to fill up the gap round the collar 32, thereby making smaller the vol. in the collar 32 than that of the chamber 10. This minimizes the recombination ratio of the species and increases the etching rate.

Inventor: MIYAMOTO TAKASHI
IPC: H01L23/495
Filed: 1980-10-01
Abstract: PURPOSE:To enable the connection of a lead to a terminal with high reliability even if a substrate is deflected by forming two or more plastically deformed parts at one lead at the connection of the lead to the terminal. CONSTITUTION:When bumps 2 on a semiconductor chip 1 are respectively connected to connection terminals 6 via leads 4, two plastically deformed parts 7, 7 are formed at one lead. In other words, pressure and supersonic wave are applied to the near side of the electrode of a semiconductor pellet 1 under weak condition and are applied to the far side under strong condition, thereby forming plastically deformed parts 7, 7 and bonding them. In this manner, since the optimum condition can be obtained at the high deflection of the substrate 5 at the near side of the electrode, and can also be obtained at the low deflection of the substrate at the far side f the electrode, the reliability of the connection can be enhanced as a whole.

IPC: B65H7/18
Filed: 1991-06-10
Abstract: PURPOSE:To eliminate the need for rotational operation of a picture drawing means so as to improve the printing efficiency by providing a paper supply cassette selecting means for selecting a paper supplying location which conforms to the format of a document to be printed, in a printing device. CONSTITUTION:One of plural paper supply cassettes 131 of a laser printer 130 is selected through a printer interface 118 by a paper supply cassette selecting means 113 based on paper size, format, paper supply location stored in a printing information storage means 112. A picture drawing means 115 converts drawing information stored in the storage means 112 into picture information to store it in a negative memory 117, that is, when the picture information is related to characters, the picture drawing means reads dot information which corresponds to character code from a font ROM 116 to convert the information into drawing size, and then permits the dot information to be drawn at the drawing location of the negative memory 117. Thus, since the most suitable cassette which corresponds to the format of a document can be out of plural cassettes, there is no need for the picture drawing means to draw a picture while it is being rotated, and thus the printing efficiency is improved.

Title: Closure structure of holder for insert molding of transponder
Inventor: SUGIHARA SATOSHI
IPC: B29C41/20
Filed: 1995-06-05
Abstract: PURPOSE: To prevent the damage of a transponder by housing the transponder in the housing recessed part of a holder main body to close the recessed part by a cap and cutting off the inside and outside of a holder at two places of an adhesion surface on an inner diameter side and an adhesion surface on an outer diameter side to prevent the inflow of a resin into the holder at a time of insert molding. CONSTITUTION: A transponder 12 is housed in the housing recessed part 22 of a holder main body 20 and the recessed part 22 is closed by a cap 21. The holder 19 having the transponder 12 housed therein is arranged to the holder attaching hole of a key main body. At this time, the key main body is positioned at the central part in the width direction of the holder 19 by a flange part 25. Subsequently, the key main body having the holder 19 set thereto is housed in a mold to start insert molding. Since the inside and outside of the holder 19 are cut off at two places of adhesion surfaces 28, 30 on inner and outer diameter sides, a resin does not flow in the holder. Since the outer end surface 21a of the cap 21 is expanded in an almost spherical shape, the adhesion degree of the adhesion surface 30 on the outer diameter side is enhanced.
