Abstract: PURPOSE:To obtain the method suitable to mass-produce the title crystal having excellent quality, homogeneity and reproducibility by a method wherein the resistance against the gas stream of the piping section, to be connected to each crystal growth chamber and branched from the main pipe part with which raw gas will be fed, is equally formed. CONSTITUTION:The first raw gas is fed to a main pipe section 11, the gas is branched to a dispensing tube part 13-i at a branching point 15, it passes through a gas introducing hole 4-i and introduced into a reaction tube 1-i. Also, the second raw gas is fed to the main tube part 12, brached to a distribution tube section 14-i at a branching point 16 and then it is introduced into a reaction tube 1-i passing through a gas introducing hole 5-i. The reaction-finished waste gas is exhausted from an exhaust hole 6-i. All of the geometric shape and the arrangement of the reaction tube 1-i are almost equally set, and the inner diameter and the length of the dispending tube part 13-i and the dispensing pipe part 14-i are set in such a manner that the resistance against the gas stream will be made equal. Through these procedures, the title crystal having excellent quality, homogeneity and reproducibility can be mass-produced.

Title: Apparatus for monitoring etching hole and trench
Inventor: NOGUCHI MINORU
IPC: H01L21/302
Filed: 1985-04-19
Abstract: PURPOSE:To enable monitoring of the size and shape of an etching hole and trench by providing photo-detector means for detecting a specific diffracted light among the diffracted lights reflected from a wafer, and abnormality detector means for detecting etching abnormality from the magnitude of contrast. CONSTITUTION:The laser beam applied onto a wafer 7 reflects, diffracts and interferes according to a regular pattern on the wafer 7, reaches onto a ground glass 27 through a window 6 formed in a low-pressure treatment chamber 1, and diffuses at the surface of the ground glass 27 to be drawn into a first photo-detector 28. On the other hand, the light specularly reflected at the surface of the wafer 7 is taken into a second photo-detector 32 through a half-mirror 26. The etching amount of an etching mask 60 can be monitored by the waveform detected by the second photo-detector 32, and the etching speed ratio can be monitored by comparing the result of the above monitoring with the etching amount of the hole and trench portion obtained from the waveform detected by the first photodetector 28. With this, abnormality in the size and shape of the etching hole and trench can be monitored.

Title: Interlock mechanism for control circuit connector in draw out type machine
Inventor: HASHIMOTO EISHIN
IPC: H02B11/133
Filed: 1994-03-29
Abstract: PURPOSE:To provide an interlock mechanism in which the connector of control line can not be removed when a machine is in the operating position and the machine can be pushed into the operating position only when the connector is connected. CONSTITUTION:When a machine body 1 is at an operating position, an interlock pin 15 strikes against an interlock plate 30 to block lowering of a slide plate 14 which thereby engages with a protrusion 7 of a connector 3 thus preventing removal of the connector 3. When the machine body 1 is a disconnecting position, the pin 15 does not strike against the plate 30 and thereby the slide plate 14 descends to release an engaging piece 7. When the connector 3 is drawn out along with a protrusion 8, a rod 13 advances and a pin 24 descends to interfere with the plate 30 thus blocking push-in of the machine body 1. When the connector 3 is connected, the pin 15 and the slide plate 14 are lowered to clear the front side of the engaging piece 7. Upon insertion of the connector 3, the slide plate 14 returns to engage with the piece 7 thus preventing removal of the connector 7. At the time of insertion, the protrusion 8 pushes a rod 23 to place the pin 24 on the plate 30 and then the machine body 1 is pushed into an operating position.
