Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To improve the controllability and repeatability of a process by installing a mechanism to keep monitoring the concentration of reactive gas in a chamber, and allowing the gas concentration to reach a value set by a mass flow controller before starting the process. SOLUTION: After a wafer 5 is placed in a chamber 4, nitrogen is introduced into the chamber 4 through a carrier gas pipe 2 to obtain a nitrogen atmosphere. Thereafter, hydrogen is introduced. When the interior of the chamber has been completely turned into a hydrogen atmosphere, diborane gas diluted with hydrogen is introduced through a reactive gas pipe 3. The concentration of the reactive gas is checked using a reactive gas concentration measuring instrument 20. When the concentration of the reactive gas reaches a specified value, a heating lamp 8 is turned on to heat the wafer and diffuse boron. This makes it possible to reduce deviations between batches, such as the sheet resistance and film thickness of wafers, to 1/3 or so.

Abstract: PURPOSE:To increase the diameter of a torsional coil spring and to smoothly execute an operation to open and close a lid mechanism of a tape by providing a cassette structure with a guiding part to be fitted with a torsion coil spring in a state offcentered to the revolving shaft of the lid mechanism. CONSTITUTION:The torsional coil spring 21 is fitted into the guiding part 14 having a central point (P) in the upper part position at the central point (O) of the lid revolving shaft 13A when the lid mechanism is held closed. The guiding part 14 rotates counterclockwise as well apart from an optical path 22 by the distant component of the eccentricity according to the counterclockwise rotation of the lid revolving shaft 13A when the lid mechanism is put into an open state from such state. Namely, the central point (P) of the guiding part 14 moves in the direction parting from the optical path 22 up to the position of the central point (Q). Then, the torsion coil spring 21 fitted in the guiding part 14 rotates eccentrically as well in the left direction parting from the optical path 22 according to the guiding part 14, i.e., the direction where the optical path 22 is not hindered. As a result, the closing of the optical path 22 does not arise even if the structure to increase the torque is adopted by increasing the diameter of the spring 21.
