Title: Phase shift mask and its production
Inventor: YOSHIDA AKIRA
IPC: G03F1/80
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a phase shift mask which suppresses the variation in the light intensity of transmitted light from all apertures and improve the uniformity of the sizes of transfer patterns by covering the side walls of the recessed parts of a photomask formed with the recessed parts as phase shift regions within a transparent substrate with light shielding films. SOLUTION: The side walls of the recessed parts 11 within the transparent substrate are A are covered with the light shielding film 4a (a). As a result, the transmitted light entering diagonally from the side walls of the recessed parts 11 is shielded by the light shielding films 4a of the side walls (b). Then, the light intensity distribution on a wafer is such that the light intensity distribution A of the transmitted light of the recessed parts 11 is equal to the light intensity distribution B of the transmitted light in the adjacent apertures (d). Consequently, the uniform sizes of the transfer patterns may be obtd. on the wafer and the improvement in dimensional accuracy may be obtd. even with the shift mask formed with the recessed parts 11 within the transparent substrate 1. The mass production yield of an LSI chip may, therefore, be considerably improved.

IPC: G11B7/00
Filed: 1989-09-28
Abstract: PURPOSE:To arrange a bit string to be formed on a master disk at a physically accurate position even if rotational jittering is caused by feeding the output signal of a rotary encoder connected to a master disk rotating motor back to a reference clock part to correct the frequency of a write information signal. CONSTITUTION:Since the input voltage is proportional to the output frequency at a voltage-to-frequency conversion part 107, the frequency of a corrected reference clock 108 is higher than that of a write reference clock 103 when the revolution of a master disk rotating motor becomes higher than the specified revolution.

Write information is generated from a write information generating part 109 in synchronization with th corrected reference clock 108 and outputted to the electro-optical conversion part of a master disk exposure device 202. The frequency of the write information signal is changed in accordance with the change in the revolution of the master disk rotating motor due to the rotational jittering in this way, and the bit string to be formed on the master disk is arranged at a physically accurate position.

Title: Semiconductor manufacturing apparatus
Inventor: KOBAYASHI TOSHIYUKI
IPC: H01L21/31
Filed: 1984-11-28
Abstract: PURPOSE:To improve uniformity of film thickness with a reaction gas concentration uniformed on a substrate, by providing with a supplying side pressure- equalizing chamber and exhausting side pressure-equalizing chamber in the reaction chamber. CONSTITUTION:Curtain gas 8 is supplied into a curtain gas supplying chamber 15 and is introduced into the reaction chamber through curtain gas supplying ports 15c. Reaction gas 7 is supplied into a reaction gas supplying chamber 14 and is introduced into the reaction chamber through a supplying port 14d of the supplying chamber 14. Exhaustion gas 9 consisting of the reacted gas and curtain gas is flowed into an exhaustion chamber 13 from an exhaustion port 13c, and is exhausted from the exhaustion chamber 13 outside the quartz glass tube 21. In this structure, since the blowing-out resistances of the gas 7, 8 at the respective supplying ports 14d, 15c in the supplying chambers 14, 15 are large, the pressure in the axial direction of the tube 21 becomes uniform. Owing to the taking-in resistance at the exhaustion port 13c, the gas pressure in the reaction chamber becomes uniform in the direction perpendicular to the gas flow so that concentration of the gas 7 over the substrate 4 can also become uniform.

Abstract: PURPOSE:To reduce the generation of electromagnetic noise and vibration noise of an AC chopper system by providing a voltage suppressing means to feed an applying voltage the crest value of which is suppressed at the initial stage of the starting of energization during the ON-period of a fan motor. CONSTITUTION:When a light emitting diode 17 emits light and a photo transistor 16 is in an ON-state, a fan motor 2 is not run. When the light emitting diode 17 is migrated from a light emitting state to a non-light-emitting state, the photo transistor 16 is changed from an ON-state to an OFF-state, and a capacitor 12 is gradually charged through a resistor 11 by means of voltages at both ends of a smoothing circuit 6. According to the change of the capacitor, an FET 10 is gradually migrated to an ON-state, and finally brought into a complete ON-state. In this case, the charging constant of the capacitor 12 is decided by a product of the resistance value of the resistor 11 and capacitance of the capacitor 12. A voltage applied on the fan motor 2 according to the change of the ON-state of the FET 10 is gradually changed from a value lower than the voltage value of an AC source 3 to a total voltage.
