    摘要: First flash irradiation from flash lamps is performed on an upper surface of a semiconductor wafer supported on a temperature equalizing ring of a holder to cause the semiconductor wafer to jump up from the temperature equalizing ring into midair. While the semiconductor wafer is in midair above the temperature equalizing ring, second flash irradiation from the flash lamps is performed on the upper surface of the semiconductor wafer to increase the temperature of the upper surface of the semiconductor wafer to a treatment temperature. Cracking in the semiconductor wafer is prevented because the second flash irradiation is performed while the semiconductor wafer is in midair and subject to no restraints.

    摘要: A microwave plasma etching method and apparatus for performing substantially anisotropic etching to form micropatterns on IC substrates. A microwave power source creates a plasma from a gas with a relatively low pressure such as 10.sup.-3 to 10.sup.-4 Torr, so that the mean free path of the gas molecules exceeds the dimensions of the etching apparatus. A magnetic field is generated in a plasma generating chamber, a reaction chamber where in the substrate is mounted and a connecting chamber. The plasma discharge is enhanced by a cyclotron resonance magnetic field intensity corresponding to the frequency of the microwave power applied to the plasma chamber. The magnetic field creates a magnetic mirror which prevents the electrons in the plasma from entering into the reaction chamber so as to eliminate the generation of free radicals in which the reaction chamber which adversely affect the anisotropic etching ability.

    摘要: 633,346. Asymmetrically conducting resistances. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 30, 1946, No. 26160. Convention date, Feb. 22, 1943. Drawings to Specification. [Class 37] In a blocking layer cell of the selenium type having .a first electrode comprising a carrier plate on which a semi-conductive layer and a second electrode are mounted, the second electrode is coated with a layer of lacquer and the cell is then subjected to heating between 100‹ and 200‹ C. In the preferred method a galvanized aluminium carrier sheet coated with a carbon film has a layer of selenium applied to it, and small discs punched from the sheet are provided with small gold electrodes by sputtering. The discs are then sprayed with a solution of polystyrene, dried and heated in air to 170‹ C. for about half-an-hour. Specification 632,166 is referred to.
