Title: Spray processor
Inventor: KAWAHARA MASAAKI
IPC: G03F1/68
Filed: 1989-10-26
Abstract: PURPOSE:To maintain the uniformity of spraying by forming the base-side opening of an exhaust hole at an upper part to larger area than the opposite- side opening connecting with said opening. CONSTITUTION:The spray processing includes a base 2 where an object 1 of spray processing is mounted, a spray nozzle 3 which sprays liquid on the base 2, and a side wall which is arranged at the periphery of the base 2 and has plural exhaust holes 41 - 46. Then the openings of the exhaust holes 41 - 46 on the side of the base 2 are formed at the upper part to the larger area than the opposite-side openings connecting with said openings. Therefore, chemicals which are sprayed and reach the side wall are discharged from the exhaust holes 41 - 46 and never splashed onto the object 1. Consequently, a mask of excellent surface quality which has highly accurate pattern size can be manufactured at high yield.

Title: Method of forming phosphorus nitride insulating film
Inventor: FUJIEDA SHINJI
IPC: H01L21/318
Filed: 1990-10-19
Abstract: PURPOSE:To deposit a PNx film in excellent quality doing not damage to a semiconductor surface by a method wherein hydrazine in specified feeding ratio exceeding 20 to t-butyl phosphine is adopted as a material to be vapor grown at specified substrate temperature in hydrogen atmosphere. CONSTITUTION:Since no etching gas is contained in the material system under this constitution, no etching phenomenon will be observed on a substrate surface. When N2H4 feed is insufficient, P is liable to be excessive in a PNx film, that is, the value X is liable to be X<1.66 which be augmented by specifying the feeding ratio of hydrazine to t-butyl phosphine to exceed 20. The mixture of hydrogen in the PNx film can be restrained due to the high decomposition property and mutual reactivity of the t-butyl phosphine and hydrazine. At this time, carbon is apt to mix in the PNx film since the t-butyl phosphine is an organic phosphorus compound, however, this mixture can be restrained by the reaction step in the hydrogen atmosphere. Furthermore, the PNx film having the resistivity exceeding 2X10<14>OMEGAcm can be formed by specifying the substrate temperature to be at 350-600 deg.C.

Title: Active filter device
Inventor: OGIWARA YOSHIYA
IPC: H02J3/01
Filed: 1993-11-09
Abstract: PURPOSE:To make compensating currents flow through the zero-phase circuit of a transformer from a single-phase inverter by connecting the single-phase inverter to the zero-phase circuit of the three-phase four-wire type transformer and supplying the single-phase inverter with the zero-phase wave component of the higher harmonic currents of load currents. CONSTITUTION:Each-phase current flowing through load is detected by a current transformer CT, and mixed by a mixing circuit 2, and only tertiary zero-phase higher harmonic component is input to an active filter device 1 as command currents through a band-pass filter 3. A pulse circuit 12 for the active filter device 1 outputs a PWM pulse signal for control to a single-phase inverter 11 so that currents flowing through a neutral conductor N from the single-phase inverter 11 and command currents are brought to antiphase, and compensates a higher harmonic component flowing through the neutral conductor N. Accordingly, a fundamental-wave positive-phase voltage section is not added to the single-phase inverter 11, thus reducing the capacity of the single-phase inverter 11, then also scaling down a transformer Trh.

Title: Treatment apparatus
Inventor: AKUMOTO MASAMI
IPC: H01L21/68
Filed: 1988-11-07
Abstract: PURPOSE:To sharply reduce dust particles to be produced when an object to be treated is supported by using a pair of tweezers by a method wherein the tweezers capable of delivering the object to be treated are installed at each treatment unit, faces where at least three parts protrude from their plane so as to support the object to be treated can be vacuum-sucked in at least one part of the protruding faces. CONSTITUTION:A semiconductor wafer 22 is supported by three points of a first protruding part, a second protruding part and a third protruding part 50, 51, 52 on a pair of tweezers 23; since a contact area to the wafer 22 can be reduced considerably, it is possible to restrain a dust particle from being produced as low as possible during an alignment operation. In addition, when the semiconductor water 22 is vacuum-sucked and held on the tweezers 23, an opening part 53 for vacuum suction use is formed only at the third protruding part 52. Accordingly, a danger that the rear of the wafer is damaged by a pressure during a vacuum suction operation can be reduced sharply as compared with an apparatus where an opening part for suction use is formed over a prescribed length region; through this constitution, it is possible to solve a problem that the dust particle is produced.
