摘要:
A microwave plasma treatment apparatus comprises a plurality of auxiliary magnets arranged around the periphery of a plasma formation chamber. A plurality of auxiliary magnets are disposed along the circumference of the plasma formation chamber while a plurality of auxiliary magnets may also be arranged in the axial direction of the plasma formation chamber. Also, the magnetic poles of every auxiliary magnet are respectively reverse in polarity to the adjoining magnetic poles of an auxiliary magnet(s) disposed adjacent thereto either along the circumference of the plasma formation chamber or in the axial direction thereof. This enables the whole high-density plasma to be substantially uniform throughout the inside of the plasma formation chamber.
摘要:
A microwave plasma etching method and apparatus for manufacturing electronic devices such as transistors. The method includes the steps of forming a stream of plasma from a processing gas within a plasma formation chamber by using an electric field produced by a microwave and an electron cyclotron resonance phenomenon produced by a magnetic field perpendicular to the electric field, and processing a substrate surface by locating it at the electron cyclotron resonance point and exposing it to a radiation of the plasma stream. The apparatus has a plasma formation chamber, a microwave introducing device connected to the plasma formation chamber, a magnetic field applying device for producing a magnetic field perpendicular to an electric field produced within the plasma formation chamber, and a gas introducing system for introducing a processing gas into the plasma formation chamber. A substrate holder is provided within the plasma formation chamber for holding a substrate at a resonance point of the electron cyclotron resonance phenomenon exhibited by the introduced microwave and applied magnetic field where the magnetic field has a particular strength.

摘要:
An adaptive type compression method for a color image in which each sequence of picture elements obtained by combination of sum-difference transformation with DPCM is compressed by being multiplied by an adaptive zonal filter. The sum-difference transformation is used to simplify transformation of the image into a spatial frequency zone. The zone filter characteristic is adaptively selected according to a predetermined transmission bit rate (compression rate). Further, this zonal filter characteristic is set so as to correspond with luminance and color difference signals. According to this method, image information to be recorded can be arbitrarily selected and distortion of the image at compressing and reproducing can be eliminated.

A shaded picture signal processing system and method which produces recorded pictures of high quality with a small number of gradation levels with the resolution of the picture maintained nearly unchanged. False contours appearing as quantization distortion are removed by dispersing noise of equal magnitude to the false contours throughout the whole picture or a specified portion of the picture so that the false contours cannot be detected by the human eye.

摘要:
An adaptative quantizer for use with color images separates each color component for separate quantization and breaks up the input image into a plurality of blocks. A quantization characteristic determining unit determines the characteristic to be used for a given block according to the distribution of quantization level values obtained when an estimation error in a preceding block is quantized according to a particular quantization characteristic. The characteristic may be changed when the distribution of quantization level values is smaller than or exceeds given threshold values.
