Abstract: PURPOSE:To attain the jumping completion at a purpose position by specifying a period up to the jumping completion in accordance with the period up to pass through a spot determined beforehand for the scanned track and the period to pass through the intermediate point of two tracks thereafter. CONSTITUTION:After a scanning point starts the jumping, the period up to the completion of jumping after an intermediate point passes is determined in accordance with a period (period until the output of a track detecting circuit 87 is inverted) up to the moment to cross a track scanned before a jumping is started and a period (period until the output of an intermediate point detecting circuit 85 is inverted) up to the moment to pass through the intermediate point of two tracks thereafter. Thus, even when the scanning point is controlled to a position away from the track, the jumping is completed at the position which is the purpose always, and therefore, an always stable jumping can be executed.

Title: Coating method for stepwise difference
Inventor: MOGAMI TOORU
IPC: H01L21/3205
Filed: 1984-05-04
Abstract: PURPOSE:To obtain a flat conductive film over the aperture of a steep side surface by a method wherein the ratio of the coating speed of a conductor film adhered to the flat Si substrate surface in the aperture of an insulation film, to the coating speed of said film to the flat surface on a stepwise difference is controlled by adjustment of coating conditions of substrate bias voltage and so on. CONSTITUTION:A flat Su substrate 201 is coated with a CVDSiO2 film 202, and an apeture (h) is formed. When an Al film 203 is ion-plated by biasing the substrate at about -5kV, neither micro cracks in the aperture nor grooves along the step bottom in the substrate 201 generates. Next, an Al film 205 is formed by biasing the substrate at about -30kV with the result that the Al coating speed on the flat surface 204 in the aperture is about twice that on the flat surface on the hole, step, when an almost flat Al film can be obtained. This manner enables film coating and flattening at the same time in fine apertures in the same vacuum system by using ion plating and can prevent wiring step cuts.

Filed: 1978-07-24
Abstract: PURPOSE:To obtain remarkably improved accuracy and speed by increasing the relative transfer speed of electrodes for a work, when the work comes to the corner part processing in the condition when the electrodes are relatively inclined against the work. CONSTITUTION:When the work is processed with inclination at its center at the wire-cut discharge processor for four axis control taper cut, the relative speed between the wire electrodes 5 and the work 1 is zero, and the relative speed increases as the processing comes close to the top surface of the work 1.
