Abstract: PURPOSE:To improve the crystallinity of a GaAs semiconductor by reducing the radius of curvature in a central section by thickening the film thickness of the peripheral section of the GaAs semiconductor. CONSTITUTION:A GaAs semiconductor 14 is crystal-grown on an Si substrate 12 in a GaAs semiconductor wafer 10. Film thickness is approximately 3.5mum an intended within a range of a radius of approximately 15mm from the center of the wafer 10 in the semiconductor wafer 10, but the film thickness of the GaAs semiconductor 14 is increased suddenly at the outside of said range.

Abstract: PURPOSE: To easily and accurately set the position of a register mark-detecting means by a method wherein the position data is set in response to the register mark forming position for different kinds of packaging bags, and then, the driving of a regulating mechanism is controlled. CONSTITUTION: A film width is input by a keyboard of a touch panel 22, and then, a distance dimension from the end of the film to a register mark forming position is input as the register mark position. By doing so, a CPU23 determines the position data which is equivalent to a moving quantity in response to the film width of each kind. Then, the position data is transmitted to a back-up RAM27 and stored. Then, the position data is output to a RAM25 and a motor controller 30 of a driving-control means 18a for a regulating mechanism. For this reason, a register mark-detecting means is moved in the direction which is orthogonal to the film transfer direction, conforming to a moving quantity which is input with a film end detecting position of a film side end position- detecting means as the origin, based on the position data corresponding with a register mark position.
