Abstract: A winding roll presser device that presses a winding roll by the entire width thereof, the winding roll being formed by a reel spool and a long material wound therearound, said device includes a plurality of rotational rolls arranged in parallel with one another in the width direction, a belt tensely wound so as to cover the plurality of rotational rolls, a first drive unit for moving the belt from a stand-by position so as to bring the belt into contact with the winding roll, and a second drive unit for pressing the winding roll with a straight part of the belt.

Abstract: A lower electrode, a first inorganic insulating film of SiN, and an organic insulating film of polyimide are formed on a GaAs substrate serving as an underlie, in this order. The organic insulating film is selectively etched to form a capacitor opening. A second norganic insulating film covering the surface of the organic insulating film and the bottom and side wall of the capacitor opening, and an upper electrode are formed. As the selective etching of the organic insulating film, wet etching may be used for simplifying manufacturing processes. Alternatively, dry etching may be used for improving etching accuracy. The organic insulating film 4 may be formed by a multi-layer film so that a circuit can be formed across multi-layers, improving the degree of integration.
