Abstract: Injection molding of a product and compressive decoration molding of a surface of the molded product are performed using individual cavity molds. A decorative film can be molded efficiently with a thermosetting coating material under suitable temperature control regardless of the shape of the molded product. An injection cavity mold and a decoration cavity mold are employed. The injection cavity mold is set at a hardening temperature of a thermoplastic resin. The decoration cavity mold is set at a thermosetting temperature of a coating material. A molded product is injection-molded in the cavity mold for injection molding and released from the mold. A decorative coating material composed of a liquid thermosetting composition is mounted at least on a part of the top of the injection-molded product. The molded product is located within the cavity mold for decoration molding.

An injection cavity mold and a decoration cavity mold are employed. The injection cavity mold is set at a hardening temperature of a thermoplastic resin. The decoration cavity mold is set at a thermosetting temperature of a coating material. A molded product is formed by injection molding in the injection cavity mold. The injection molded product is located within the decoration cavity mold to create a space as a cavity for decoration molding between an inner surface of the decoration cavity mold and a surface of the injection molded product.

Abstract: According to a method of manufacturing a magnetic head, a magnetoresistive device is formed on a substrate, a top end portion of the magnetoresistive device is placed in an external magnetic field, and a height of the magnetic head is adjusted by ceasing a polishing operation at an instant when change in resistance of the magnetoresistive device relative to change in the external magnetic field comes up to a predetermined value.

Abstract: A tape-on-wafer mounting apparatus and method for mounting a dicing tape on a wafer. The wafer stage mounts a wafer in the hole, which is constructed such that, when the wafer is mounted there, the wafer top surface stands higher than the wafer stage surface, with the wafer surface on which chip circuits are fabricated faced down. The tape stage mounts a dicing tape on its ring with the tape surface on which adhesives are applied faced down. The tape pressing tool presses the tape stage on the wafer stage so that the tape presser, which is constructed such that vertical force exerted by it is the largest at its center and smaller with the increase in distance from the center, causes the dicing tape to stick to the wafer.

Abstract: A wafer positioning apparatus includes at least first, second and third optical position detectors for detecting a circumference portion of a wafer. The first to third optical position detectors are arranged on a circumference of a circle having a diameter identical to that of the wafer. A transportation robot is used for holding the wafer and moving the held wafer with respect to the first to third optical position detectors. A control circuit controls the transportation robot in accordance with output signals of the first to third optical position detectors so that all of the first to third optical position detectors detect the circumference portion of the wafer at the same time.

Abstract: In an automatic wafer process for gate array integrated circuits, it becomes necessary to identify the wafer every time at the beginning of each process. However, it is difficult for conventional methods to identify the wafer by detecting a bar code pattern because of a low contrast due to reflection of the deposited layers. The present invention provides a method in which the light source, which abundantly includes infrared rays, located on the back side of the wafer and a detector located on the front side thereof. The infrared rays are irradiated onto the wafer easily penetrate the silicon wafer. The infrared rays are received without an effect of reflection due to the deposited layers on the front side of the wafer. The first metallization layer is a very suitable layer to form the bar code pattern, which is easily marked by a laser beam scriber.

Abstract: A method for transporting an article disposed on an upper surface of a stage in a vacuum. Gas is ejected through a plurality of inclined nozzles formed in the stage so that the article is transported in the direction of inclination of the nozzles.

Abstract: An automatic focus control device for adjusting the height of a lens above a surface of a workpiece used in an exposure apparatus for exposing the sample with a light beam including a first light emitting device for emitting a first light ray to a sample; a second light emitting device for emitting a second light ray to the sample. First and second light detecting devices for detect the second and first light rays reflected by a surface of the sample, respectively. The first and second light detecting device have a plurality of light detecting elements. A discriminating device discriminating between an inclination of the sample and a variation of the height of the lens above the surface of the sample on the basis of an output of the first and second light detecting devices.
