Abstract: A wafer temporary bonding method using silicon direct bonding (SDB) may include preparing a carrier wafer and a device wafer, adjusting roughness of a surface of the carrier wafer, and combining the carrier wafer and the device wafer using the SDB. Because the method uses SDB, instead of an adhesive layer, for a temporary bonding process, a module or process to generate and remove an adhesive is unnecessary. Also, a defect in a subsequent process, for example, a back-grinding process, due to irregularity of the adhesive may be prevented.

Abstract: Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated in an infinite loop back to the low absorption weld interface for reabsorption in the process. On each pass in the infinite loop, more infrared laser light is absorbed at the weld interface.
Abstract: A seal ring whose abutment joint portion is opened is fitted into an annular gap while the abutment joint portion is substantially closed. The annular gap is formed between an inner circumferential surface of a hole portion provided in an outer circumferential jig and an outer circumferential surface of an inner circumferential jig disposed in the hole portion, and has a heating region and a cooling region. The seal ring is passed through the heating region and then passed through the cooling region in the annular gap. The outer circumferential jig and the inner circumferential jig are maintained at a constant temperature higher than a glass transition temperature of a resin material for the seal ring in the heating region, and maintained at a constant temperature lower than the glass transition temperature of the resin material for the seal ring in the cooling region.
