2. Description of the Related Art Conventionally, a semiconductor wafer is formed into chips by cutting the semiconductor wafer attached to the adhesive sheet to a part of the adhesive sheet with a cutter. Here, if the pressure-sensitive adhesive of the pressure-sensitive adhesive sheet is soft, there is a problem that the wafer itself is shaken during cutting, and a part of the chip is chipped. As a means for solving this problem, the present applicant employs an ultraviolet-curable pressure-sensitive adhesive to increase the cohesive force of the pressure-sensitive adhesive itself, thereby preventing the wafer itself from being shaken and chipping without chipping. (Japanese Patent Application No. 9-98342). Here, as an apparatus for attaching an adhesive sheet to the semiconductor wafer, there is a wafer mounter as disclosed in Japanese Patent No. 2517025, for example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, the cohesive force of an adhesive is increased by irradiating a semiconductor wafer fixing sheet with ultraviolet rays. Although it depends on the type of the ultraviolet curing initiator or the ultraviolet curable compound compounded in the pressure-sensitive adhesive, for example, the range is preferably 20 to 500 J / cm 2 (365 nm), more preferably 50 to 150 J / cm 2 (3
65 nm). This is because if the amount is too small, the cohesive force cannot be improved by irradiating the ultraviolet rays, and if the amount is too large, the speed of the ultraviolet irradiating line becomes slow and the productivity is deteriorated.

The ultraviolet irradiator can be appropriately selected as long as it has the above-mentioned ultraviolet irradiation amount, and specifically includes a low pressure mercury lamp, a high pressure discharge lamp, a short arc discharge lamp and the like. Examples of the low-pressure mercury lamp include a health line fluorescent lamp, a germicidal lamp, a fluorescent chemical lamp, and a black light. Examples of the high-pressure discharge lamp include a high-pressure mercury lamp and a metal halide lamp. There are a high pressure mercury lamp, a xenon lamp, a mercury xenon lamp and the like. As the ultraviolet irradiator, a low-pressure mercury lamp is preferable in consideration of the operating temperature of the lamp and the health of workers.
