Since the gas generating agent is dissolved in the pressure-sensitive adhesive layer, the gas generated from the gas generating agent is efficiently released from the pressure-sensitive adhesive layer when irradiated with light. If the gas generating agent is present as particles in the pressure-sensitive adhesive layer, the locally generated gas may cause the pressure-sensitive adhesive layer to foam, and the gas may be released outside the pressure-sensitive adhesive layer. Furthermore, when light is irradiated as a stimulus for generating gas, light is scattered at the particle interface, resulting in low gas generation efficiency, or the surface smoothness of the pressure-sensitive adhesive layer may be deteriorated.

- Step 3 to be described later in order to set the gas release rate from the double-sided pressure-sensitive adhesive tape to 5 z LZcm 2 ′ min or more, the selection of the gas generating agent and the gas generating agent contained in the pressure-sensitive adhesive layer are performed.
- the content of is very important.
- the content of the gas generating agent may be appropriately selected depending on the type of the gas generating agent. For example, when an azo compound is used as the gas generating agent, 5 to 50 parts by weight with respect to 100 parts by weight of the adhesive. It is preferable that If it is less than 5 parts by weight, a sufficient gas release rate cannot be obtained and self-peeling may not be realized. If it exceeds 50 parts by weight, the solubility may deteriorate and problems such as bleeding may occur. More preferably, it is 15-30 parts by weight.
- the pressure-sensitive adhesive constituting the surface containing the gas generating agent is preferably a stimulus-curing pressure-sensitive adhesive whose adhesive strength is reduced by stimulation.

- the amount of light irradiation at this time also greatly affects the gas release rate from the double-sided pressure-sensitive adhesive tape.
- the amount of light applied to the double-sided pressure-sensitive adhesive tape can be appropriately determined according to the type and content of the gas generating agent, the thickness of the support, etc., but 20-1 000 mW / cm 2 It is preferable to irradiate the light having the intensity of 2000 to 6000 mj / cm 2 .
- the light intensity is less than 20 mWZcm 2 , sufficient gas release rate may not be obtained and self-peeling may not be achieved. If it exceeds 1000 mW / cm 2 , the pressure from the generated gas becomes too high, and the IC chip May be damaged.
- the integrated light intensity is less than 2000 mj / cm 2 , sufficient gas release amount may not be obtained and self-peeling may not be achieved. If it exceeds 6000 mjZcm 2 , the IC chip may be damaged.
- irradiation is performed with light having an intensity of 30 to 200 mW / cm 2 so as to have an energy of accumulated light intensity 000 5000 mjZ cm 2 .
- the gel fraction of the adhesive layer on the surface in contact with the wafer at the time of irradiating 1/3 of the total irradiation amount in step 3 is 90% or more. Is preferred. If it is less than 90%, the adhesive layer is not sufficiently hard at the start of gas generation, and the generated gas momentum is absorbed by the soft adhesive layer, or the adhesive layer foams and self-peeling. May be difficult to occur.
- the total irradiation amount means the integrated light amount irradiated until the wafer is lifted by self-peeling.
- the elastic modulus of the adhesive layer on the surface in contact with the wafer at the time of irradiating 1/3 of the total irradiation amount in step 3 is 5 ⁇ 10 4 Pa or more. I prefer to be there. If the pressure is less than 5 X 10 4 Pa, the strength of the generated adhesive layer is not sufficiently hard at the start of gas generation, and the generated gas momentum is absorbed by the soft adhesive layer, and self-peeling may not occur easily.
- the gas release rate from the double-sided pressure-sensitive adhesive tape in step 3 is 5 ⁇ L / cm 2 ′ or more. If it is less than 5 x LZcm 2 'minutes, the adhesive layer of the double-sided adhesive tape will not completely peel from the wafer, and the adhesive part will remain in an island shape, making it impossible to achieve self-peeling.
- Such gas release rate is adjusted by adjusting various conditions such as the type and content of the gas generating agent, the gel fraction and elastic modulus of the pressure-sensitive adhesive layer at the time of peeling, and the amount of UV irradiation at the time of peeling as described above. Obtainable. [0050] In this specification, as shown in Fig.
- the gas release rate is determined by producing a sealed chamber with the irradiation surface sealed with glass, and connecting the outlet of the chamber with a pipette using a rubber tube. Also, connect the other outlet of the measuring pipette to the funnel with a rubber tube, add an appropriate amount of water, raise the measuring pipette vertically, open the three-way valve, and adjust the position of the funnel.
- the IC chip manufacturing method of the present invention includes the step 4 of peeling the double-sided adhesive tape from the wafer. Since the double-sided adhesive tape and the wafer are self-peeled by irradiating light in step 3, even an extremely thin IC chip with a thickness of 50 ⁇ m or less, for example about 25-30 ⁇ m, It can be easily peeled off without being damaged.
