摘要:
A thermal conductive sheet is obtained by preparing a resin layer; laminating a particle-containing monomer mixture layer which contains a monomer to be absorbed in the resin layer and a thermal conductive particle on one side surface of the resin layer; localizing the thermal conductive particle at one surface side by allowing the monomer to be absorbed in the resin layer; thereafter, reacting the monomer to be cured so as to fabricate a particle-localized sheet; laminating a plurality of the particle-localized sheets so as to allow one surface to be in contact with the other surface to fabricate a particle-localized sheet laminate; and then, cutting the particle-localized sheet laminate into a sheet shape along a laminating direction of each of the particle-localized sheets.

The present invention provides a temporary fixing sheet which firmly holds a ceramic sheet in a cutting step for the ceramic sheet and the like, can provide high cutting accuracy, and then can efficiently and easily peel a chip from itself by being cooled to a predetermined temperature or lower, with a high degree of freedom in designing and adequate handleability. The temporary fixing sheet includes a supporting substrate and a temporary fixing layer provided on at least one face thereof, wherein the temporary fixing layer contains a urethane polymer and a vinyl polymer.

The present invention provides a temporary fixing sheet which firmly holds a ceramic sheet in a cutting step for the ceramic sheet and the like, can provide high cutting accuracy, then can efficiently and easily peel a chip from itself by being cooled to a predetermined temperature or lower, gives a high degree of freedom to designing and has adequate handleability. The temporary fixing sheet has a resin layer which contains a urethane polymer component and a vinyl polymer, develops the tack strength at a particular temperature equal to or higher than 40° C., and loses the tack strength at the particular temperature or lower.

The present invention relates to a self-rolling pressure-sensitive adhesive sheet, comprising a shrinkable film layer which is contractible in at least one axial direction; a restriction layer restricting a contraction of the shrinkable film layer, the restriction layer being disposed on a side of the shrinkable film layer; and a pressure-sensitive adhesive layer disposed on the side of the restriction layer which is opposite to the side on which the shrinkable film layer is disposed, the self-rolling pressure-sensitive adhesive sheet being a releasable pressure-sensitive adhesive sheet, in which the pressure-sensitive adhesive layer or the pressure-sensitive adhesive layer after an adhesiveness decreasing treatment has a pressure-sensitive adhesive power (180° peeling, against a silicon mirror wafer, tensile speed: 300 mm/min) of 6.5 N/10 mm or less, and in which the self-rolling pressure-sensitive adhesive sheet rolls up in one direction from an end to form one tubular roll or rolls up from two opposing ends toward a center of the two opposing ends to form two tubular rolls, when the self-rolling pressure-sensitive sheet is stimulated to induce the contraction of the shrinkable film layer. The self-rolling pressure-sensitive adhesive sheet can be very easily peeled off from an adherend without causing a damage or a contamination on the adherend, even when it is adhered to an adherend of a relatively low strength.
