When the adhesive sheet is peeled off, the bonding is sometimes performed on the connection terminal of the semiconductor package or the mold resin surface. Agent movement (hereinafter referred to as "residual paste") phenomenon. When such a paste phenomenon occurs, 'because the adhesive is adhered to the mold-attached material on the outside of the lead resin, and the material is semiconducting, the device is mounted on the wiring board, etc. A connection failure condition will occur. SUMMARY OF THE INVENTION A local innovation has been innovated to solve the above problems, and an object thereof is to provide a good bow-and-wire bonding property and a mold overflow-free property when used for manufacturing a semiconductor such as QFN.

It is preferable to provide a protective film on one side of the adhesive layer. The bonding strength at the time of bonding to copper or gold-plated copper is preferably 0.098 N/cm or more. The semiconductor device of the present invention is manufactured by using the above-mentioned adhesive sheet for semiconductor device manufacturing. The method of manufacturing a semiconductor device of the present invention is carried out by using the above-mentioned adhesive sheet for manufacturing a semiconductor device. [Embodiment] The present invention will be described in detail below. The adhesive sheet of the present invention comprises a thermoplastic resin component (8), or a thermosetting resin component (4), and an adhesive layer of the re-peelability-imparting component (c) on one side of the heat-resistant substrate. And constitute. The heat resistant substrate may, for example, be a heat resistant resin film or a metal case. When the adhesive layer of the present invention is used to manufacture a semiconductor device such as qfn, the bonding sheet is exposed to a high temperature of 15 〇i25 (rc) in the wafer bonding step, the wire bonding step, and the resin packaging step. When the base material is a heat-resistant resin film, since the thermal expansion coefficient of the heat-resistant resin 将 increases I 遽 to a glass transition temperature, the thermal expansion difference between the above 1 and the metal wire is increased, and thus heat resistance is returned when returning to room temperature. The resin film 盥 lead frame is likely to be buckling. Because the heat-resistant resin film and the wire 竿 _ 'in the resin packaging step' can not be placed on the positioning pins of the nuclear device, fear 315674 8 1313481 Therefore, when the heat-resistant substrate is made of a heat-resistant resin film, it is preferable to use a heat-resistant resin film having a breaking temperature of 1 50 C or more, especially 8: In addition, the thermal expansion coefficient of the heat resistant resin film in the range of 150 to 250 t is preferably 5 to 50 ppm/t: especially 1 because the difference in thermal expansion between the lead frame and the metal lead frame is as small as possible. 〇 to 3〇ppm /t: It is preferable. The heat resistant resin film having the relevant characteristics can be exemplified by, for example, polyimine, polyamine, polyether maple, "phenylene sulfide, polyether ketone, ether ether ketone, triethyl ethane A film composed of cerium cellulose, polyether sulfimine, etc. — When the heat-resistant substrate is made of metal _, the metal is in the 15 () to 25 generations because of the reason of the heat-resistant resin film. The coefficient of thermal expansion is preferably 5 to 50 ppmrc, especially 1 to 3 ppm rc. It can be exemplified by metals such as gold, silver, copper, platinum, samarium, magnesium, titanium, chromium, manganese. a metal box composed of iron, nickel, zinc, handle, lock, marriage, tin, & or an alloy box containing the metals as the main component; or such a mineral metal knot. When the bonding device is used to manufacture a semiconductor device, in order to prevent the occurrence of residual paste in the peeling step of the adhesive sheet, the bonding strength Sa between the heat-resistant substrate and the adhesive layer, and between the sealing resin and the lead frame and the adhesive layer are The ratio of the strength Sb (bonding strength ratio) Sa/Sb is preferably at least $. ^ In the case of low squares, 1 · 5, because it is sticky In the peeling step of the film, it is better to avoid the situation of the residue. In addition, in order to set the bonding strength ratio Sa/Sb ° to 1.5 or more, when it is in the heat-sensitive resin film, it is better to stick to t. Before the adhesive layer, the side surface of the adhesive layer formed by the heat-sensitive resin film is subjected to corona treatment, t-pulp treatment, primer coating treatment, spray 315674 9 1313481 sand, etc., to improve the heat-resistant resin film and adhesion. The treatment of the bonding strength sa between the bonding layers. In addition, in the case of the metal case, the rolling metal drop and the electrolytic metal can be distinguished from the manufacturing process, but the bonding strength ratio Sa/sb is set at i 5 or more, It is preferable to use an electrolytic metal sap while adjusting the layer on the surface of the roughened side. Moreover, 'electrolytic metal flute+ is also preferred to use electrolytic copper foil. Furthermore, the lead frame composed of the adhesive layer and copper (or gold-plated copper), f temperature is 15 〇 to 20 (rc, the bonding strength of the adhesive layer and the lead frame is preferably 0.098 N / More than cm, this is when the 〇〇98Ν- or more, it can be said that the mold overflow performance can be sufficiently prevented. The adhesive layer is made of thermoplastic resin component (8) and re-peelability imparting component (4). It is preferable to further contain a thermosetting tree component (4). In these two cases, the reset ratio (4)/(b) of the thermosetting resin component (4) and the thermoplastic resin component (9) is preferably 3.5 or less, in particular, a)/(b) is preferably from 0.3 to 3.5, and preferably from 33 to 2.5, and more preferably 1 S 2.5. Field U)/(b) is greater than 3.5 because of stickiness The adhesive layer has a reduced flexibility, so that the adhesive sheet lead frame is subjected to the electro-poly cleaning step, and the adhesive force of the adhesive sheet is reduced in the resin packaging step, which causes the lead frame and the adhesive sheet to be partially peeled off, and the mold overflow occurs. It is also more prone to remnant conditions. On the other hand, if (a)/(b) 2 is at 0.3, the elastic modulus is lowered, and the wire bonding failure is liable to occur, so that it is preferably avoided. a mixture of the thermosetting resin component (a) of the drill layer component and the thermoplastic tree component (b) or only the thermoplastic resin component (b) and the re-peelability component (c) The weight ratio ((a) + (b)) / (c) (or 315674 10 1313481 (b)) / (c)) ' is preferably from 6 to 2,000. Especially ((a) + (b)) / (c) or (b) / (c) is preferably from 10 to 1,000. When (U) + (b)) / (c) or (b) / (c) is lower than 6, since the adhesion between the lead frame and the bonding sheet is lowered, the lead frame is caused in the resin packaging step. The adhesive sheet is partially peeled off to cause mold overflow, and is also prone to residual paste. On the other hand, if it is greater than 2, if the electrode holder is used in the plasma cleaning step, the adhesion between the lead frame and the bonding sheet is increased, so the bonding sheet for semiconductor manufacturing is used again. When peeling off, it will be prone to remnants. When an appropriate amount of the thermosetting resin component is contained in the adhesive layer component, the wire bonding property can be improved and the die overflow property can be improved. The thermosetting resin component (a) can be exemplified by, for example, a urea resin, a melamine resin, a benzoguanamine resin, a mercaptophthalamide resin, a phenol resin, a resorcin resin, a xylene resin, a furan resin, or an unsaturated polyester resin. , diallyl phthalate resin, isocyanate resin, epoxy resin, maleimide resin, nadimide resin, and the like. In addition, the resins may be used singly or in combination of two or more kinds. In particular, by using at least one of epoxy resin phenylene resins, it is possible to obtain at the processing temperature of the wire bonding step. The secret rate 'and at the processing temperature of the resin encapsulation step, can present a higher adhesion strength between the lead frame and the adhesive layer. The thermoplastic resin component (b) may, for example, be a propylene dibutyl phthalate (NBR) or (iv) a nitrile: a resin (abs), a benzene-butadiene-stact ethylene resin (SEBS), or a styrene.碑乙坤 (SBS), polybutadiene, polyacrylonitrile '$vinyl resin ♦ vinyl butyral, polyamine, 315674 11 1313481 polyaminimide, polyimine, m, polyamine Among them, polydimethyl oxa aurethane and the like, particularly, a polyamide-bonded polyamine, a polyamidoximine, and a polyacrylonitrile-butadiene copolymer resin have superior heat resistance, and thus are preferred. Further, the thermoplastic resin component (b) has a weight average molecular weight of 2' 〇〇〇 to 1' 〇〇〇, and 〇〇〇' is preferably 5 Å to 纲, especially I. , . . . 500,000 is better. If the viscosity of the adhesive layer is increased within this range, the sticking phenomenon in the peeling step of the adhesive sheet can be further prevented.
