Beschreibung
Zusammenfassung:	An adhesive sheet for producing semiconductor devices, such as QFNs, can prevent the generation both of wire-bonding defects and mold flashes, and can thereby prevent the production of defective semiconductor devices. The present invention provides an adhesive sheet for producing semiconductor devices which is detachably attached to a lead frame and which comprises a heat resistant substrate and an adhesive layer which is arranged on one surface of the heat resistant substrate, wherein the adhesive layer contains, a thermosetting resin component (a) and a thermoplastic resin component (b); and the weight ratio of the component (a)/the component (b) is 0.3 to 3.
