2. Description of the Related Art Conventionally, the step of die-bonding a semiconductor chip to a chip mounting substrate has been performed by applying a liquid adhesive at a predetermined position on the substrate and mounting the semiconductor chip thereon. As another method of die bonding, as a dicing sheet used when the semiconductor wafer is made into chips (individualization), a pressure-sensitive adhesive sheet having an adhesive layer for fixing the semiconductor wafer also functions as an adhesive for die bonding is used. Used,
Various methods have been proposed for peeling the adhesive layer from the base material of the tacky adhesive sheet with the adhesive layer left on the back surface of the chip at the time of pickup and thermocompressing the chip on the substrate via the adhesive layer (special feature.

However, when a liquid adhesive is applied to a substrate, it is difficult to control the adhesive in an appropriate amount, and a wide area chip, a very small chip, or a chip with a large aspect ratio is used. However, there was a risk that the adhesive would run short and the adhesive would stick out. When die-bonding is performed with a tacky adhesive sheet that also serves as the dicing process, the tacky adhesive sheet has a function of suppressing chip jump (chip fixing function), and the tacky adhesive layer peels from the base material of the tacky adhesive sheet. In many cases, the function to perform (peelability) and the function to adhere the chip and the substrate after die-bonding (die-bonding property) are in conflict with each other, which may make it difficult to select the optimum composition. It was

According to the method of manufacturing a semiconductor device of the present invention, a protective adhesive tape is attached to the circuit surface of a semiconductor wafer, and an adhesive film for die bonding is adhesively laminated on the back surface of the semiconductor wafer. Then, in a state where the semiconductor wafer is supported on the protective adhesive tape, dicing is performed from the side of the adhesive film, the semiconductor wafer is chipped together with the adhesive film, and the semiconductor chip is picked up from the protective adhesive sheet, It is characterized in that it is die-bonded to a chip mounting substrate by the adhesive film.

In the present invention, after a protective adhesive tape is attached to the circuit surface of the semiconductor wafer, the back surface of the semiconductor wafer is polished to a predetermined thickness, and then the bonding for die bonding is performed. The film may be adhesively laminated on the polished surface of the semiconductor wafer to perform the dicing step.

Further, it is preferable that the adhesive film is releasably laminated on a long process film, and is punched on the process film to have substantially the same size as a semiconductor wafer. According to the present invention as described above, since the die-bonding adhesive film is not required to have the chip fixing function or the peeling property, the material can be selected with an emphasis on the die-bonding property. Therefore, the material margin of the adhesive film is widened, which can contribute to cost reduction.

BEST MODE FOR CARRYING OUT THE INVENTION A method for manufacturing a semiconductor wafer according to the present invention will be specifically described below. In the present invention, first, as shown in FIG. 1, a protective adhesive tape 2 is attached to the circuit surface of a semiconductor wafer 1. The circuit is formed on the wafer surface by a general-purpose means such as an etching method or a lift-off method. In addition, after forming the circuit, the protective adhesive tape 2 may be attached to the circuit surface and the back surface of the wafer may be ground to adjust the thickness to a predetermined value. Here, the predetermined thickness is not particularly limited, but is generally about 50 to 500 μm.

As the protective adhesive tape 2, various adhesive tapes conventionally used for processing semiconductor wafers can be used. In the present invention, since it is necessary to peel the semiconductor chip from the pressure-sensitive adhesive layer 21 of the protective pressure-sensitive adhesive tape 2 after the completion of a predetermined process, the pressure-sensitive adhesive layer 21 is made of a so-called re-peeling type weak pressure-sensitive adhesive. Alternatively, it is preferably composed of an energy ray-curable pressure-sensitive adhesive capable of reducing the adhesive force by irradiation with energy rays.
