摘要： Provided are a die attach film, a semiconductor wafer, and a semiconductor packaging method. The die attach film can prevent generation of burrs or scattering of chips in a dicing process, and exhibits excellent expandability and pick-up characteristics in a die pressure-sensitive adhesive process. Further, the die attach film can prevent release, shifting, or deflection of a chip in a wire pressure-sensitive adhesive or molding process. Thus, it is possible to improve embeddability, inhibit warpage of a wafer or wiring substrate, and enhance productivity in a semiconductor packaging process.
