Document Type and Number:
Japanese Patent JP7256851
Kind Code:
B2
Abstract:
To provide a kit including a curable resin film that can improve the strength of a semiconductor chip, can prevent peeling of a protective film, and is excellent in reworkability when attached to the rear face of a semiconductor wafer.SOLUTION: A kit includes: a first curable resin film (x1) for forming a first cured resin film (r1) as a protective film on both a bump formation surface including bumps and side faces of a semiconductor chip having the bump formation surface; and a second curable resin film (x2) for forming a second cured resin film (r2) as a protective film on a surface on the opposite side of the bump formation surface of the semiconductor chip. The peel force of the second curable resin film (x2) with respect to a silicon wafer (mirror plane) is 3,000 mN/25 mm or less.SELECTED DRAWING: Figure 1
