Abstract

Disclosed are a chip protective film, a method for manufacturing the same, and a chip, which relate to the technical field of electronic chip protective films. The chip protective film includes: a first protective layer, and a second protective layer attached to at least a portion of a surface of the first protective layer. The second protective layer includes by mass: 90%-97% acrylate compounds; 0.1-5% fluorine-containing compounds; and a second adjuvant. The chip protective film features strong adhesion, low friction coefficient, high hardness, and good scratch resistance, which effectively solves the technical problem in the prior art that chip protective films are not scratch resistant.
