Manufacturing method of electronic device

Abstract

A manufacturing method of an electronic device includes, in the following order: a process of preparing a structure P provided, in this order, with an electronic component, a surface protective film that becomes water-rinsable after at least one treatment selected from light irradiation and heating, and a backgrinding tape; a BG process of backgrinding, in the structure P, a surface of the electronic component that is opposite to a surface on the surface protective film side; a processing process of performing, with respect to the surface protective film, at least one treatment selected from light irradiation and heating; and a protective film removal process of removing the surface protective film.
