摘要

PROBLEM TO BE SOLVED: To provide: a protective film forming film and a protective film forming sheet, which are attached on a rear face of a workpiece such as a semiconductor wafer, which can form a protective film on a rear face of a processed product such as a semiconductor chip, which are suitable for dividing and processing a workpiece by a modified layer destructing tensile divide during a process for obtaining a processed product after being attached on a rear face of a workpiece, and which are also suitable for performing an infrared inspection of a processed product while a protective film is attached on a rear face thereof; a method for manufacturing a workpiece or a processed product using the protective film forming film or the protective film forming sheet; an inspection method using the protective film forming film or the protective film forming sheet; and a workpiece and a processed product which are determined as an adequate product by means of the inspection method.SOLUTION: A protective film forming film contains an organic coloring agent, has a content of carbon black of 0.05 mass% or less, and has a light transmittance at a wavelength of 1,064 nm of 60% or more and a light transmittance at a wavelength of 1,250 nm of 65% or more.SELECTED DRAWING: Figure 2
