Definitions
- the present invention relates to a photosensitive resin composition, a photosensitive element using the same, a resist pattern forming method, and a printed wiring board manufacturing method.
- the printed wiring board is manufactured as follows, for example. First, the photosensitive resin composition layer of the photosensitive element is laminated (laminated) on the circuit forming substrate (lamination step). Next, after peeling off and removing the support film, the exposed portion is cured by irradiating a predetermined portion of the photosensitive resin composition layer with actinic rays (exposure step). Thereafter, by removing (developing) the unexposed portion from the substrate, a resist pattern made of a cured product of the photosensitive resin composition is formed on the substrate (developing step). An etching process or a plating process is performed on the obtained resist pattern to form a circuit on the substrate (circuit forming process), and finally the resist is peeled and removed to produce a printed wiring board (peeling process).
- the resist shape is excellent. If the cross-sectional shape of the resist is trapezoidal or inverted trapezoidal, or if there is a tailing of the resist, there is a possibility that a short circuit or disconnection may occur in a circuit formed by the subsequent etching process or plating process. Therefore, it is desirable that the resist shape is rectangular and has no tailing.
