Summary:The present invention relates to a method for encapsulating a substrate, which comprises: (a1) providing a substrate with a plurality of chips mounted on a top side of the substrate; (b1) compressing a dry film photoresist on the top side of the substrate to form a photoresist layer; (c1) exposing the photoresist layer to a light source through a mask to form unexposed photoresist regions and exposed photoresist regions; (d1) developing the photoresist layer to uncover underlying portions of the unexposed photoresist regions; (e1) molding the top side of the substrate with a molding material; (f1) curing the molding material; and (g1) removing the exposed photoresist regions from the substrate with a photoresist-removing agent.
