Abstract:
A method of manufacturing an electronic component comprising the steps of:providing a mother substrate; forming a plurality of elements of the electronic component on the mother substrate; forming an insulating/protecting film made of a photosensitive polyimide resin via a photolithographic process on an entire surface of the mother substrate except for polygonal-shaped areas surrounding each point where vertically and horizontally extending cut lines intersect each other such that portions of the mother substrate are exposed only at the polygonal-shaped areas surrounding each point where the cut lines intersect and such that the vertically and horizontally extending cut lines are covered by the cover material at all portions except portions located within the polygonal-shaped areas surrounding each point where the vertically extending cut lines intersect with the horizontally extending cut lines; and cutting out the plurality of the elements of the electronic component from the mother substrate by cutting the mother substrate along the intersecting cut lines; wherein the mother substrate is cut along the cut lines by using a dicing process and the dicing process begins at the exposed portions of the substrate where the horizontally extending cut lines intersect the vertically extending cut lines such that only the mother substrate is cut initially and then the cutting process continues such that the mother substrate and the cover material are cut together.
