Abstract

An element chip manufacturing method includes a preparation process of preparing a substrate which includes a first surface having an exposed bump and a second surface opposite to the first surface and includes a plurality of element regions defined by dividing regions, a bump embedding process of embedding at least a head top part of the bump into the adhesive layer, a mask forming process of forming a mask in the second surface. The method for manufacturing the element chip includes a holding process of arranging the first surface to oppose a holding tape supported on a frame and holding the substrate on the holding tape, a placement process of placing the substrate on a stage provided inside of a plasma processing apparatus through the holding tape, after the mask forming process and the holding process.
