Method of manufacturing electronic component

Abstract

The yield of a product is improved when a substrate held by a conveyance carrier is subjected to a plasma treatment. A method of manufacturing an electronic component includes preparing a substrate which is bonded to a holding sheet of a conveyance carrier, the conveyance carrier including the holding sheet and a frame disposed on an outer peripheral portion of the holding sheet, the substrate having a circuit layer; heating the holding sheet after preparing the substrate; cooling the holding sheet after heating the holding sheet; and plasma etching the substrate to singulate the substrate into the electronic component in a state that the substrate is placed above a stage included in a plasma treatment apparatus and the substrate is in contact with the stage via the holding sheet.
