Abstract
A method of manufacturing a plurality of identical electronic component modules includes: preparing an assembly substrate that includes a plurality of electronic components mounted thereon; digging a first groove along the dicing lines from a top surface of a sealing member that seals each electronic component, the first groove penetrating the sealing member and reaching an intermediate depth within a base substrate; widening an upper portion of the first grove to define a second groove that is continuous with the lower portion of the first groove; forming a shielding film by depositing a film made of a conductive material on the top surface of the sealing member and on inner walls of the first and second grooves that include the sidewalls of the sealing member; and thereafter, cutting the base substrate at a bottom of the lower portion of the first groove along dicing lines.
