Abstract:
A method of fabricating an electronic circuit device comprising:mounting an electronic part in a cavity formed in a package main body by using a bonding material comprising at least one of a die bonding material and a conductive paste for wiring;bonding the package main body and a cap by performing a heat treatment while a sealing material is interposed between a peripheral edge portion of the cavity in the package main body and the cap whereby the cavity is sealed in an airtight manner; andbaking the package main body and the mounted electronic part to a baking temperature set higher than a heating temperature of the heat treatment for a predetermined time period prior to the bonding step, wherein said baking of said package main body generates gases by thermally decomposing said bonding material, said gases being discharged outside of said package main body.
