Patent ID: 7125744

Claim:
A method for manufacturing a high-frequency module, comprising: a substrate; a high-frequency circuit that is mounted on a surface of the substrate and comprises a high-frequency semiconductor element; an insulating resin formed so as to seal at least the high-frequency semiconductor element; and a metal thin film formed on a surface of the insulating resin, wherein the high-frequency circuit further comprises a wiring pattern; the wiring pattern is electrically connected to the metal thin film; the surface of the substrate comprises a first region in which the insalating resin is formed and a second region in which no insulating resin is formed; and the wiring pattern exposed at the surface of the substrate in the second region is electrically connected to the metal thin film, the method comprising forming the insulating resin by molding and exposing a part of the wiring pattern at the surface of the substrate by irradiation with a laser beam or mechanical grinding performed after the molding of the insulating resin, wherein the irradiation with the laser beam or the mechanical grinding is performed after positioning with a mark that has been preformed on a face opposite to the surface of the substrate on which the high-frequency circuit is disposed.
