Semiconductor device and method of manufacturing the same

Abstract

To improve performance of a semiconductor device, a semiconductor device includes a wiring substrate, a semiconductor chip mounted on a first upper surface of the wiring substrate, an electronic component mounted on the first upper surface, and a stiffener ring fixed to the first upper surface. The stiffener ring includes a first portion arranged to continuously surround a periphery of the semiconductor chip in plan view and adhering to the first upper surface of the wiring substrate, and a second portion connected to the first portion and arranged at a position spaced away from the first upper surface of the wiring substrate in plan view. The second portion of the stiffener ring partially overlaps the electronic component.
