A performance of a semiconductor device is improved. A method of manufacturing a semiconductor device according to one embodiment includes a step of mounting a cover member via a bonding material on an upper surface of a frame member fixed on a wiring substrate, and a step of curing the bonding material by irradiating the bonding material mounted on the frame member with an ultraviolet ray. The wiring substrate has a base member and an insulating film covering the base member, and the frame member and a semiconductor chip are mounted (fixed) onto an upper surface of the insulating film. The frame member contains glass fibers. Moreover, a roughness of the upper surface of the frame member is equal to or less than a roughness of the upper surface of the insulating film.

Method of manufacturing semiconductor device and semiconductor device

A semiconductor device includes a semiconductor chip having a first main surface, a second main surface opposite to the first main surface, a side surface arranged between the first main surface and the second main surface, and a magnetic storage device, a first magnetic shield overlaying on the first main surface, a second magnetic shield overlaying on the second main surface, and a third magnetic shield overlaying on the side surface. The first and second magnetic shields are mechanically connected via the third magnetic shield.

Semiconductor device including a plurality of magnetic shields

A semiconductor chip includes a magnetic storage device and includes an electrode pad on a first face. The semiconductor chip is coated with a magnetic shield layer in a state in which at least the electrode pad is exposed. The semiconductor chip is mounted on an interconnect substrate through a bump. At least one of the semiconductor chip and the interconnect substrate includes a convex portion, and the bump is disposed over the convex portion.
