A semiconductor device includes a semiconductor chip having a passivation film, a stress relieving layer provided on the passivation film, and a groove formed in a periphery of a surface of the semiconductor chip, the groove being provided inside of an edge of the semiconductor chip, wherein the stress relieving layer is partly disposed in the groove.

Semiconductor device and method for manufacturing semiconductor device

A semiconductor device includes a wiring board, a semiconductor chip, and a connecting member provided between a surface of the wiring board and a functional surface of the semiconductor chip. The connecting member extends a distance between the wiring board surface and the functional surface. A sealing material seals a gap space between the wiring board and the semiconductor chip. An electrode is formed at the wiring board surface and arranged outside of an outer periphery of the sealing material. A lateral distance between an outer periphery of the semiconductor chip and the outer periphery of the sealing material is between 0.1 mm and a lateral distance from the outer periphery of the semiconductor chip to the electrode.

Semiconductor device with a semiconductor chip connected in a flip chip manner

A semiconductor device () includes a solid state device (), a semiconductor chip () that has a functional surface () on which a functional element () is formed and that is bonded on a surface of the solid state device with the functional surface thereof facing the surface of the solid state device and while maintaining a predetermined distance between the functional surface thereof and the surface of the solid state device, an insulating film () that is provided on the surface () of the solid state device facing the semiconductor chip and that has an opening () greater in size than the semiconductor chip when the surface of the solid state device facing the semiconductor chip is vertically viewed down in plane, and a sealing layer () that seals a space between the solid state device and the semiconductor chip.

An inventive semiconductor device includes a semiconductor chip having a passivation film, and a sealing resin layer provided over the passivation film for sealing a front side of the semiconductor chip, a groove formed in a periphery of a surface of the semiconductor chip being tapered toward a rear surface of the semiconductor chip, wherein the sealing resin layer is partly disposed in the groove.

An inventive semiconductor device includes a semiconductor chip having a passivation film, and a sealing resin layer provided over the passivation film for sealing a front side of the semiconductor chip. The sealing resin layer extends to a side surface of the passivation film to cover the side surface.
