Patent ID: 11929342
Assignee: SHINKO ELECTRIC INDUSTRIES CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a lead frame including a lead that has a first end and a second end opposite to the first end;
a wiring substrate that is provided on the lead frame;
an electronic component that is provided between the lead frame and the wiring substrate;
a connection member that is provided between the lead frame and the wiring substrate and connects the lead frame and the wiring substrate; and
an encapsulating resin that is filled between the lead frame and the wiring substrate and covers the electronic component and the connection member, wherein
the lead includes:
a first surface opposed to the wiring substrate and covered by the encapsulating resin;
a second surface located on an opposite side of the lead than the first surface and exposed from the encapsulating resin;
an end surface of the second end covered by the encapsulating resin; and
an end surface of the first end exposed from a side surface of the encapsulating resin,

the second surface of the lead includes a step formed adjacent to the end surface of the first end and exposed from the encapsulating resin, and
a surface of the encapsulating resin from which the second surface of the lead is exposed includes another step formed adjacent to the step of the second surface of the lead.
