Assignee: AMKOR TECHNOLOGY JAPAN, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A semiconductor package comprising:
a lead frame comprising external connection terminals;
a semiconductor device coupled to the external connection terminals with interconnects;
a sealing member covering portions of the external connection terminals and the semiconductor device; and
a plating structure;
wherein:
the external connection terminals comprise:
bottom ends exposed from the sealing member;
outer terminal portions having side ends exposed from the sealing member; and
inner terminal portions opposite to and coupled to the outer terminal portions;

the plating structure fully covers at least a top portion of the side ends;
the external connection terminals are on at least two adjoining sides of the semiconductor device;
the plating structure consists of a structure that is external to the sealing member so that the portions of the external connection terminals covered by the sealing member are devoid of the plating structure;
the inner terminal portions comprise side ends;
portions of the side ends of the inner terminal portions are exposed from the sealing member; and
the portions of the side ends of the inner terminal portions that are exposed are devoid of the plating structure.
