Assignee: KIOXIA CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A method of manufacturing a semiconductor device, the method comprising:
stacking a plurality of first semiconductor chips on a first wiring substrate having: (i) a first surface, the first surface provided with a plurality of first electrode pads, and (ii) a second surface opposite to the first surface;
forming a first columnar electrode by:
bonding a wire to one of the plurality of first electrode pads,
pulling out the wire in an oblique direction with respect to a first direction substantially perpendicular to the first surface, and
cutting the wire;

covering the plurality of first semiconductor chips and the first columnar electrode with a first resin layer;
polishing the first resin layer to expose the first columnar electrode; and
stacking a second wiring substrate on the first resin layer, and electrically connecting the first columnar electrode to a second electrode pad provided on the second wiring substrate.
