Abstract
A bare chip carrier for holding a bare chip includes a bare chip carrier base member, a bump electrode which is located above a principal surface of the bare chip carrier base member and which is to be connected to a pad electrode of the bare chip, a bare chip carrier electrode which is formed on a back surface of the bare chip carrier base member and which has a recessed portion, and a wiring that connects the bump electrode to the bare chip carrier electrode.
Claims6
A bare chip carrier for holding a bare chip, comprising:
- a base member;
- a first electrode which is located above a principal surface of said base member, and which is to be connected to said bare chip;
- a second electrode which is formed on a back surface of said base member, and which has a recessed portion formed in the surface of the second electrode but not penetrating to the base member, the recessed portion having a rough surface;
- and
- a wiring that connects said first electrode to said second electrode.
