Semiconductor device and method of fabricating the same, circuit board, and electronic instrument

A method of fabricating a semiconductor device, the method comprising:

• preparing a wiring board having an interconnecting pattern and mounting a first semiconductor chip on the wiring board, a surface of the first semiconductor chip having a first portion and second portion, and a first pad positioned on the first portion;
• electrically connecting the first pad to the interconnecting pattern by a wire;
• providing resin paste on the second portion of the surface of the first semiconductor chip so as not to deposit the resin paste on the first portion;
• mounting a second semiconductor chip having a second pad on the first semiconductor chip with the resin paste interposed between the first and the second semiconductor chips such that at least part of the first pad is covered by the second semiconductor chip with a space between the first and the second semiconductor chips;
• and
• forming a spacer by hardening the resin paste between the first and the second semiconductor chips to fix the first and the second semiconductor chips together,
• the spacer being formed to extend under the second pad and further outward, wherein the wire protrudes diagonally upward from a space above the first semiconductor chip.
