Patent ID: 7550673

Claim:
An electrode pattern for wire-bonding, comprising: a shorter sideline; a longer sideline; a wire-bonding reference pattern indicating a reference position for determination of a wire-bonding position; and a wire-bonding recognition pattern, wherein the following relationships are satisfied, L ≧14.3( W− 3 d/ 4), and Lb ≦14.3( W− 3 d/ 4), where L indicates a distance between (i) the reference position and (ii) a line that is parallel with the shorter sideline of the electrode pattern and passes through a position where a wire-bonding metal portion bonded to the electrode pattern has a maximum width in a direction parallel with the shorter sideline of the electrode pattern, Lb indicates a distance between (i) a line that passes through a center, in a direction parallel with the longer sideline of the electrode pattern, of the wire-bonding recognition pattern and is parallel with the shorter sideline of the electrode pattern and (ii) the line that is parallel with the shorter sideline of the electrode pattern and passes through the position where the wire-bonding metal portion has the maximum width in the direction parallel with the shorter sideline of the electrode pattern, d indicates a maximum width of the wire-bonding metal portion bonded to the electrode pattern in the direction parallel with the shorter sideline of the electrode pattern, and W indicates a width of the electrode pattern in the direction parallel with the shorter sideline of the electrode pattern.
