Abstract:
A semiconductor package includes a chip and a circuit substrate having leads. Each of the leads has an upper wide portion and a lower wide portion in a bonding area so as there are an upper notch and a lower notch in the bonding area. The upper and lower notches face toward the upper and lower wide portions of the adjacent lead, respectively. The upper and lower wide portions are designed to prevent defective bonding caused by shifting between the leads and the chip humps. Additionally, there are adequate etching spaces between the leads because the wide portions and the notches are staggered with each other such that incomplete etching between the leads is preventable during etching process.

Claim (Index 1):
A circuit substrate comprising:\n a carrier having a surface; a plurality of first leads formed on the surface, each of the first leads has a first upper wide portion, a first narrow portion, a first lower wide portion, an internal extending portion and a first lead section which are connected sequentially, wherein the first upper wide portion, the first narrow portion, the first lower wide portion and the internal extending portion are located in a first bonding area for bonding a chip; and a plurality of second leads formed on the surface, the first and second leads are aligned alternately along a transverse direction, each of the second leads has an external extending portion, a second upper wide portion, a second narrow portion, a second lower wide portion and a second lead section which are connected sequentially; wherein the external extending portion, the second upper wide portion, the second narrow portion and the second lower wide portion are located in a second bonding area for bonding the chip; wherein the first upper wide portion and the first lower wide portion are wider than the first narrow portion and the internal extending portion along the transverse direction such that a first upper notch facing toward the second upper wide portion and a first lower notch facing toward the second lower wide portion are formed in the first bonding area of each of the first leads; wherein the second upper wide portion and the second lower wide portion are wider than the external extending portion and the second narrow portion along the transverse direction such that a second upper notch facing toward the first upper wide portion and a second lower notch facing toward the first lower wide portion are formed in the second bonding area of each of the second leads.
