    摘要: A laminated substrate and the semiconductor package utilizing the substrate are revealed. The laminated substrate primarily comprises a core layer, a first metal layer and a first solder mask disposed on the bottom surface of the core layer, and a second metal layer and a second solder mask disposed on the top surface of the core layer. The two solder masks have different CTEs to compensate potential substrate warpage caused by thermal stresses. Therefore, the manufacturing cost of the substrate can be reduced without adding extra stiffeners nor changing thicknesses of semiconductor packages to suppress substrate warpage during packaging processes. Especially, a die-attaching layer partially covers the second solder mask by printing and is planar after pre-curing for zero-gap die-attaching.

    摘要: A substrate panel primarily comprises a plurality of substrate strips arranged in an array, one or more current input lines, a plurality of cascaded lines connecting between the substrate strips, and a current input buffer gate. Current input lines connect a current input side of the substrate panel to the adjacent substrate strips. The current input buffer gate has a frame around the substrate strips and a plurality of meshes where the frame intersects with the current input lines and the meshes intersect with the cascaded lines with both ends of the meshes connecting to the frame. Therefore, the current can be evenly distributed to each substrate strip during plating processes to improve the issues of different plating thicknesses and different plating roughness caused by different current densities and to protect the internal circuits inside the substrate strips from the damages due to current surges and unstable voltages.

    摘要: A Chip-On-Lead (COL) multi-chip package is revealed, primarily comprising a plurality of leads, a first chip disposed on the first leads, one or more second chips stacked on the first chip, and an encapsulant. The leads have a plurality of internal leads encapsulated inside the encapsulant where the internal leads are fully formed on a downset plane toward and parallel to a bottom surface of the encapsulant. The height between the internal leads to a top surface of the encapsulant is three times or more greater than the height between the internal leads and the bottom surface. Since the number and the thickness of the second chips is under controlled, the thickness between the top surface of the encapsulant and the most adjacent one of the second chips is about the same as the one between the internal leads and the bottom surface of the encapsulant. Therefore, the internal leads of the leads without downset bends in the encapsulant can balance the upper and lower mold flows and carry more chips without shifting nor tilting.
