摘要： A mold array process (MAP) for manufacturing a plurality of semiconductor packages is revealed. Firstly, a substrate strip including a plurality of substrate units arranged in an array within a molding area is provided. A plurality of chips are disposed on the substrate units. An encapsulant by molding is formed on the molding area of the substrate strip to continuously encapsulate the chips. During the molding process, an adjustable top mold is implemented where a cavity width between two opposing sidewalls inside a top mold chest can be adjusted to make the mold flow speeds at the center and at the side rails of the molding area the same.

Each semiconductor package comprises a substrate and a chip disposed on the substrate. The micro contacts of the bottom semiconductor package are a plurality of top bumps located on the upper surface of the substrate. The micro contacts of the top semiconductor package are a plurality of bottom bumps located on the lower surface of the substrate. The bottom bumps are aligned with the top bumps and are electrically connected each other by the solder paste.

摘要： A chip packaging process integrates a burn-in test or a high temperature test to simplify overall packaging and testing process flow. One or more chips are disposed on one or more units of a substrate strip where the substrate strip has a plurality of electrical open sections at the plating lines to electrically isolate the external pads between different units. After electrical connection and encapsulation, a burn-in test is executed at the same time of a post mold curing step, with a high-temperature testing if necessary. Therefore, the chips on the substrate strip has been gone through the burn-in test during the encapsulant is completely cured at the post mold curing step and the burn-in test is finished before the singulation step to reduce the overall testing time.

摘要： An IC package with a near-substrate-scale die-attaching layer includes a substrate, a near-substrate-scale die-attaching layer, a chip, a plurality of bonding wires, an encapsulant, and a plurality of solder balls. A plurality of ball pads are formed on the bottom surface of the substrate for solder ball placement. The near-substrate-scale die-attaching layer is formed on the top surface of the substrate covering most of the top surface above the ball pads without extending to the edges of the top surface. The active surface of the chip is attached to a first portion of the near-substrate-scale die-attaching layer and is electrically connected to the substrate by the bonding wires. The encapsulant is formed above the top surface of the substrate to cover a second portion of the near-substrate-scale die-attaching layer extending between the substrate and the encapsulant. Therefore, without adding extra components, the intense thermal stresses imposed on some specific solder balls at the corners of the bottom surface of the substrate or under the edges of the chip will be reduced. During on-board TCT, the solder balls will not easily be broken so that the reliability of IC package is enhanced. Moreover, the near-substrate-scale die-attaching layer is completely encapsulated by the encapsulant 250 to have a better resistance to moisture.

摘要： The surface of the circuit substrate is a solder mask. The solder mask protects the electrical circuit on the circuit substrate against suffering from the environmental damage. By dividing the area of the circuit substrate into the solder mask area and the adhesive area, a bismaleimide triazine layer is formed on the surface of the circuit substrate to coarsen the adhesive area and so as to enhance the adhesion strength between the chip and the circuit substrate.
