摘要:
The present invention relates to a semiconductor device with a plurality of mark through substrate vias, including a semiconductor substrate, a plurality of original through substrate vias and a plurality of mark through substrate vias. The original through substrate vias and the mark through substrate vias are disposed in the semiconductor substrate and protrude from the backside surface of the semiconductor substrate. The mark through substrate vias are added at a specific position and/or in a specific pattern and serve as a fiducial mark, which facilitates identifying the position and direction on the backside surface. Thus, the redistribution layer (RBL) or the special equipment for achieving the backside alignment (BSA) is not necessary.

A package structure and a package process are proposed in using pillar bumps to connect an upper second chip and through silicon vias of a lower first chip, wherein a gap between the first chip and the second chip can be controlled by adjusting a height of the pillar bumps. In other words, the pillar bumps compensate the height difference between the first chip and a molding compound surrounding the first chip so as to ensure the bondibility between the pillar bumps and the corresponding through silicon vias and improve the process yield. Furthermore, the pillar bumps maintain the gap between the second chip and the molding compound for allowing an underfill being properly filled into the space between the first chip and the second chip.

A circuit substrate suitable for being connected to at least one solder ball is provided. The circuit substrate includes a substrate, at least one bonding pad, and a solder mask. The substrate has a surface. The bonding pad is disposed on the surface of the substrate for being connected to the solder ball. The solder mask covers the surface of the substrate and has an opening for exposing a portion of the bonding pad. The opening has a first end and a second end. As compared with the second end, the first end is much farther from the bonding pad, and a diameter of the first end is larger than that of the second end.

The present invention relates to a method for making chip assemblies, including the following steps of: (a) providing a tested upper wafer and at least one tested lower wafer; (b) sawing the at least one tested lower wafer to form a plurality of lower dice, the lower dice including a plurality of know good lower dice; (c) picking up and rearranging the know good lower dice on a carrier according to the wafer map of the upper wafer; (d) bonding the upper wafer and the carrier; (e) removing the carrier; and (f) proceeding sawing step. Whereby, the dice of the die assembly are both known good dice, thus the yield loss caused by the different yields between the upper wafer and the lower wafer will not occur.

A package process is provided. First, a semiconductor substrate is disposed on a carrier, in which a surface of the carrier has an adhesive layer and the semiconductor substrate is bonded to the carrier by the adhesive layer. Next, a chip is bonded on the semiconductor substrate by flip chip technique and a first underfill is formed between the chip and the semiconductor substrate to encapsulate a plurality of first conductive bumps at the bottom of the chip. Then, a first molding compound is formed on the semiconductor substrate. The first molding compound at least encapsulates the side surface of the chip and the first underfill. Finally, the semiconductor substrate together with the chip and the first molding compound located thereon are separated from the adhesive layer of the carrier to form an array package structure.
