摘要： The present invention relates to a semiconductor package. The semiconductor package includes a substrate, at least one chip, a plurality of conductive elements, a plurality of first conductors and a molding compound. The substrate has a plurality of first pads and a solder mask. The first pads are exposed to a first surface of the substrate, and the material of the first pads is copper. The solder mask is disposed on the first surface, contacts the first pads directly, and has at least on opening so as to expose part of the first pads. The chip is mounted on the first surface of the substrate. The conductive elements electrically connect the chip and the substrate. The first conductors are disposed on the first pads. The molding compound is disposed on the first surface of the substrate, and encapsulates the chip, the conductive elements and part of the first conductors. Whereby, the solder mask contacts the first pads directly, and thus results in higher bonding strength, so as to avoid the bridge between the first conductors caused by the first conductors permeating into the interface between the solder mask and the first pads.

摘要： The present invention relates to a semiconductor package. The semiconductor package includes a substrate, at least one chip, a plurality of conductive elements, a plurality of first conductors and a molding compound. The substrate has a plurality of first pads and a solder mask. The first pads are exposed to a first surface of the substrate, and the material of the first pads is copper. The solder mask is disposed on the first surface, contacts the first pads directly, and has at least one opening so as to expose part of the first pads. The chip is mounted on the first surface of the substrate. The conductive elements electrically connect the chip and the substrate. The first conductors are disposed on the first pads. The molding compound is disposed on the first surface of the substrate, and encapsulates the chip, the conductive elements and part of the first conductors. Whereby, the solder mask contacts the first pads directly, and thus results in higher bonding strength, so as to avoid the bridge between the first conductors caused by the first conductors permeating into the interface between the solder mask and the first pads.

摘要： A substrate structure having a solder mask and a process for making the same, including (a) providing a substrate having a top surface, the top surface having a die pad and a plurality of solder pads; (b) forming a first solder mask on the top surface, the first solder mask having a plurality of openings, each opening corresponding to each solder pad so as to expose at least part of the solder pad; and (c) forming a second solder mask on the first solder mask. The substrate structure can be used for packaging a thicker die so as to prevent the die crack and the overflow of molding compound will be avoided.
