CHIP PACKAGE AND FABRICATION METHOD THEREOF
First Claim
1. A chip package, comprising:
- a carrier substrate having an upper surface and an opposite lower surface and having a first side surface and a second side surface;
a chip disposed on the upper surface or the lower surface of the carrier substrate and having a first electrode and a second electrode;
a first trench extending from the upper surface toward the lower surface of the carrier substrate and extending from the first side surface toward an inner portion of the carrier substrate;
a first conducting layer located on a sidewall of the first trench and electrically connected to the first electrode, wherein the first conducting layer is not coplanar with the first side surface and is separated from the first side surface by a first minimum distance;
a second trench extending from the upper surface toward the lower surface of the carrier substrate and extending from the second side surface toward the inner portion of the carrier substrate; and
a second conducting layer located on a sidewall of the second trench and electrically connected to the second electrode, wherein the second conducting layer is not coplanar with the second side surface and is separated from the second side surface by a second minimum distance.

Abstract
A chip package includes a substrate having an upper, a lower, a first side, and a second side surfaces, a chip having a first and a second electrodes, a first trench extending from the upper surface toward the lower surface and from the first side surface toward an inner portion of the substrate, a first conducting layer overlying a sidewall of the first trench and electrically connecting the first electrode, which is not coplanar with the first side surface and separated from the first side surface by a first distance, a second trench extending from the upper surface toward the lower surface and from the second side surface toward the inner portion, and a second conducting layer overlying a sidewall of the second trench and electrically connecting the second electrode, which is not coplanar with the second side surface and separated from the second side surface by a second distance.

12. A method for forming a chip package, comprising:
-
providing a carrier wafer comprising a plurality of regions defined by a plurality of predetermined scribe lines; forming a plurality of through-holes penetrating through an upper surface and an opposite lower surface of the carrier wafer on locations of the predetermined scribe lines; forming a conducting material layer overlying the carrier wafer, wherein the conducting material layer is extended to overly the sidewalls of the through-holes; patterning the conducting material layer into a plurality of conducting layers which are separated from each other and do not contact with the predetermined scribe lines; providing a plurality of chips each having a first electrode and a second electrode; respectively disposing the chips on the corresponding regions, wherein at least one of the chips is disposed on each of the regions, and the first electrode and the second electrode of each of the chips are electrically connected to two of the conducting layers in the regions where the chips are located, respectively; and dicing the carrier wafer along the predetermined scribe lines to separate a plurality of chip packages. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
