Abstract:
1. A method for manufacturing semiconductor packages comprising following steps: providing a wafer defining an active surface and a back surface opposite to the active surface, the wafer having a plurality of chips and a plurality of scribe lines formed among the chips wherein each chip has an optical component disposed on the active surface and a plurality of bonding pads disposed on the active surface and electrically connected to the optical component; forming a plurality of first holes through the bonding pads on the chips of the wafer; forming a conductive material within the plurality of first holes to form a plurality of via holes electrically connected to the bonding pads; providing a lid to be attached to the wafer and cover the active surface of the wafer; forming a plurality of metal traces on the back surface of the wafer, the metal traces being electrically connected to the via holes and defining a plurality of solder pads thereon; forming a plurality of adhesive rings respectively around the optical components for attaching the lid to the wafer, wherein each adhesive ring is made of an adhesive material having a plurality of spacers mixed thereinto; and cutting the wafer to form a plurality of individual semiconductor packages.
