    Abstract: A method of thinning wafer is disclosed. A wafer has an active surface and a back surface is provided. A plurality of protruding components may be disposed on the active surface. The wafer is placed in a mold and a polymeric material is formed in the mold to cover at least the active surface of the wafer. The polymeric material is cured and the mold is removed. The back surface of the wafer is ground to thin the wafer. The polymeric material is removed to expose the active surface of the wafer and the protruding components disposed on the active surface. The polymeric material is allowed to cover the active surface of the wafer and the protruding components through the mold; accordingly, the stress produced during the grinding can be distributed uniformly on the wafer, and the wafer warpage, breakage, or collapse, or the protruding component peeling can be avoided.

    Abstract: A method for marking chip scale packages at the wafer level is provided. First, a positioning step is performed to determine the position of a plurality of semi-finished chip scale packages formed on a wafer. Each of the semi-finished chip scale package includes a plurality of terminals for making external electrical connections and each die has a plurality of bonding pads on an active surface thereof. The bonding pads are electrically connected to the respective terminals wherein a backside surface of the die is exposed from a surface of the respective semi-finished chip scale package. The exposed backside surface of the die is then marked by ink-jet printing. Afterward, the ink marks on the dice are cured. Finally, the wafer is diced to obtain a plurality of separated chip scale packages.

    Abstract: A wafer-level method for manufacturing a chip package structure is disclosed. A wafer comprises a first surface and a second surface opposite thereto. The first surface has chip units disposed thereon to define scribe lines. An adhesive material is disposed between the first surface and the transparent glass for adhering the wafer to a transparent glass and leaving no gap between the first surface and the transparent glass. The wafer is vertically cut from the second surface corresponding to each scribe line of the first surface to the encapsulation adhesive material for forming scribe grooves, and then the second surface is coated with an encapsulation material for filling the scribe grooves. After removing the adhesive material and the transparent glass, the encapsulation material in each of the scribe grooves is vertically cut from the first surface, so as to form chip package structures.

    Abstract: A wafer laser-marking method is provided. First, a wafer having a first surface (an active surface) and a second surface (a back surface) opposite to each other is provided. Next, the wafer is thinned. Then, the thinned wafer is fixed on a non-UV tape such that the second surface of the wafer is attached to the tape. Finally, the laser marking step is performed, such that a laser light penetrates the non-UV tape and marks a pattern on the second surface of the wafer. According to the laser-marking method of the embodiment, the pattern is formed by the non-UV residuals left on the second surface of the wafer, and the components of the glue residuals at least include elements of silicon and carbon.
