20210335602 · 2021-10-28 ·

In some embodiments, the present disclosure relates to method for trimming and cleaning an edge of a wafer. The method includes trimming an outer edge portion of the wafer with a blade along a continuously connected trim path to define a new sidewall of the wafer. The trimming produces contaminant particles on the wafer. Further, the method includes applying deionized water to the new sidewall of the wafer with water nozzles to remove the contaminant particles. The method also includes applying pressurized gas to the wafer at a first top surface area of the wafer with an air jet nozzle. The pressurized gas is directed outward from a center of the wafer to remove remaining contaminant particles. The applying of deionized water and the applying of pressurized gas are performed in a same chamber as the trimming.

WAFER CLEANING METHOD AND APPARATUS THEREFORE

The present invention relates to a method for treating the surface of a wafer with multiple liquids, comprising rotating the surface of the wafer and discharging different liquid streams onto the rotating surface in a sequence from separate outlets, wherein the discharge of liquid streams which are contiguous in the sequence overlaps during a transition phase, and wherein during the transition phase the liquid streams merge after exiting said outlets to form a merged liquid stream before impacting the rotating surface. The invention also provides a liquid dispensing device incorporating a housing holding two or more liquid delivery tubes, wherein the tubes' outlets are inwardly angled towards one another, such that in use liquid streams delivered from the outlets of the two or more liquid delivery tubes merge to form a merged liquid stream.

SEMICONDUCTOR WAFER AND METHOD OF WAFER THINNING

A semiconductor wafer has a base material. The semiconductor wafer may have an edge support ring. A grinding phase of a surface of the semiconductor wafer removes a portion of the base material. The grinder is removed from or lifted off the surface of the semiconductor wafer during a separation phase. The surface of the semiconductor wafer and under the grinder is rinsed during the grinding phase and separation phase to remove particles. A rinsing solution is dispensed from a rinsing solution source to rinse the surface of the semiconductor wafer. The rinsing solution source can move in position while dispensing the rinsing solution to rinse the surface of the semiconductor wafer. The grinding phase and separation phase are repeated during the entire grinding operation, when grinding conductive TSVs, or during the final grinding stages, until the final thickness of the semiconductor wafer is achieved.
