Methods of dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. In an example, a method of dicing a semiconductor wafer having a plurality of integrated circuits on a front side of the semiconductor wafer includes adhering a back side the semiconductor wafer on the dicing tape of a substrate carrier. Subsequent to adhering the semiconductor wafer on a dicing tape, the dicing tape is treated with a UV-cure process. Subsequent to treating the dicing tape with the UV-cure process, a dicing mask is formed on the front side of the semiconductor wafer, the dicing mask covering and protecting the integrated circuits. The dicing mask is patterned with a laser scribing process to provide gaps in the dicing mask, the gaps exposing regions of the semiconductor wafer between the integrated circuits. The semiconductor wafer is plasma etched through the gaps in the dicing mask layer to singulate the integrated circuits.

Methods of dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. In an example, a method of dicing a semiconductor wafer having a plurality of integrated circuits involves forming a mask above the semiconductor wafer, the mask composed of a layer covering and protecting the integrated circuits. The mask is then patterned with a top hat laser beam profile laser scribing process to provide a patterned mask with gaps, exposing regions of the semiconductor wafer between the integrated circuits. The semiconductor wafer is then plasma etched through the gaps in the patterned mask to singulate the integrated circuits.

Improved wafer coating processes, apparatuses, and systems are described. In one embodiment, an improved spin-coating process and system is used to form a mask for dicing a semiconductor wafer with a laser plasma dicing process. In one embodiment, a spin-coating apparatus for forming a film over a semiconductor wafer includes a rotatable stage configured to support the semiconductor wafer. The rotatable stage has a downward sloping region positioned beyond a perimeter of the semiconductor wafer. The apparatus includes a nozzle positioned above the rotatable stage and configured to dispense a liquid over the semiconductor wafer. The apparatus also includes a motor configured to rotate the rotatable stage.

Embodiments of the invention generally relate to solar cells having reduced carrier recombination and methods of forming the same. The solar cells have eutectic local contacts and passivation layers which reduce recombination by facilitating formation of a back surface field (BSF). A patterned aluminum back contact is disposed on the passivation layer for removing current form the solar cell. The patterned back contact reduces the cost-per-watt of the solar cell by using less material than a full-surface back contact. The methods of forming the solar cells include depositing a passivation layer including aluminum oxide and silicon nitride on a back surface of a solar cell, and then forming openings through the passivation layer. A patterned aluminum back contact is disposed on the passivation layer over the holes, and thermally processed to form a silicon-aluminum eutectic within the openings.
