Abstract: A conformal, substantially uniform thickness layer of photoresist is deposited on a semiconductor wafer by causing photoresist solids to "sediment" out of solution or suspension. Generally, the more conformal the layer, the more uniform the reflectance of the layer and the less variation in underlying feature critical dimension (cd).

In the case of a point-by-point lithography process, such as e-beam lithography, the thickness/reflectance variations can be mapped, and exposure doses adjusted accordingly.

Abstract: A method and an apparatus are disclosed for preventing the formation of humps along the edge of substrates while being spin coated. Said humps are especially observed in edge rinsing substrates that are being coated with spin-on-glass (SOG) and state of the art photoresists. The edge rinse is usually directed at the edge of the substrate at a certain angle from the vertical axis of the rotating substrate.

A novel technique is proposed where the formation of humps is prevented by directing a jet stream of gas at the hump. The jet is placed along the plane of the spinning substrate, and behind the rinse nozzle in the direction of the spin.
