Abstract:
A multiple tip nozzle for applying a material onto a photoresist material layer disposed on a substrate, the nozzle comprising:a nozzle body;a developer distribution line enclosed in the nozzle body, the developer distribution line being adapted to be connected to a supply of developer material on a first end and a removal device on a second end wherein developer material is provided to the developer distribution line from the supply of developer material and excess developer material is removed by the removal device;a plurality of developer nozzle tips extending from the nozzle body and being in a communicative relationship with the developer distribution line;a washing solution distribution line enclosed in the nozzle body, the washing solution distribution line being adapted to be connected to a supply of washing solution material on a first end and a removal device on a second end wherein the washing solution is provided to the washing distribution line from the supply of washing solution material and excess washing solution material is removed by the removal device;a plurality of washing solution nozzle tips extending from the nozzle body and being in a communicative relationship with the washing solution distribution line, wherein the developer distribution line and the washing solution distribution line are substantially isolated from one another and the nozzle is adapted to apply onto the photoresist material layer both a developer material and a washing solution material at different time intervals;a developer input supply tube connected at a first end to the developer distribution line and adapted to be connected to a second end by the supply of developer material; anda washing solution input supply chamber connected at a first end to the washing distribution line and adapted to be connected to a second end by the supply of washing solution material, the washing solution input supply chamber substantially surrounding at least a portion of the developer input supply tube.
