Embodiment Construction

[0034] figure 1 A schematic top view of an apparatus 1 for processing photolithographic masks 2 for the manufacture of semiconductor wafers is shown. The device 1 has a treatment vessel 4 with a side wall 5 which tapers conically at least in an upper region 7 to form an upper circular inlet / outlet opening 8 . The bottom of the treatment container 4 is formed by a corresponding floor, which is fastened together with the side wall panels 5 on a fastening plate 10 . The upper inlet / outlet opening 8 can be closed by a corresponding cover, not shown in detail. In the conical part 7 of the side wall 5 a number of through-holes 12 are provided for the passage of different treatment systems, in particular feed lines for different liquids.

[0035] Inside the processing container 4 is provided with a rotatable receiving device 15, the device according to figure 1 Four support elements 17 are shown. The receiving device 15 is rotatable by means of a shaft passing through the contain...

Abstract

The aim of the invention is to achieve a rapid, homogeneous application of a liquid with as little force as possible to a substrate. To achieve this, the invention provides a nozzle assembly (22) for applying a liquid to a substrate, said assembly having a nozzle body (26) comprising a plurality of nozzles (36) that are substantially arranged in a line and a guide plate (28) that extends essentially in a vertical direction with a straight lower edge. According to the invention, the nozzles (36) above the lower edge are directed towards the guide plate (28) in such a way that a film of liquid forms on the guide plate (28) and flows over the lower edge (64).

Description

technical field [0001] The present invention relates to a nozzle arrangement for applying a liquid to a substrate. Background technique [0002] In many applications, especially in the manufacture of wafers and photolithographic masks, it is necessary to apply a liquid layer on a wafer or a mask, for example as a revealing agent, for processing the substrate. [0003] This has historically been accomplished with a single nozzle directed at the substrate, which is scanned or swept across the mask or wafer in a grid-like manner to wet the entire substrate surface. Another solution that has been considered is the use of a plurality of nozzles arranged next to one another, which are directed at the substrate surface and wet the entire substrate within a single scanning process. [0004] If the liquid to be applied is, for example, a developing liquid, which is used in microlithographic development processes, it is important for the quality of the final product that the The sam...
