Title: Partial layer removal from substrate - with solvent or etchant, using combination of capillary and centrifugal forces
Inventor: BURGER ROBERT
IPC: B05B12/20
Filed: 1992-01-28
Abstract: Partial removal of a thin layer (e.g, of lacquer or metal) from the pref. flat surface of a substrate is carried out by rotating the substrate about a normal to the surface and applying a solvent or etchant to the edge region of the surface so that the solvent or etchant is ejected, together with removed layer material, by centrifugal force from the substrate. (a) the surface is (partially) masked by a patterned mask (31) arranged at a small distance from the surface to form a capillary; (b) the solvent or etchant (38) is supplied while the mask is rotated at a certain speed synchronously with the substrate (13); and (c) after a certain time, solvent or etchant supply is stopped and the solvent or etchant is ejected at an incraesed rotational speed. Appts. for carrying out the above process is also claimed. USE/ADVANTAGE - The process allows treatment of practically any layer structures on substrate of various shapes and produces a very sharp demarcation line between lacquer or metal coated and uncoated surface regions. The process may be used to treat e.g, ceramic substrates with a photoresist or polyimide layer or metallised substrates as used e.g., in LCDs.
