Patent ID: 7270843

Claim:
Method for coating a wafer with a fluid coating from a coating container, wherein the wafer is given an edge coating as well as a coating on its inside surfaces, where said fluid coating is stirred, as repression bodies are elevated and lowered in one or more first areas of said coating container, wherein said wafers in a second area of said coating container are supplied with said edge coating, that said fluid coating is sprayed from below upwards in said wafers, just before said edge coating is carried out, wherein said fluid coating from said repression bodies is pumped diagonally up into said wafers via nozzles for constructing an inside coating on the inside surfaces, wherein the pumping is interrupted almost simultaneously with the edge of the wafer contacting a surface of the fluid coating, and that either a level of the said coating's surface in said coating container's second area is kept stationary or the wafers are kept stationary when the product is being edge-coated.
