Abstract:
A method for providing semiconductor components on a silicon wafer comprising the following steps:providing a silicon wafer having a front and back surface; photolithographic patterning of the back surface of the silicon wafer with semiconductor components, wherein each of the semiconductor components are connected to a frame by holder means provided at one side of said semiconductor components, wherein said semiconductor components and said holder means are formed of the same material and said frame forms a unit to which all semiconductor components are connected by said holder; producing of a desired breaking point between the frame and each of said semiconductor components on said holder by an etching operation and stopping the etching operation before cutting through the silicon wafer to thereby define a breaking point; and thereafter, opening an area around said semiconductor components through said silicon wafer and the frame by photolithographic patterning of one of the silicon wafer front surface and back surface with subsequent chemical etching.
