Patent DE-4020724-A1 (DE)
Inventor: SCHWEIKHARDT JOERG DIPL PHYS D
IPC: H01L21/306
Filed: 1990-06-29
Abstract: The proposal is for a process for structuring a single-crystal silicon substrate by wet-chemical etching with an anisotropic etching solution. Here, a masking coating is applied to the silicon substrate and structured by the photo-masking method whereby apertures are produced in the masking layer through which the anisotropic etching solution may act on the silicon substrate. A structured aperture in the masking layer is to be made in the region of the silicon substrate where a recess is to be etched. This consists of at least two partial apertures separated by thin pegs formed in the masking coating. A partial recess in the silicon substrate corresponding to each partial aperture is made by etching through the structured aperture. By continuing the etching process, the thin pegs formed in the masking layer are then undermined so that the partial recesses unite to form one total recess. The bottom of this recess is then smoothed.
