    摘要: The invention relates to a method for selective etching of SiC, the etching being carried out by applying a positive potential to a layer (3; 8) of p-type SiC being in contact with an etching solution containing fluorine ions and having an oxidising effect on SiC. The invention also relates to a method for producing a SiC micro structure having free hanging parts (i.e. diaphragm, cantilever or beam) on a SiC-substrate, a method for producing a MEMS device of SiC having a free hanging structure, and a method for producing a piezo-resistive pressure sensor comprising the step of applying a positive potential to a layer (8) of p-type SiC being in contact with an etching solution containing fluorine ions and having an oxidising effect on SiC.

    摘要: Systems and methods for etching topographic features in non- crystalline or metallic substrates are provided. A protective material is placed and patterned on a surface of the substrate to define exposed and protected regions of the substrate for etching in a liquid etchant having etching rates that are thermally activated. A nonuniform temperature profile is imposed on the substrate so that the temperatures and hence the etching rates at surfaces in the exposed regions are higher than those in the protected regions. Arrangements for imposing the nonuniform temperature profile include heating designated portions of the substrate with light radiation. Alternatively, the non-uniform temperature profile is developed as etching progresses by passing current pulses through the substrate in a manner that causes geometrically non-uniform heating of the substrate.
