porous silicon as a sacrificial layer in production of

Unsupported silicon diaphragms formed by grinding exhibit post-grinding shape distortion dependent upon diaphragm thickness and diameter. Such distortion can be eliminated or strongly suppressed by use of a support during the grinding process. Use of porous silicon as in-situ support for 15 – 150 μm thick diaphragms is explained with
