Appliance for monitoring of etching activation
A novel appliance for monitoring of wet chemical etch activation was developed at Saarland University. A desired final point of the etch activation (etch stop) can be determined by continual measurement during the wet chemical structure activation. The method is suitable for any plane-parallel substrates which are optically transparent in at least one partition of the spectrum. In particular, the following substrates are of great interest: Si, GaAs, SiC, GaN, Ge, silicon and other III-IV semiconductors.
