초록
Si 이방성 에칭 용액인 EPW(Ethylenediamine, Pyrocatechol, Water) 용액내에서 potentiostat를 이용한 cyclic polarization 방법으로 양극 산화막의 연구를 수행하였다. p-Si 및 n-Si에서 양극 산화막의 breakdown potential은 동일한 값을 보였으며,
We have studied the anodic oxidation of silicon in the anisotropic etchant of EPW(Ethylenediamine, Pyrocatechol and Water) solution using the cyclic polarization technique. The samples have been characterized by means of X-ray photoelectron spectroscopy(XPS) and secondary ion mass spectrometry (SIMS). The results of cyclic polarization experiments show that the anodic oxides formed on p- and n-type silicon wafers break down at the same potential while breakdown does not occur up to open circuit potential in the case of
