| Summary: | In past decades, silicon is commonly used in the semiconductor industry. Recently, researcher extensively studied the porous silicon produced by electrochemical etching because there is possibility to develop a new approach in developing optoelectronic devices, solar cell and sensor. In this research, the Porous Silicon (PS) was fabricated by chemical etching method on the P-type silicon wafer in the mixture of hydrofluoric acid (HF) etchant with different concentration of nitric acid(HN03) of 20%, 40%, 65% and at different etching time of 5, 10, 15, 20, 25 minutes. |
