Electroplating Process

In this work, a combined process for simultaneously manufacturing nanoporous silicon (NPS) and its metallization was present. The key point is the utilization of adjust electrolyte of silver nitrate and the electroplating timing after the NPS etching process. The current-control mode was used to prepare NPS membrane and the obtained pore-size and pillar-depth were about 0.5 μm and 140 μm, respectively. For clarify the metallization quality of studied process, the semiconductor analyzer was utilized to measured current-voltage (IV) characteristic. Compared to NPS with conventional electroplating process, the contact properties of fabricated sample would be effectively improved by the proposed method. The obtained IV characteristic of sample with combined process shows a larger turn-on current about 277 times than other samples.

Adsorption Phenomena

In this work porous silicon samples obtained by electrochemical etching were investigated. Using scanning probe microscope the morphology of porous silicon samples was studied. To determine the thickness of the porous layer and the pore diameter, micrographs were obtained using a scanning electron microscope. The dimensions of the nanocrystallites were determined from the Raman spectra. For the detection of vapors of organic compounds, planar structures were used. The results of the study confirmed the possibility of using nanoporous silicon as a sensitive material for the determination of acetonitrile and chloroform vapors. It is shown that the adsorption phenomena in porous silicon depend on its structure and morphology. It is established that the humidity of the air when detecting the vapors of organic compounds under investigation has a significant effect on the sensitivity. It is also shown that such structures can be used as instruments for measuring air humidity.
