Silicon Nanowires (SiNWs) are used in several applications such as converting chemical energy and temperature gradient in to electrical energy. SiNWs could be manufactured in several different processes depending on what final product one wants to achieve. In this experiment we are interested in fabricating SiNWs that have separations of about 100nm and a diameter of about 40nm using the process of chemical wet etching. We face a real issue during the last few stages of the manufacturing process when trying to transfer an alumina template floating in buffer solution into an acetone solution then deposit it on Silicon. The purpose of this project was to create a mechanical system that would make this process easier to carry out. To achieve this goal, a simple system was designed and rapid prototyped for testing. The mechanical system behaved as originally predicted; however, there is still some stability issue that needs further investigation.
