Abstract
The present disclosure provides methods of manufacturing porous silicon structures having controlled sizes, shapes, and porosity by using a series of protective layers and selective etching steps. A benefit of the methods disclosed herein can be providing microfabrication and nanofabrication methods that are capable of provide porous silicon structures having sizes, shapes, and porosity that are more tightly controlled by avoiding inadvertently etching parts of the silicon structures during the fabrication process.
