Microfabrication and Nanofabrication of a device begins with designing the entire process. Typically a new student of microfabrication/nanofabrication will receive step by step instructions from their advisor, post-doctorate or senior student. Nanofabrication processes is as much an art as it is a science. While theory helps us imagine, explain and predict what will happen, practical knowledge and experiences enable us to masterfully and reliably craft devices.
