Project supported by the National High-Tech Research and Development Program of China (No.2008AA031402)
A lithography-independent and wafer scale method to fabricate a metal nanogap structure is demonstrated. Polysilicon was first dry etched using photoresist (PR) as the etch mask patterned by photolithography. Then, ...
