Abstract
This paper presents a mask-less lithography process using direct-write nanofibers via near-field electrospinning on flexible substrate as masking materials in processes such as lift-off, wet-etching and dry-etching. The polymer fibers have diameter of sub-micrometer to micrometer with good adhesion to substrate and chemical sustainability. Key demonstrations successfully realized in this work include sub-micrometer metal gaps, micro heaters and definition of graphene structures on flexible substrates. As such, this direct-write lithography technique could find applications in low-cost microelectronics, including flexible electronics.
