Abstract

We present here design and fabrication of short channel organic thin film transistor with uniform performance and good thermal stability for utilization in neural interface systems. Transistors are fabricated on ultra-thin parylene diX-SR substrate which provides great flexibility and conformability to curvilinear surfaces. With channel length as short as 2μm, transistors show low contact resistance and good mobility in bottom contact architecture for higher operating frequencies. As a crucial factor for sterilization, our transistors demonstrate excellent thermal stability and remain functional up to 170°C. The low operating voltage and their heat durability prospect those devices to serve as an efficient interface to the complex texture of brain tissue for future applications.
