Patent ID: 10978513

Abstract:
Provided are a complementary carbon nanotube field effect transistor (CNT-FET) and a manufacturing method thereof. In particular, provided is carbon nanotube-based type conversion technology (p-type→n-type) using a photosensitive polyvinyl alcohol polymer which can be selectively cross-linked at a desired position based on a semiconductor standard process, i.e., photolithography. The CNT-FET includes: a substrate; a first channel layer formed on the substrate and made of a carbon nanotube; a first source electrode formed at one side of the first channel layer and made of a conductive material; a first drain electrode formed at the other side of the first channel layer and made of a conductive material; a conversion induction layer formed on the first channel layer between the first source electrode and the first drain electrode and configured to convert the first channel layer from a p-type to an n-type; a protective layer configured to protect the conversion induction layer; and a first gate electrode formed on the protective layer.
