The directed self-assembly process was proposed as the next-generation semiconductor manufacturing process, and much research has been conducted. However, as research for assembling nanomaterials at a certain location has such low precision, much improvement must be needed. Prof. Gira Yi’s research project aims to manufacture distributable transistor devices and use DNA to assemble them at a certain location.

Research on the fabrication of colloidal transistors and self-assembly based on DNA can be utilized on a two-dimensional plane to efficiently improve the device manufacturing process, which was previously difficult to manufacture using a top-down method. Plus, as they can be applied to the assembly of DNA-mediated nanomaterials, they can be used for various purposes, e.g., the nano-optical device, solar cells (photonic crystal), smart windows, and quantum computer manufacturing processes.

Successful research results can be applied to various industries by replacing the etching process. Selectively assembling transistors on patterned substrates using DNA was evaluated as engaging and highly feasible.
