  • METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE USING SUFFRAGE TREATMENT PROCESS
    Publication number: 20240006190
    Abstract: A method of manufacturing a semiconductor device includes forming a channel layer on a substrate, forming a mask on the channel layer, surface-treating an exposed surface of the channel layer exposed from the mask, forming an electrode on the exposed surface of the channel layer, and removing the mask. The channel layer includes a two-dimensional material, and the surface-treating of the exposed surface of the channel layer includes surface-treating the exposed surface of the channel layer with HCl.
