Abstract: One embodiment of the present invention provides a method of manufacturing an electronic device using a cyclic doping process including i) an operation of forming a unit transfer thin film including a two-dimensional material on a transfer substrate, ii) an operation of doping the unit transfer thin film in a low-damage doping process, iii) an operation of transferring the unit transfer thin film doped according to the operation ii) on a transfer target substrate, and iv) an operation of repeatedly performing the operations i) to iii) several times to reach a target thickness.

Abstract: The present invention relates to an apparatus for heat-treating waste matters, and more particularly an ecological apparatus for heat-treating waste matters, which enables waste matters such as various industrial wastes, city-living wastes and various high polymeric chemical wastes to be subjected to heat treatment at a lower temperature under vacuum in a heat-treating vessel without discharging pollutants produced during the heat treatment such as carbon, tar, noxious gases, malodors, and dust by treatment in a filter mechanism.
