Abstract:
PURPOSE: A doping method of a transistor comprising carbon nano tube is provided to easily manufacture a p-type transistor and an n-type transistor according to needs. CONSTITUTION: A field effect transistor(200) includes a source, a drain, a carbon nano tube, and a gate. The carbon nano tube is a channel of the source and the drain. A first voltage is applied to the gate. An ion is absorbed on a surface of the carbon nano tube(20). In the absorbing step, nitronium hexafluoro antimonate solution is contacted on the surface of the carbon nano tube. The solution which is not absorbed on the surface of the carbon nano tube is removed. The ion is absorbed on the surface of the carbon nano tube by drying the substrate.

PURPOSE: A static random access memory(SRAM) using a carbon nanotube thin film is provided to maintain the characteristic uniformity of an SRAM by including a transistor in which channels are composed of carbon nanotube thin films. CONSTITUTION: A first SRAM includes a first transistor to a sixth transistor(Q1 to Q6). The first transistor and the second transistor form a first inverter(40). The third transistor and the forth transistor form a second inverter(42). The first inverter and the second inverter form a flip-flop circuit. The gate of the fifth transistor is connected with a word-line(W). One end of the sixth transistor is connected with a second bit-line(B2).

Abstract:
Disclosed is a method for preventing charge accumulation in a semiconductor device manufacturing process. According to one embodiment of the present invention, the method for preventing charge accumulation includes the steps of: forming a material layer on a substrate and patterning (processing) the material layer; and forming a graphene layer on the upper part or the lower part of the material layer before the material layer is patterned. The substrate can be an insulating substrate. Also, the substrate can be a laminate with a multi-layered structure.
