摘要:
A field emitter includes a cathode, a field emission point part, a first anode, a charge storing plate, and a second anode. The field emission point part faces the first anode and is disposed at a first surface of and electrically connected to the cathode. The charge storing plate is disposed at a second surface, opposite the first surface, of the cathode. The second anode faces the second surface of the cathode. The charge storing plate is interposed between the second anode and the second surface of the cathode. Even if substantially the same electric field is formed in the field emitter as in a field emitter without the charge storing plate, the field emitter having the charge storing plate induces a more effective field emission current than the field emitter without the charge storing plate.

A plasma etching method using selective polymer deposition, and a method of forming a contact hole using the plasma etching method are provided. The plasma etching method uses a method of reinforcing an etch mask by selectively depositing polymer on only a photoresist pattern, which is an etch mask. That is, a dielectric film is plasma etched for a predetermined period of time using the photoresist pattern as an etch mask, and polymer is selectively deposited on only the photoresist pattern which is thinned by plasma etching, thereby forming a polymer layer. Following this, the dielectric film is plasma etched using the photoresist pattern and the polymer layer as a mask. Thus, dielectric film etching providing high resolution and an excellent profile can be performed using the thinned photoresist pattern as a mask, and a contact hole and a self-aligned contact hole each having a very high aspect ratio, and a self-aligned contact hole having an excellent profile, can be formed.
