Abstract:
PURPOSE: A polyimide polymer including a backbone of triphenylamine is provided to enhance thermal stability of a polymer active layer which is the most important part of a non-volatile memory device, to have various memory properties, to be used in the non-volatile memory device. CONSTITUTION: A polyimide polymer including a backbone of triphenylamine is marked by chemical formula 1. In chemical formula 1, X is -CH-, N, or P and Y is a carboxyl group or a hydroxyl group. A method for manufacturing a polymer memory device comprise a step of forming an active layer on a lower electrode which is formed on a substrate and a step of forming an upper electrode to contact with the active layer. The active layer is comprised of the polyimide polymer.
Abstract:
PURPOSE: A non-volatile memory device is provided to secure the current-voltage switching phenomenon of the device, and to simplify the manufacturing process of the memory device. CONSTITUTION: A non-volatile memory device uses a polyimide polymer containing a carbazole or carbamyl group as a branch, as an organic active layer. The polyimide polymer is marked with chemical formula 1. In the chemical formula 1, R1, R2, R3, R4, R5, and R6 are hydrogen, an alkyl group, an aryl group, a heteroaryl group, an aralkyl group, or a cycloalkyl group. A is either a carbazole group or a carbamyl group. N is an integer, and a repeating unit. A non-volatile memory device comprises a bottom electrode, an organic active layer, and an upper electrode.
Abstract:
PURPOSE: A hemostasis apparatus is provided to accomplish a miniaturization by combining a microwave oscillator and an amplifier with a small resonator. CONSTITUTION: A microwave oscillator(200) generates a microwave signal. An amplifier(300) is arranged between an output terminal of the microwave oscillator and a resonator(400) to amplify the microwave signal. The resonator is driven by a resonant energy of the micro signal. The resonator generates plasma with discharging an inactive gas provided from a gas supply part. The gas supply part(500) provides the inactive gas to the resonator. A hemostasis part(600) centers the plasma on a bleeding part to clot a blood.
