    摘要: A method for forming a diode of a phase change random access memory device includes preparing a semiconductor substrate having a dopant area formed thereon. An insulating layer on the semiconductor substrate is formed and a contact hole is formed by etching a part of the insulating layer such that a specific region of the dopant area is exposed. A silicon layer doped with a first-type dopant is formed in the contact hole. A part of the silicon layer is doped with a second-type dopant source gas through a gas cluster ion beam process.

    摘要: Provided is a method for forming a gate of a non-volatile memory device. A tunneling layer, a charge trapping layer, a blocking layer, and a control gate layer are formed on a semiconductor substrate. A hard mask is formed on the control gate layer. The hard mask defines a region on which a gate is formed. A gate pattern is formed by etching the control gate layer, the blocking layer, the charge trapping layer, and the tunneling layer. A damage compensation layer on a side of the gate pattern is formed using ultra low pressure plasma of a pressure range from approximately 1 mT to approximately 100 mT.

    摘要: A charge trapping device includes a plurality of isolation layers, a plurality of charge trapping layers, a blocking layer, and a control gate electrode. The isolation layers define active regions, and the isolation layers and active regions extend as respective stripes along a first direction on a semiconductor substrate. The charge trapping layers are disposed on the active regions in island forms where the charge trapping layers are separated from each other in the first direction and disposed on the respective active regions between the isolation layers in a second direction perpendicular to the first direction. The blocking layer is disposed on the isolation layers and the charge trapping layers. The control gate electrode is disposed on the charge trapping layer.
