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.
