In this study, to obtain the width effect on tensile property for NiCo thin film, the specimens were fabricated by etching process to make a smooth specimen of 2000 ㎛ length with 300 ㎛ of gage length, 10 ㎛ thickness and 3 kinds of width, 50, 100, 200 ㎛. These specimens had brittle characteristic, and values about 161±5.1 ㎬ of Young’s modulus without effect of width. There were tendency that specimens with smaller width have high fracture strength. The fracture strength for the width of 50, 100, 200 ㎜ were 1415.9±68.29, 1171.2±68.74, 1093.3±89.51 ㎫, respectively.
