A field effect transistor with multi-width electrode structure and manufacturing the same are provided in the present invention. In the field effect transistor, an epitaxial layer set on a substrate is set a trench which has an oxide layer. The oxide layer has a first electrode portion which has a first width and a first height and a second electrode portion which has a second width and a second height. A gate oxide layer which covered the oxide layer and the second electrode portion has a gate portion which has a third width. The epitaxial layer has a body region and a source region. The body region and the source region are adjacent to the gate portion and covered by an interlayer dielectric. A source contact is covered the body region and the interlayer dielectric and contact the source region. The first height is more than the second height or equals to the second height, the first width is smaller than the second width, and the second width is smaller than the third width.
