    Abstract: PROBLEM TO BE SOLVED: To provide a vertical type field effect transistor array improved in performance, and a method of manufacturing the same.
    SOLUTION: Each vertical part of each semiconductor pillar in a semiconductor pillar array has a line width greater than a separation distance to a neighboring semiconductor pillar. Alternatively, the array may arbitrarily includes a semiconductor pillar having a different line width within the restriction of the line width and the separation distance. A method of manufacturing the array of the semiconductor pillar uses a pillar mask layer created into a minimum dimension using photolithography, at least one of spacer layers of which is increased in an annular manner before it is used as an etching mask.
