    Abstract: PROBLEM TO BE SOLVED: To provide a lateral MOS transistor for intermediate power for which access resistance to a source and a drain is reduced.
    SOLUTION: A MOS power transistor is formed in an epitaxial layer of a first conductivity type. The MOS power transistor is formed on the front surface of a heavily-doped substrate of the first conductivity-type and includes alternate drain and source arrays of a second conductivity-type separated by a channel, conductive fingers, covering source fingers and drain fingers and a second metal layer connecting all drain metal fingers and covering the entire source/drain structure. Each source finger includes a heavily-doped region of the first conductivity-type, in contact with the epitaxial layer and with the corresponding source finger, and the rear surface of the substrate is coated with a source metallization.
