Claim:
A lead frame, comprising: a frame body that defines an internal region that is rectangular in shape and has four corners, the frame body extending in a first plane and having a first line that runs diagonally across the internal region between first opposite corners of the internal region, the internal region comprising first and second sub-regions that are separated from each other by the first line; a plurality of leads that extend from the frame body; a first stage being disposed in the first sub-region and extending in a second plane that is parallel to the first line and tilts from the first plane, and the first stage being connected to the frame body so as to be distanced from the first line; and a second stage being disposed in the second sub-region and extending in a third plane that is parallel to the first line and tilts from the first plane and the second plane and the second stage being connected to the frame body so as to be distanced from the first line, wherein the first and second stages are disposed symmetrically to each other with reference to a reflection-symmetric axis that is aligned to the first line.
