Abstract:
1. A package for containing a semiconductor element comprising: a housing containing a semiconductor element; and a pair of positioning holes and a pair of attaching holes respectively provided at opposed side portions of said housing; wherein a line between said pair of positioning holes and a line between said pair of attaching holes intersect with each other substantially at a center of said package and further wherein the line between the positioning holes is skewed with respect to each of four primary side walls of the housing and the line between the attaching holes is skewed with respect to each of the four primary side walls such that the line between the positioning holes and the line between the attaching holes are each neither parallel nor perpendicular to any of the primary side walls, and further wherein the line between said pair of positioning holes is a straight line between centers of the positioning holes and is skewed with respect to each of four primary side walls of the housing and the line between said pair of attaching holes is a straight line between the centers of the attaching holes and is skewed with respect to each of four primary side walls such that the line between the positioning holes and the line between the attaching holes are each neither parallel nor perpendicular to any of the primary side walls, and neither line is located at a center line of the device which is perpendicular to the primary side walls.
