ABSTRACT:
A lead frame structure of a semiconductor package including a plurality of leads, a respective dam bar extended from at least one of the plurality leads toward an adjacent lead and having a certain distance provided between the respective dam bar and the adjacent lead, and an insulating adhesive member is filled between the leads and the dam bars. The lead frame structure prevents leads from bending or twisting.
