REDUCING LEAD STRESS IN MICRO-ELECTRONIC PACKAGES

摘要

Consistent with an example embodiment, there is a semiconductor device that comprises a lead frame assembly having a non-conductive material (NCM) sheet placed on a location of the lead frame assembly. A device die having a length, width, and thickness, is attached to the NCM sheet, the device die being attached to the NCM with an adhesive. The NCM sheet has a length and width greater than the length and width of the device die and the NCM sheet has a thickness less than the thickness of the device die. The NCM sheet mitigates wire bond lifting at device die bond pads by reducing bouncing of the wire bond leads owing to stress and movement of the lead frame assembly underneath the device die.
