Abstract:
A method for fabricating a semiconductor device heat spreader, comprising:providing a unitary piece of metallic material; stamping the unitary piece of metallic material to form a unitary heat spreader having: an upper heat dissipation region; a lower substrate contact region; supports connecting the upper heat dissipation region and the lower substrate contact region; and a recess within the supports and the upper and lower regions for receiving a semiconductor device therein; and forming, in the lower substrate contact region, at least one contact pad having a deeper extent than the lower substrate contact region for contacting a substrate and supporting the lower substrate contact region at a predefined clearance above the substrate to accommodate a layer of adhesive/thermal interface material therebetween and to create a constant bond line thickness therebetween for the layer of adhesive/thermal interface material.
