Claim of US Patent No. 11,032,942

1. A thermally conductive heat transfer interface structure comprising a substrate having a first surface and a second surface and a plurality of raised features formed on at least one of the first surface and the second surface of the substrate, the raised features being deformable under a compressive force, wherein at least some of the raised features each have an opening through a respective end portion thereof;wherein a thickness of a wall of a raised feature of the at least some of the raised features at said end portion is smaller than a thickness of the wall of the raised feature at an intermediate portion of the raised feature; and
wherein, one or more raised features from the plurality of the raised features each comprise a first height corresponding to a first location on the end portion thereof and a second height corresponding to a second location on the end portion thereof, wherein each one of the first height and the second height is a distance from a plane defined by the substrate to a parallel plane passing through a location on the end portion.
