Abstract:
1. A semiconductor package, comprising: a curved body including a center region, a first end region, and a second end region, the second end region being opposite the first end region and an intermediate center region, the curved body having a first inflection point at the center region, a second inflection point at the first end region and a third inflection point at the second end region, the center region having a convex curvature with a minimal extremum at the first inflection point, the first end region having a concave curvature with a maximal extremum at the second inflection point and the second end region having a concave curvature with a maximal extremum at the third inflection point; and a plurality of semiconductor die each having a first side attached to an upper surface of the curved body between the maximal extrema, and a second side opposing the first side, wherein the second side of each semiconductor die faces away from the curved body.
