Abstract: Various embodiments of the present disclosure are directed towards a semiconductor structure (e.g., an integrated circuit (IC) die) comprising an enhanced cap layer for pad oxidation prevention, as well as a method for forming the IC die. An interconnect pad overlies a substrate at a top of an interconnect structure, and a bond structure overlies and extends from a surface of the interconnect pad. A cap layer and an etch stop layer overlie the surface around the bond structure. Further, the cap layer separates the etch stop layer from the interconnect pad and is soft. Soft may for example, refer to a hardness less than silicon nitride and/or less than the etch stop layer. Because the cap layer is soft, a probe may be pushed through the cap layer to the interconnect pad for testing without first forming a pad opening exposing the interconnect pad.

Abstract: In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and/or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.
