Abstract: A surface-mount device platform includes a surface-mounting region, a connection region, and a bendable region therebetween, each including a respective part of a base substrate. The base substrate includes electrically-conductive layers interspersed with electrically-insulating build-up layers. Each of the surface-mounting region, the connection region, and the bendable region spans between a bottom substrate-surface and a top substrate-surface of the base substrate. The surface-mounting region further includes an electrically-insulating first top rigid-layer, and device bond-pads exposed on a top surface of the first top rigid-layer facing away from the top substrate-surface in the surface-mounting region.

Abstract: A cavityless chip-scale image-sensor package includes a substrate, a microlens array, and a low-index layer. The substrate includes a plurality of pixels forming a pixel array. The microlens array includes a plurality of microlenses each (i) having a lens refractive index, (ii) being aligned to a respective one of the plurality of pixels and (iii) having a non-planar microlens surfaces facing away from the respective one of the plurality of pixels. The low-index layer has a first refractive index less than the lens refractive index. The low-index layer also includes a bottom surface, at least part of which is conformal to each non-planar microlens surface. The microlens array is between the pixel array and the low-index layer.

Abstract: An image sensor package includes a transparent material, and a substrate adhered to the transparent material. An image sensor is disposed on or within the substrate so that the image sensor is disposed between the substrate and the transparent material to receive light from an optical side of the image sensor package through the transparent material. A solder mask dam is disposed between the substrate and the transparent material to form a gap between the image sensor and the transparent material, and the solder mask dam is structured to indicate an orientation of the image sensor, when the image sensor is viewed from the optical side.
