    Abstract: Disclosed is a shallow trench isolation structure having an air gap for suppressing the dark currents and cross-talk which occur in CMOS image sensors. The shallow trench isolation structure suppresses photons injected from neighboring pixels and dark current, so that high-quality images are obtained. Since impurities are removed from a p type ion implantation region for a photodiode when an inner wall oxide layer is etched to form the air gap, the p type ion implantation region has a uniform doping profile, thereby suppressing the diffusion of electrons towards the surface and achieving an image having a high quality.

  • Patent number: 8956949
    Abstract: Disclosed are a structure for electrical signal isolation between adjacent devices situated in a top semiconductor layer of the structure and an associated method for the structure's fabrication. The structure includes a trench extending through the top semiconductor layer and into a base oxide layer below the top semiconductor layer. A handle wafer is situated below the base oxide layer and a void is disposed in the handle wafer below the trench. A bottom opening of the trench connects the main body of the trench with the void forming a continuous cavity including the main body, the bottom opening of the trench, and the void such that the void improves electrical signal isolation between the adjacent devices situated in the top semiconductor layer. Unetched portions of the handle wafer are then available to provide mechanical support to the top semiconductor layer.
