Patent ID: 8017998

Claim:
A semiconductor-on-insulator structure configured to attract contaminants, comprising: contaminant attractor regions formed using ion implantation into a semiconductor layer of the semiconductor-on-insulator structure; the semiconductor layer located above a buried insulator layer of the semiconductor-on-insulator structure; the contaminant attractor regions being spaced away from active regions of the semiconductor-on-insulator structure; tiles located on an upper surface of the buried insulator layer; the contaminant attractor regions formed adjacent to, in close proximity to, or in the tiles; the contaminant attractor regions for gettering at least a portion of the contaminants located in the active regions to the contaminant attractor regions; at least one dielectric layer laterally adjacent to the tiles and disposed on the upper surface of the buried insulator layer; and the at least one dielectric layer at least inhibiting lateral migration of contaminants to the active regions.
