    摘要: A method for forming a semiconductor devices structure includes providing a semiconductor substrate, forming a deep trench continuously in the substrate to separate a first region from a second region, and then forming a silicon-on-insulator region in the first region while maintaining a non-silicon-on-insulator region in the second region. The deep trench has a depth which is at least as deep as the depth of the buried oxide in the substrate. The invention also includes a device structure resulting from the method.

    摘要: A structure forming a metal-insulator-metal (MIM) trench capacitor is disclosed. The structure comprises a multi-layer substrate having a metal layer and at least one dielectric layer. A trench is etched into the substrate, passing through the metal layer. The trench is lined with a metal material that is in contact with the metal layer, which comprises a first node of a capacitor. A dielectric material lines the metal material in the trench. The trench is filled with a conductor. The dielectric material that lines the metal material separates the conductor from the metal layer and the metal material lining the trench. The conductor comprises a second node of the capacitor.

    摘要: Embedded DRAM MOSFETs including an array NFET having a gate stack comprising a high-K dielectric layer upon which is deposited a first metal oxide layer (CD1) then a conductive layer (TiN), and then a polysilicon layer (Poly). A logic PFET having substantially the same gate stack as the array NFET, and a logic NFET having a third gate stack comprising the high-K dielectric layer upon which is deposited the conductive layer (TiN) and then the polysilicon layer (Poly), without the first metal oxide layer (CD1) between the high-K dielectric layer and the conductive layer (TiN). The array NFET may therefore have a higher gate stack work function than the logic NFET, but substantially the same gate stack work function as the logic PFET.

    摘要: A deep trench is formed to a depth midway into a buried insulator layer of a semiconductor-on-insulator (SOI) substrate. A top semiconductor layer is laterally recessed by an isotropic etch that is selective to the buried insulator layer. The deep trench is then etched below a bottom surface of the buried insulator layer. Ion implantation is performed at an angle into the deep trench to dope the sidewalls of the deep trench beneath the buried insulator layer, while the laterally recessed sidewalls of the top semiconductor layer are not implanted with dopant ions. A node dielectric and trench fill materials are deposited into the deep trench. A buried strap has an upper buried strap sidewall that is offset from a lower buried strap sidewall and a deep trench sidewall.

    摘要: Disclosed herein are embodiments of a deep trench capacitor structure and a method of forming the structure that incorporates a buried capacitor plate contact that is simultaneously formed using an adjacent deep trench. This configuration eliminates the need for additional photolithographic processing, thereby, optimizing process windows. This configuration further eliminates the need to form the deep trench capacitor through an N-doped diffusion region connector and, thereby, allows for greater design flexibility when connecting the deep trench capacitor to another integrated circuit structure (e.g., a memory cell or decoupling capacitor array). Also, disclosed herein are embodiments of another integrated circuit structure and method, and more specifically, a memory cell (e.g., a static random access memory (SRAM) cell)) and method of forming the memory cell that incorporates one or more of these deep trench capacitors in order to minimize or eliminate soft errors.
