摘要:
A method of forming a dual gate fin-type field effect transistor (FinFET) structure patterns silicon fins over an insulator and patterns a gate conductor at an angle to the fins. The gate conductor is formed laterally adjacent to and over center portions of the fins. The gate conductor is planarized such that the gate conductor is separated into distinct gate conductor portions that are separated by the fins. These gate conductor portions include front gates and back gates. The front gates and the back gates alternate along the structure, such that each fin has a front gate on one side and a back gate on the opposite side. Then front gate wiring is formed to the front gates and back gate wiring is formed to the back gates.
摘要:
A method and structure for a programmable circuit that includes a magnetic device having a reluctance which is alterable. The magnetic device can be programmed into one of three magnetic field orentations or states. Conventional VLSI fabrication steps are used for compatability with low-k dielectric Back-End-Of-Line (BEOL) processing.
摘要:
Breakdown and latch-up of field effect transistors integrated with non-volatile semiconductor memory cells requiring voltages higher than logic level voltages for write and erase operations is avoided while limiting process complexity and constraints and increasing potential integration density by using thin film transistors for high voltage switching and isolating the thin film transistors from the substrate by forming the thin film transistors on isolation structures extending between or over elements formed at a surface of a substrate or semiconductor layer. Geometry and doping levels of the thin film transistors is thus made independent of geometry and doping levels of the non-volatile semiconductor memory cells and other field effect transistors operating at lower logic-level voltages. In particular, the thickness of a doped semiconductor layer in which an impurity well may be formed can be determined in a manner to optimize performance of transistors operating at logic level voltages rather than the breakdown voltage which must be withstood by transistors used for controlling write and erase operations of the non-volatile memory cells.
