摘要: Disclosed are embodiments of a field effect transistor that incorporates an elongated semiconductor body with a spiral-shaped center channel region wrapped one or more times around a gate and with ends that extend outward from the center region in opposite directions away from the gate. Source/drain regions are formed in the end regions by either doping the end regions or by biasing a back gate to impart a preselected Fermi potential on the end regions. This disclosed structure allows the transistor size to be scaled without decreasing the effective channel length to the point where deleterious short-channel effects are exhibited. It further allows the transistor size to be scaled while also allowing the effective channel length to be selectively increased (e.g., by increasing the number of times the channel wraps around the gate). Also, disclosed are embodiments of an associated method of forming the transistor.

摘要: Disclosed is a CNT technology that overcomes the intrinsic ambipolar properties of CNTFETs. One embodiment of the invention provides either a stable p-type CNTFET or a stable n-type CNTFET. Another embodiment of the invention provides a complementary CNT device. In order to overcome the ambipolar properties of a CNTFET, source/drain gates are introduced below the CNT opposite the source/drain electrodes. These source/drain gates are used to apply either a positive or negative voltage to the ends of the CNT so as to configure the corresponding FET as either an n-type or p-type CNTFET, respectively. Two adjacent CNTFETs, configured such that one is an n-type CNTFET and the other is a p-type CNTFET, can be incorporated into a complementary CNT device. In order to independently adjust threshold voltage of an individual CNTFET, a back gate can also be introduced below the CNT and, particularly, below the channel region of the CNT opposite the front gate. In this manner parasitic capacitances and resistances are minimized.

摘要: A multi-layered gate electrode stack structure of a field effect transistor device is formed on a silicon nano crystal seed layer on the gate dielectric. The small grain size of the silicon nano crystal layer allows for deposition of a uniform and continuous layer of poly-SiGe with a [Ge] of up to at least 70% using in situ rapid thermal chemical vapor deposition (RTCVD). An in-situ purge of the deposition chamber in a oxygen ambient at rapidly reduced temperatures results in a thin SiO2 or SixGeyOz interfacial layer of 3 to 4 A thick. The thin SiO2 or SixGeyOz interfacial layer is sufficiently thin and discontinuous to offer little resistance to gate current flow yet has sufficient [O] to effectively block upward Ge diffusion during heat treatment to thereby allow silicidation of the subsequently deposited layer of cobalt. The gate electrode stack structure is used for both nFETs and pFETs.
