  • Patent number: 9490363
    Abstract: The present invention discloses a tunneling field effect transistor having a three-side source and a fabrication method thereof, referring to field effect transistor logic devices and circuits in CMOS ultra large scale integrated circuits (ULSI). By means of the strong depletion effect of the three-side source, the transistor can equivalently achieve a steep doping concentration gradient for the source junction, significantly optimizing the sub-threshold slope of the TFET. Meanwhile, the turn-on current of the transistor is boosted. Furthermore, due to a region uncovered by the gate between the gate and the drain, the bipolar conduction effect of the transistor is effectively inhibited, and on the other hand, in the small-size transistor a parasitic tunneling current at the corner of the source junction is inhibited. The fabrication method is simple and can be accurately controlled.

    Abstract: Provided are a method for suppressing a leakage current of a tunnel field-effect transistor (TFET), a corresponding device, and a manufacturing method, related to the field of field-effect transistor logic devices and circuits in CMOS ultra large-scale integration (ULSI). By inserting an insulating layer (7) between a source region (10) and a transistor body below a tunneling junction, and by inserting no insulating layer at a tunneling junction between a source region and a channel, a source/drain direct tunneling leakage current in a small-sized TFET device is effectively suppressed, and a threshold slope is effectively improved. The manufacturing method for the corresponding device is completely compatible with an existing CMOS process.

  • Publication number: 20160079400
    Abstract: The present invention discloses a junction-modulated tunneling field effect transistor and a fabrication method thereof, belonging to a field of field effect transistor logic device and the circuit in connection with CMOS ultra large scale integrated circuit (ULSI). The PN junction provided by a highly-doped source region surrounding three sides of the vertical channel region of the tunneling field effect transistor can deplete effectively the channel region, so that the energy band of the surface channel under the gate is lifted, therefore the device may obtain a steeper energy band and a narrower tunneling barrier width than the conventional TFET when the band-to-band tunneling occurs, equivalently achieving the effect of a steep doping concentration gradient at the source tunneling junction, and thereby the sub-threshold characteristics are significantly improved while the turn-on current of the device is improved relative to the conventional TFET.
