  • Publication number: 20080096342
    Abstract: The present invention relates to complementary metal-oxide-semiconductor (CMOS) circuits, as well as methods for forming such CMOS circuits. More specifically, the present invention relates to CMOS circuits that contain passive elements, such as buried resistors, capacitors, diodes, inductors, attenuators, power dividers, and antennas, etc., which are characterized by an end contact resistance of less than 90 ohm-microns. Such a low end resistance can be achieved either by reducing the spacer widths of the passive elements to a range of from about 10 nm to about 30 nm, or by masking the passive elements during a pre-amorphization implantation step, so that the passive elements are essentially free of pre-amorphization implants.

  • Publication number: 20070254438
    Abstract: A method for forming a transistor. A semiconductor substrate is provided. The semiconductor substrate is patterned to provide a first body edge. A first gate structure of a first fermi level is provided adjacent the first body edge. The semiconductor substrate is patterned to provide a second body edge. The first and second body edges of the semiconductor substrate define a transistor body. A second gate structure of a second fermi level is provided adjacent the second body edge. A substantially uniform dopant concentration density is formed throughout the transistor body.

  • Publication number: 20060239057
    Abstract: A D-Cache SRAM cell having a modified design in schematic and layout that exhibits increased symmetry from the circuit schematic and the physical cell layout perspectives. That is, the SRAM cell includes two read ports and minimizes asymmetry by provisioning one read port on a true side and one on the complement side. Asymmetry is additionally minimized in layout as cross coupling on both the true and complement sides rises up one level by providing from the local interconnect level a via connection to a M1 or metallization level. Moreover, the distance between the local interconnect (MC) and the gate conductor structure (PC) has been enlarged and equalized for each of the pFETs in the cross-latched SRAM cell. As a result, the SRAM cell has been rendered insensitive to overlay (local interconnect processing too close) by maximizing this MC-PC distance.

  • Publication number: 20050287798
    Abstract: Methods for preventing cavitation in high aspect ratio dielectric regions in a semiconductor device, and the device so formed, are disclosed. The invention includes depositing a first dielectric in the high aspect ratio dielectric region between a pair of structures, and then removing the first dielectric to form a bearing surface adjacent each structure. The bearing surface prevents cavitation of the interlayer dielectric that subsequently fills the high aspect ratio region.

  • Publication number: 20050221543
    Abstract: Accordingly, the present invention provides a double gated transistor and a method for forming the same that results in improved device performance and density. The preferred embodiment of the present invention uses provides a double gated transistor with asymmetric gate doping, where one of the double gates is doped degenerately n-type and the other degenerately p-type. By doping on of the gates n-type, and the other p-type, the threshold voltage of the resulting device is improved. In particular, by asymmetrically doping the two gates, the resulting transistor can, with adequate doping of the body, have a threshold voltage in a range that enables low-voltage CMOS operation. For example, a transistor can be created that has a threshold voltage between 0V and 0.5V for nFETs and between 0 and ?0.5V for pFETs.

  • Publication number: 20050121676
    Abstract: The present invention provides a device design and method for forming the same that results in Fin Field Effect Transistors having different gains without negatively impacting device density. The present invention forms relatively low gain FinFET transistors in a low carrier mobility plane and relatively high gain FinFET transistors in a high carrier mobility plane. Thus formed, the FinFETs formed in the high mobility plane have a relatively higher gain than the FinFETs formed in the low mobility plane. The embodiments are of particular application to the design and fabrication of a Static Random Access Memory (SRAM) cell. In this application, the bodies of the n-type FinFETs used as transfer devices are formed along the {110} plane. The bodies of the n-type FinFETs and p-type FinFETs used as the storage latch are formed along the {100}.
