    Abstract: A method of fabricating a complementary metal oxide semiconductor (CMOS) device, wherein the method comprises forming a first well region (103) in a semiconductor substrate (102) for accommodation of a first type semiconductor device (130); forming a second well region (104) in the semiconductor substrate (102) for accommodation of a second type semiconductor device (140); shielding the first type semiconductor device (130) with a mask (114); depositing a first metal layer (118) over the second type semiconductor device (140); performing a first salicide formation on the second type semiconductor device (140); removing the mask (114); depositing a second metal layer (123) over the first and second type semiconductor devices (130,140); and performing a second salicide formation on the first type semiconductor device (130). The method requires only one pattern level and it eliminates pattern overlay as it also simplifies the processes to form different suicide material over different devices.

    Abstract: PROBLEM TO BE SOLVED: To provide a device structure of SOI(silicon on isulator) CMOS (complementary metal oxide semiconductor) in which avalanche multiplication of current flowing through a device is increased when an FET(field effect transistor) is turned on and body charges are removed when the FET is turned off. SOLUTION: An FET having an electric floating body is substantially isolated electrically from a substrate. A high resistance path 16 for coupling the floating body is provided at the source. The resistor is operated as a floating body for active switching and a body grounded in waiting mode in order to reduce leakage current. The high resistance path has a resistance of at least 1 MΩ and made of polysilicon. The resistor is formed using a split polysilicon process for opening a hole in a first polysilicon layer in order that an embedded contact mask 19 brings a second polysilicon layer into contact with the substrate.

    Abstract: Protuberances (5), having vertical (h) and lateral (p) dimensions less than the wavelength range of lights detectable by a photodiode (8), are formed at an optical interface between two layers having different refractive indices. The protuberances may be formed by employing self-assembling block copolymers that form an array of sub lithographic features of a first polymeric block component (112) within a matrix of a second polymeric block component (111). The pattern of the polymeric block component is transferred into a first optical layer (4) to form an array of nanoscale protuberances. Alternately, conventional lithography may be employed to form protuberances having dimensions less than the wavelength of light. A second optical layer is formed directly on the protuberances of the first optical layer. The interface between the first and second optical layers has a graded refractive index, and provides high transmission of light with little reflection.

    Abstract: Disclosed is semiconductor structure (100) with an insulator layer (120) on a semiconductor substrate (110) and a device layer (130) is on the insulator layer. The substrate (110) is doped with a relatively low dose of a dopant (111) having a given conductivity type such that it has a relatively high resistivity. Additionally, a portion (102) of the semiconductor substrate immediately adjacent to the insulator layer can be doped with a slightly higher dose of the same dopant (111), a different dopant (112) having the same conductivity type or a combination thereof (111 and 112). Optionally, micro-cavities (122, 123) are created within this same portion (102) so as to balance out any increase in conductivity with a corresponding increase in resistivity. Increasing the dopant concentration at the semiconductor substrate-insulator layer interface raises the threshold voltage (Vt) of any resulting parasitic capacitors and, thereby reduces harmonic behavior. Also disclosed herein are embodiments of a method and a design structure for such a semiconductor structure.

    Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor structure including a thin gate dielectric in which nitrogen is selectively enriched.
    SOLUTION: Although an introducing amount of nitrogen is sufficient to cause gate leakage and the infiltration of a dopant to be reduced, or to prevent these, the amount does not decrease device performance much. Nitrogen lower than that of a gate dielectric of nFET in density is introduced into a gate dielectric of a pFET. Nitriding can be selectively carried out by rapid thermal nitridation (RTN), furnace nitriding, remote plasma nitriding (RPN), decoupled plasma nitriding (DPN), and wale implantation or polysilicon implantation, or by various techniques, including combinations of these methods.
