    Abstract: A method of forming a semiconductor structure includes providing a substrate including a fin at a surface of the substrate, and forming a fin field-effect transistor (FinFET), which further includes forming a gate stack on the fin; forming a thin spacer on a sidewall of the gate stack; and epitaxially growing a epitaxy region starting from the fin. After the step of epitaxially growing the epitaxy region, a main spacer is formed on an outer edge of the thin spacer. After the step of forming the main spacer, a deep source/drain implantation is performed to form a deep source/drain region for the FinFET.

    Abstract: A frequency jitter generator and a frequency jitter PWM controller are provided for overcoming the shortcoming that a conventional PWM controller reduces the electromagnetic interference issue by means of varying the operating frequency of the PWM controller based on an input voltage, while resulting in the uncertainty of the range of frequency jitter and the difficulty circuit design due to the effect of the input voltage and the load. The frequency jitter generator and PWM controller adjust the range of frequency jitter by using a signal within a fixed voltage range. The invention not only gets rid of the effect of the input voltage and the loading, but also simplifies the circuit design by fixing the range of frequency jitter no greater than a predetermined percentage regardless of the operating frequency of the PWM controller.

    Abstract: A method of forming a FINFET CMOS device structure featuring an N channel device and a P channel device formed in the same SOI layer, has been developed. The method features formation of two parallel SOI fin type structures, followed by gate insulator growth on the sides of the SOI fin type structures, and definition of a conductive gate structure formed traversing the SOI fin type structures while interfacing the gate insulator layer. A doped insulator layer of a first conductivity type is formed on the exposed top surfaces of a first SOI fin type shape, while a second doped insulator layer of a second conductivity type is formed on the exposed top surfaces of the second SOI fin type shape. An anneal procedure results creation of a source/drain region of a first conductivity type in portions of the first SOI fin type shape underlying the first doped insulator layer, and creation of a source/drain region of a second conductivity type in portions of the second SOI fin type shape underlying the second doped insulator layer. Selective deposition of tungsten on exposed top surface of the source/drain regions is then employed to decrease source/drain resistance.

    Abstract: A high-speed PWM control apparatus with adaptive voltage position and a driving signal generating method thereof is provided. The present invention automatically detects a change in the loading and adjusts the voltage position instantaneously for stabilizing the voltage and reducing the loading output power consumption. The present invention does not require a clock signal to generate a driving signal and does not require an error amplifier to control the modulation. Therefore, the present invention has a fast transient response that responds to the change of the loading instantaneously and has a stabilizing effect. When the apparatus is on a continuous conduction mode (CCM), the switching frequency of the controller is still fixed even though the input voltage Vin and the output voltage Vout are changed. The electrical-magnetic noise disturbance is improved.

    Abstract: A method to reduce the inverse narrow width effect in NMOS transistors is described. An oxide liner is deposited in a shallow trench that is formed to isolate active areas in a substrate. A photoresist plug is formed in the shallow trench and is recessed below the top of the substrate to expose the top portion of the oxide liner. An angled indium implant through the oxide liner into the substrate is then performed. The plug is removed and an insulator is deposited to fill the trenches. After planarization and wet etch steps, formation of a gate dielectric layer and a patterned gate layer, the NMOS transistor exhibits an improved Vt roll-off of 40 to 45 mVolts for both long and short channels. The improvement is achieved with no degradation in junction or isolation performance. The indium implant dose and angle may be varied to provide flexibility to the process.
