  • Patent number: 7723193
    Abstract: An at least penta-sided-channel type of FinFET transistor may include: a base; a semiconductor body formed on the base, the body being arranged in a long dimension to have source/drain regions sandwiching a channel region, at least the channel, in cross-section transverse to the long dimension, having at least five planar surfaces above the base; a gate insulator on the channel region of the body; and a gate electrode formed on the gate insulator.
    Type: Grant

  • Patent number: 7671420
    Abstract: Disclosed are processes and techniques for fabricating semiconductor substrates for the manufacture of semiconductor devices, particularly CMOS devices, that include selectively formed, high quality single crystal or monocrystalline surface regions exhibiting different crystal orientations. At least one of the surface regions will incorporate at least one faceted epitaxial semiconductor structure having surfaces that exhibit a crystal orientation different than the semiconductor region on which the faceted epitaxial semiconductor structure is formed. According, the crystal orientation in the channel regions of the NMOS and/or PMOS devices may be configured to improve the relative performance of at least one of the devices and allow corresponding redesign of the semiconductor devices fabricated using such a process.

  • Publication number: 20080135879
    Abstract: In a method of fabricating a CMOS transistor, and a CMOS transistor fabricated according to the method, the characteristics of first and second conductivity type MOS transistors are both simultaneously improved. At the same time, the fabrication process is simplified by reducing the number of masks required. The method includes amorphizing the active region of only the second conductivity type MOS transistor, and performing selective etching to form a first recessed region of a first depth in the active region of the first conductivity type MOS transistor and a second recessed region of a second depth that is greater than the first depth in the active region of the second conductivity type MOS transistor.

  • Patent number: 7307274
    Abstract: According to some embodiments of the invention, there is provided line photo masks that includes transistors having reinforcement layer patterns and methods of forming the same. The transistors and the methods provide a way of compensating a partially removed amount of a strained silicon layer during semiconductor fabrication processes. To the end, at least one gate pattern is disposed on an active region of a semiconductor substrate. Reinforcement layer patterns are formed to extend respectively from sidewalls of the gate pattern and disposed on a main surface of the semiconductor substrate. Each reinforcement layer pattern partially exposes each sidewall of the gate pattern. Impurity regions are disposed in the reinforcement layer patterns and the active region of the semiconductor substrate and overlap the gate pattern. Spacer patterns are disposed on the reinforcement layer patterns and partially cover the sidewalls of the gate pattern.
