  • Publication number: 20240088297
    Abstract: In a method of manufacturing a semiconductor device including a Fin FET, a fin structure extending in a first direction is formed over a substrate. An isolation insulating layer is formed over the substrate so that an upper portion of the fin structure is exposed from the isolation insulating layer. A gate structure extending in a second direction crossing the first direction is formed over a part of the fin structure. A fin mask layer is formed on sidewalls of a source/drain region of the fin structure. The source/drain region of the fin structure is recessed. An epitaxial source/drain structure is formed over the recessed fin structure. In the recessing the source/drain region of the fin structure, a plasma process combining etching and deposition processes is used to form a recess having a rounded corner shape in a cross section along the second direction.

  • Publication number: 20240072667
    Abstract: A switching regulator includes a boost power stage circuit and a control circuit. The boost power stage circuit includes: at least one power switch configured to switch a terminal of an inductor according to an operation signal during a normal operation period, such that the terminal of the inductor is switched between an output voltage and ground level; and a power line switch connected in series to the inductor between the input voltage and the output voltage. The power line switch is turned OFF when the output voltage is short to ground level, to prevent a short current from flowing from input voltage to ground level. The control circuit generates the operation signal according to the output voltage and determines whether the power line switch is P-type or N-type MOS device, so as to turn OFF the power line switch when the output voltage is short to ground level.

  • Patent number: 9991385
    Abstract: The present disclosure relates to a semiconductor device that controls a strain on a channel region by forming a dielectric material in recesses, adjacent to a channel region, in order to provide control over a volume and shape of a strain inducing material of epitaxial source/drain regions formed within the recesses. In some embodiments, the semiconductor device has epitaxial source/drain regions arranged in recesses within an upper surface of a semiconductor body on opposing sides of a channel region. A gate structure is arranged over the channel region, and a dielectric material is arranged laterally between the epitaxial source/drain regions and the channel region. The dielectric material consumes some volume of the recesses, thereby reducing a volume of strain inducing material in epitaxial source/drain regions formed in the recesses.

  • Patent number: 9564528
    Abstract: A method for manufacturing a semiconductor device includes forming a fin structure over a substrate. An isolation insulating layer is formed so that an upper part of the fin structure protrudes from the isolation insulating layer. A gate structure is formed over a part of the fin structure. Recesses are formed in the isolation insulating layer at both sides of the fin structure. A recess is formed in a portion of the fin structure which is not covered by the gate structure. The recess in the fin structure and the recesses in the isolation insulating layer are formed such that a depth D1 of the recess in the fin structure and a depth D2 of the recesses in the isolation insulating layer measured from an uppermost surface of the isolation insulating layer satisfy 0?D1?D2 (but D1 and D2 are not zero at the same time).
