Abstract: A semiconductor device and method of manufacturing the same are provided. The semiconductor device includes a substrate and a gate structure disposed on the substrate. The semiconductor device also includes a source region and a drain region disposed within the substrate. The substrate includes a drift region laterally extending between the source region and the drain region. The semiconductor device further includes a first stressor layer disposed over the drift region of the substrate. The first stressor layer is configured to apply a first stress to the drift region of the substrate. In addition, the semiconductor device includes a second stressor layer disposed on the first stressor layer. The second stressor layer is configured to apply a second stress to the drift region of the substrate, and the first stress is opposite to the second stress.

Abstract: An electronic device (100) includes a metal shell (1) having a number of walls (11,12) and an antenna unit (3). The metal wall has an interior space (17) defined therebetween, at least one recess (110) defined on one of the wall (11), and a mating member (111) disposed around the recess and extending into the interior space. The antenna unit is received in the recess and has a locating portion (36) extending from a side portion thereof and pivotably engaging with the mating member. When the antenna unit is rotated from a closed position to an opening position, another side portion of the antenna unit extends outward from the recess.

Abstract: A hinge device comprises a male hinge member and a female hinge member. The male hinge member includes a pivoting rod at an end thereof, and a first mounting plate at an opposite end thereof, the first mounting plate being used for fixing the male hinge member onto a display unit of a portable computer. The female hinge member includes a body and a second mounting plate for fixing the female hinge member onto a mainframe unit of the portable computer. A first contacting section is defined on an outer periphery of the pivoting rod of the male hinge member. A second contacting section is defined on an inner periphery of the body for contacting with the first contacting section. A pair of grooves are defined in the second contacting section for retaining lubrication grease.
