  • Patent number: 10262706
    Abstract: An anti-floating circuit including a first pull-high circuit, a first pull-low circuit and a first control circuit is provided. The first pull-high circuit includes a first P-type transistor and a second P-type transistor and is coupled to a first power terminal. The first pull-low circuit includes a first N-type transistor and a second N-type transistor and is coupled to a second power terminal. A first path is between the first P-type transistor and the first N-type transistor. A second path is between the second P-type transistor and the second N-type transistor. A third path is between the first P-type transistor and the second power terminal. In the first mode, the control circuit turns on the first and second paths and turns off the third path. In the second mode, the control circuit turns off the first and second paths and turns on the third path.

  • Publication number: 20190027811
    Abstract: A mobile device includes a metal back cover, a ground metal element, a feeding radiation element, and a dielectric substrate. The metal back cover has a slot. The feeding radiation element has a feeding point, and includes a first feeding branch, a second feeding branch, and a third feeding branch. The second feeding branch and the first feeding branch extend in opposite directions. The third feeding branch and the first feeding branch extend in the same direction. The feeding radiation element has a vertical projection on the metal back cover, and the vertical projection at least partially overlaps the slot. The dielectric substrate is disposed adjacent to the metal back cover. The ground metal element and the feeding radiation element are disposed on the dielectric substrate. An antenna structure is formed by the feeding radiation element and the slot of the metal back cover.

  • Patent number: 9978634
    Abstract: A method for fabricating a shallow trench isolation includes forming a trench in a substrate, forming a bottom shallow trench isolation dielectric filling a gap of the trench, and forming a top shallow trench isolation dielectric on the bottom shallow trench isolation. The bottom shallow trench isolation dielectric has a concave center portion, and the top shallow trench isolation dielectric is deposited on the bottom shallow trench isolation by a high density plasma chemical vapor deposition process using low deposition to sputter ratio. A semiconductor structure having the shallow trench isolation is also disclosed.
