  • Publication number: 20210265219
    Abstract: Processes to form differently-pitched gate structures are provided. An example method includes providing a workpiece having a substrate and semiconductor fins spaced apart from one another by an isolation feature, depositing a gate material layer over the workpiece, forming a patterned hard mask over the gate material layer, the patterned hard mask including differently-pitched elongated features, performing a first etch process using the patterned hard mask as an etch mask through the gate material layer to form a trench, performing a second etch process using the patterned hard mask as an etch mask to extend the trench to a top surface of the isolation feature, and performing a third etch process using the patterned hard mask to extend the trench into the isolation feature. The first etch process includes use of carbon tetrafluoride and is free of use of oxygen gas.

  • Publication number: 20210257359
    Abstract: A device includes a plurality of fin structures that each protrude vertically upwards out of a substrate and each extend in a first direction in a top view. A gate structure is disposed over the fin structures. The gate structure extends in a second direction in the top view. The second direction is different from the first direction. The fin structures have a fin pitch equal to a sum of: a dimension of one of the fin structures in the second direction and a distance between an adjacent pair of the fin structures in the second direction. An end segment of the gate structure extends beyond an edge of a closest one of the fin structures in the second direction. The end segment has a tapered profile in the top view or is at least 4 times as long as the fin pitch in the second direction.

  • Publication number: 20210257310
    Abstract: An alignment structure for a semiconductor device and a method of forming same are provided. A method includes forming an isolation region over a substrate and forming an alignment structure over the isolation region. Forming the alignment structure includes forming a sacrificial gate electrode layer over the substrate and the isolation region. The sacrificial gate electrode layer is patterned to form a plurality of first sacrificial gates over the isolation region. At least one of the plurality of first sacrificial gates is reshaped. The at least one of the plurality of first sacrificial gates is disposed at an edge of the alignment structure in a plan view. A sidewall of the at least one of the plurality of first sacrificial gates comprises a notch at an interface between the at least one of the plurality of first sacrificial gates and the isolation region.

  • Publication number: 20160097643
    Abstract: A mobile navigation system includes positioning devices and a positioning datasheet generating unit. The positioning devices are installed in multiple areas and transmit wireless signals containing positioning device serial numbers. The positioning datasheet generating unit provides an electronic region map and a positioning datasheet to a mobile device. The positioning datasheet includes location information of the areas, the associated positioning device serial numbers, and navigation routes between any two of the areas. The mobile device searches the positioning datasheet to obtain the location information of a current area of itself with the positioning device serial number in the wireless signal received from the positioning device. The mobile device displays the current area on the electronic region map. Upon receiving a destination area, the mobile device searches the positioning datasheet to find a navigation route between the current area and the destination area and displays the navigation route.
