  • Patent number: 8652971
    Abstract: A MEMS device having a device cavity in a substrate has a cavity etch monitor proximate to the device cavity. An overlying layer including dielectric material is formed over the substrate. A monitor scale is formed in or on the overlying layer. Access holes are etched through the overlying layer and a cavity etch process forms the device cavity and a monitor cavity. The monitor scale is located over a lateral edge of the monitor cavity. The cavity etch monitor includes the monitor scale and monitor cavity, which allows visual measurement of a lateral width of the monitor cavity; the lateral dimensions of the monitor cavity being related to lateral dimensions of the device cavity.

  • Patent number: 8629435
    Abstract: A first test structure includes a first isolation region, a first gate electrode over the first isolation region, a first and a second semiconductor fin, and a first contact plug over the first and the second semiconductor fins. A second test structure includes a second isolation region, a second gate electrode over the second isolation region, a third semiconductor fin and a dielectric fin, and a second contact plug over the third semiconductor fin. The first, the second, and the third semiconductor fins and the dielectric fin have substantially a same fin height. A method includes measuring a first capacitance between the first gate electrode and the first contact plug, measuring a second capacitance between the second gate electrode and the second contact plug, and calculating the same fin height from a capacitance difference between the second capacitance and the first capacitance.

  • Patent number: 8618628
    Abstract: A semiconductor device and a method for manufacturing the same are disclosed. A dummy pattern is formed between a fuse pattern and a semiconductor substrate so as to prevent the semiconductor substrate from being damaged, and a buffer pattern is formed between the dummy pattern and the semiconductor substrate, so that a dummy metal pattern primarily absorbs or reflects laser energy transferred to the semiconductor substrate during the blowing of the fuse pattern, and the buffer pattern secondarily reduces stress generated between the dummy pattern and the semiconductor substrate, resulting in the prevention of a defect such as a crack.

  • Patent number: 8558329
    Abstract: A device includes a substrate having a first surface. A piezoelectric nanowire is disposed on the first surface of the substrate. The piezoelectric nanowire has a first end and an opposite second end. The piezoelectric nanowire is subjected to an amount of strain. A first Schottky contact is in electrical communication with the first end of the piezoelectric nanowire. A second Schottky contact is in electrical communication with the second end of the piezoelectric nanowire. A bias voltage source is configured to impart a bias voltage between the first Schottky contact and the second Schottky contact. A mechanism is configured to measure current flowing through the piezoelectric nanowire. The amount of strain is selected so that a predetermined current will flow through the piezoelectric nanowire when light of a selected intensity is applied to a first location on the piezoelectric nanowire.
