  • Publication number: 20180328985
    Abstract: An apparatus and method for optical probing of a DUT is disclosed. The system enables identifying, localizing and classifying faulty devices within the DUT. A selected area of the DUT is imaged while the DUT is receiving test signals, which may be static or dynamic, i.e., causing certain of the active devices to modulate. Light from the DUT is collected and is passed through a rotatable diffracting element prior to imaging it by a sensor and converting it into an electrical signal. The resulting image changes depending on the rotational positioning of the grating. The diffracted image is inspected to identify, localize and classify faulty devices within the DUT.

  • Publication number: 20180286749
    Abstract: A first metallization layer comprising a set of first conductive lines that extend along a first direction on a first insulating layer on a substrate. A second insulating layer is on the first insulating layer. A second metallization layer comprises a set of second conductive lines on a third insulating layer and on the second insulating layer above the first metallization layer. The set of second conductive lines extend along a second direction that crosses the first direction at an angle. A via between the first metallization layer and the second metallization layer. The via is self-aligned along the second direction to one of the first conductive lines.

  • Patent number: 8089051
    Abstract: One embodiment relates to a method of controllably reflecting electrons from an array of electron reflectors. An incident electron beam is formed from an electron source, and the incident beam is directed to the array of electron reflectors. A first plurality of the reflectors is configured to reflect electrons in a first reflective mode such that the reflected electrons exiting the reflector form a focused beam. A second plurality of the reflectors is configured to reflect electrons in a second reflective mode such that the reflected electrons exiting the reflector are defocused. Another embodiment relates to an apparatus of a dynamic pattern generator for reflection electron beam lithography. Other embodiments, aspects and features are also disclosed.
