  • Patent number: 7986404
    Abstract: An illumination device and method for inspecting objects having microscopic features is provided. The device includes an illuminator which provides a solid angle of angularly specific illumination defining an illumination angle, selected by a user from among a continuous range of possible illumination angles. The device further includes an object inspector which inspects the object illuminated by the illuminator. The illuminator may include an illumination source, a light concentrator, an illumination angle selector, disposed along a light path between the illumination source and the object inspector. The illumination angle selector may have a first position in which directly-reflected light propagates toward the object plane and a second position in which no light both selected by the illumination angle selector and directly reflected from the object plane enters the collecting lens. Rather, in the second position, only scattered light from the object plane enters the collecting lens.

The illumination module may include a bright field illumination source and/or a dark field illumination source. The telecentric imaging optics includes an upper imaging module having an aperture stop and a lower imaging module positioned between the upper imaging module and object, such that the light source and the aperture stop are located in the back focal plane of the lower imaging module. The lower imaging module images the illumination source into a plane of an aperture stop of the upper imaging module. The optical axis of the upper imaging module is offset with respect to the lower imaging module. The optical axis of the telecentric illumination module is offset with respect to the axis of the lower imaging module in the opposite direction.

  • Patent number: 7619944
    Abstract: Devices allow a system using a memory array, or the memory itself, to more efficiently control refresh intervals. This reduces standby current and the overhead associated with refresh operations. The device includes a variable analog refresh signal generation circuit that initiates a refresh operation on one or more memory cells of a memory array. The circuit integrates a refresh timer element with an event signal generator such that a refresh interval as defined by the refresh timer element is changed when events are detected that may change the data retention time of one or more memory cells. One or more of the circuits is placed to monitor an entire memory array, different sub-arrays, or different portions of different sub-arrays. This allows additional refresh operations to be closely tied to actual events, thus increasing overall efficiency.

  • Patent number: 6661695
    Abstract: A capacitance sensing technique for ferroelectric random access, memory devices and arrays which enables fast sensing operations to be performed allowing for low latency “read” operations and thereby providing overall system performance advantages. Through the use of the technique of the disclosed, concurrent polling and reading of data may be achieved prior to pulsing (or driving) the plate line. This then allows the memory “restore” function to be hidden behind the “read” data stream at the memory device output pins. In accordance with the technique of the present invention, the sensing may begin prior to pulsing the plate line and it is the sensing process itself which interrogates the memory and concurrently prepares the data for the outputs. In this manner, it is the pulsing of the plate line after the data is sensed that performs the “restore” and this operation is not a portion of the “read” access time critical path.
