    摘要： Apparatus suitable for transforming a radiation beam so that it can exit with a predetermined alteration. The apparatus includes a first variably diffractive radiation element for transforming a characteristic of the radiation beam from an original state; a second radiation element juxtaposed to the first radiation element for transforming the same characteristic in a complementary way; and, means for physically deforming the first variably diffractive radiation element so that its diffracting pattern can change in a known way.

    摘要： Techniques for improving on data center best practices are provided. In one aspect, an exemplary methodology for analyzing energy efficiency of a data center having a raised-floor cooling system with at least one air conditioning unit is provided. The method comprises the following steps. An initial assessment is made of the energy efficiency of the data center based on one or more power consumption parameters of the data center. Physical parameter data obtained from one or more positions in the data center are compiled into one or more metrics, if the initial assessment indicates that the data center is energy inefficient. Recommendations are made to increase the energy efficiency of the data center based on one or more of the metrics.

    摘要： A method of detecting the presence of a brush used in a semiconductor wafer cleaner for post-CMP processing is described. Semiconductor wafers are loaded into the wet environment of the wafer cleaner, affixed to a rotatable fixture and rotated at high speed. The rotatable fixture is effectuated by a servo motor linked to a servo controller and a torque monitor. A first torque on the rotating wafer is calculated prior to the start of the brush cleaning cycle. During the brush cleaning cycle, as the brush within the brush cleaner contacts the rotating wafer, the torque on the wafer increases and a second torque is calculated. If, during the brush cleaning cycle, the second torque calculation is substantially equal to the first torque calculation, the brush cleaner is not contacting the wafer and cleaning has not progressed. A tool user can be notified to reaffix the brush within the cleaner. When the second torque calculation is greater than expected, the tool user can be notified that the brush downforce has been improperly set. Inadequate removal of CMP residue is detected before entire wafer lots have passed through an ineffective brush cleaning cycle prior to an inspection point.
