Abstract: An apparatus to separate a wafer from a pre-sliced boule of wafers may include a conveyor configured to move the pre-sliced boule of wafers from a first end to a second end. A lift yoke, positioned proximate the second end, may include a wafer slot configured to receive a first wafer of the pre-sliced boule therein when the pre-sliced boule is positioned at the second end. A pusher blade may be configured to raise the lift yoke along with the first wafer positioned in its wafer slot from a first position to a second position. The wafer slot may be vertically aligned with the conveyor at the first position and the wafer slot may be positioned above the conveyor in the second position.

Abstract: A cleaning device includes a tank configured to contain a cleaning liquid and one or more substrates in the cleaning liquid. A megasonic transducer array is coupled to the tank and configured to direct megasonic frequency waves to surfaces of the substrates. Multiple pairs of ultrasonic transducers are also coupled to the tank and configured to direct ultrasonic frequency waves to surfaces of the substrates. The megasonic transducer array includes a support plate with a plurality of megasonic transducers and a central plane that extends perpendicular to the support plate. The multiple pairs of ultrasonic transducers are arranged in a mirror symmetric manner on opposite sides of the central plane.

Abstract: Disclosed is a system for controlling the climate within an automobile when the engine thereof is turned off. The system comprises an auxiliary AC compressor disposed in fluid communication with the pre-existing AC lines of the automobile, an engine sensor for detecting the current status of the engine, and an AC switch. The system is configured such that, the compressor is activated upon the switch being turned on and upon the engine being turned off.
