Abstract:
A method for initializing a first operation in a first module (120) at a first start time value in a first time base, the method comprising generating a clock signal (402, 116), generating a second time base (403) in the first module (120) based on the clock signal (116), determining a second sync value (405) in the second time base, determining a first sync value (406) in the first time base corresponding to a second sync value in the second time base, determining a start trigger value (410) in the second time base based on the first sync value and the start time value in the first time base, and initializing the first operation (411) in the first module (120) based on the start trigger value and a current value of the second time base in the first module.
Abstract:
A high surface area coil for use with a physical vapor deposition apparatus comprising a first surface. At least a portion of the first surface has a macrotexture with a surface roughness between about 15 µm and about 150 µm. At least a portion of the first surface has a microtexture with a surface roughness between about 2 µm and 15 µm.
Abstract:
The present invention has its objective to reduce the size of an electron beam sterilization system so as to lower the cost and complexity of the overall system. An electron beam emitter according to the present invention includes a power supply (11), a cathode (12) connected to the power supply (11), an electron lens (13) that surrounds the cathode (12) and has a plurality of apertures (13a), a flange (14) having a plurality of nozzles (14a), and a chamber (15) that keeps a vacuum, with the flange (14), around the electron lens (13) and the cathode (12). The cathode (12) is partially provided on a straight line passing through the aperture (13a) and the nozzle (14a).
Abstract:
A CRT gun is used to inspect substrates in a voltage contrast system. The CRT gun directs a beam of electrons at the substrate, which is at least partially disposed in a vacuum chamber. The vacuum chamber is evacuated and provided with an electron detector to sense secondary electron emission due to impingement of the electron stream on the substrate. In an alternative embodiment, a plurality of CRT guns are used in conjunction with a common vacuum chamber. The plural CRTs may share a common electron detector, or may each be provided with an associated electrostatically isolated detector. The system is preferably used to detect flat panel displays (FPDs) during manufacture.
