Abstract: A method is proposed that allows a static design of an optical pickup unit (OPU) that delivers two output beams (30, 32). Both laser beams (30, 32) result in successive spots, which have the appropriate characteristics. In this OPU concept both read and write spots are present at the same time, and they are sufficiently spaced apart in the focus direction. This allows switching from the read situation to the write situation by introducing an appropriate focus offset in the electronics. The two output beams (30,32) are generated from a polarized incoming beam, said polarized incoming beam is split by a tilted birefringent grating (18). ® KIPO & WIPO 2007

Title: In-situ monitoring on a spinning-disk ion implanter
Inventor: PEREL ALEXANDER
IPC: H01L21/66
Filed: 2005-03-18
Abstract: The present invention is directed to in- situ detection of particles and other such features in an ion implantation system during implantation operations to avoid such additional monitoring tool steps otherwise expended before and/or after implantation, for example. One or more such systems are revealed for detecting scattered light from particles on one or more semiconductor wafers illuminated by a light source (e.g., laser beam). The system comprises an ion implanter having a laser for illumination of a spot on the wafer and a pair of detectors (e.g., PMT or photodiode) rotationally opposite from the ion implantation operations. A wafer transport holds a wafer or wafers for translational scanning under the fixed laser spot. A computer analyzes the intensity of the scattered light detected from the illuminated wafer (workpiece), and may also map the light detected to a unique position. For example, particles or other such contaminates may be identified on wafers during the implantation process before additional time and resources are consumed, and aid in determining the sources of such contaminates. Further, threshold analysis of the quantity or size of such particles, for example, may provide a system interlock for shutdown or feedback control.
