Publication number: 20170294291Abstract: An electron-beam induced plasma is utilized to establish a non-mechanical, electrical contact to a device of interest. This plasma source may be referred to as atmospheric plasma source and may be configured to provide a plasma column of very fine diameter and controllable characteristics. The plasma column traverses the atmospheric space between the plasma source into the atmosphere and the device of interest and acts as an electrical path to the device of interest in such a way that a characteristic electrical signal can be collected from the device. Additionally, by controlling the gases flowing into the plasma column the probe may be used for surface modification, etching and deposition.Type: ApplicationFiled: September 17, 2015Publication date: October 12, 2017Inventors: Nedal SALEH, Unit B STERLING, Daniel TOET, Arie GLAZER, Ronen LOEWINGER, Sriram KRISHNASWAMI

Publication number: 20090255911Abstract: Laser scribing can be performed on a workpiece (104) such as substrates with layers formed thereon for use in a solar panel without need to rotate the workpiece (104) during the scribing process. A series of lasers (602, 622) can be used to concurrently remove material from multiple positions on the workpiece (104). Each laser (602, 622) can have at least one scanning device (614, 630, 632) positioned along a beam path thereof in order to adjust a position of the laser output relative to the workpiece (104). By adjusting the beam or pulse positions using the scanning devices (614, 630, 632) while translating the workpiece (104), substantially any pattern can be scribed into at least one layer of the workpiece (104) without the need for any rotation of the workpiece (104).Type: ApplicationFiled: April 10, 2009Publication date: October 15, 2009Applicant: Applied Materials, Inc.Inventors: Sriram Krishnaswami, Shinichi Kurita, Bassam Shamoun, Benjamin M.
