Patent number: 8274046Abstract: This invention provides a monochromator for reducing energy spread of a primary charged particle beam in charged particle apparatus, which comprises a beam adjustment element, two Wien-filter type dispersion units and an energy-limit aperture. In the monochromator, a double symmetry in deflection dispersion and fundamental trajectory along a straight optical axis is formed, which not only fundamentally avoids incurring off-axis aberrations that actually cannot be compensated but also ensures the exit beam have a virtual crossover which is stigmatic, dispersion-free and inside the monochromator. Therefore, using the monochromator in SEM can reduce chromatic aberrations without additionally incurring adverse impacts, so as to improve the ultimate imaging resolution. The improvement of the ultimate imaging resolution will be more distinct for Low-Voltage SEM and the related apparatuses which are based on LVSEM principle, such as the defect inspection and defect review in semiconductor yield management.Type: GrantFiled: May 19, 2011Date of Patent: September 25, 2012Assignee: Hermes Microvision Inc.Inventors: Weiming Ren, Zhongwei Chen

Patent number: 8256431Abstract: A method for treating presbyopia utilizes an Erbium based, pulsed laser to sever sub-conjunctival strictures located within the scleral matrix of the eye. Introduction of treatment energy into the scleral matrix increases or facilitates an increase in accommodation, thereby mitigating the effects of presbyopia. The treatment energy can be directed into the scleral matrix to form tunnel ablations in and through the strictures of the scleral matrix. The tunnel ablations can enhance the accommodation of the patient's eye, enabling the eye to refocus at near distances while not losing its ability to focus at a distance.Type: GrantFiled: October 30, 2007Date of Patent: September 4, 2012Assignee: BIOLASE, Inc.Inventor: Marcia Angela Van Valen
