Publication number: 20120170102Abstract: We describe a phase modulating spatial light modulator (SLM). The SLM comprises a substrate bearing multiple SLM pixels, each of the SLM pixels comprising a MEMS (micro electromechanical system) optical phase modulating structure. The MEMS optical phase modulating structure comprises: a pixel electrode; a spring support structure around a perimeter of the pixel electrode; and a mirror spring supported by the spring support structure. The mirror spring comprises a mirror support and a plurality of mirror spring arms each extending between the mirror support and the spring support structure, and a mirror mounted on the mirror support. Each mirror spring arm has a spiral or serpentine shape. A voltage applied to the pixel electrode flexes the mirror spring and causes the mirror to translate perpendicularly to the substrate substantially without tilting.Type: ApplicationFiled: December 31, 2010Publication date: July 5, 2012Inventors: Justin Payne, Howard Woo, Vlad Novotny, Adrian James Cable

Patent number: 8207010Abstract: It is an object to form a high-quality crystalline semiconductor layer directly over a large-sized substrate with high productivity without reducing the deposition rate and to provide a photoelectric conversion device in which the crystalline semiconductor layer is used as a photoelectric conversion layer. A photoelectric conversion layer formed of a semi-amorphous semiconductor is formed over a substrate as follows: a reaction gas is introduced into a treatment chamber where the substrate is placed; and a microwave is introduced into the treatment chamber through a slit provided for a waveguide that is disposed in approximately parallel to and opposed to the substrate, thereby generating plasma. By forming a photoelectric conversion layer using such a semi-amorphous semiconductor, a rate of deterioration in characteristics by light deterioration is decreased from one-fifth to one-tenth, and thus a photoelectric conversion device that has almost no problems for practical use can be obtained.Type: GrantFiled: May 23, 2008Date of Patent: June 26, 2012Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Yasuyuki Arai
