Publication number: 20140285424Abstract: One embodiment of the user interface system comprises: a volume of fluid; a tactile layer; a retaining wall substantially impermeable to the fluid; a permeable layer; a displacement device; and a touch sensor. The tactile layer, with a back surface, defines a second region, operable between: a retracted state, wherein the second region is substantially flush with a first region; and an expanded state, wherein the second region is substantially proud of the first region. The permeable layer, joined to the back surface of the first region, includes a plurality of fluid ports that communicate a portion of the fluid through the permeable layer to the back surface of the second region. The displacement device directs the fluid through the fluid ports to the back surface to transition the second region from the retracted state to the expanded state. The touch sensor detects a user touch on the tactile layer.Type: ApplicationFiled: March 4, 2014Publication date: September 25, 2014Applicant: Tactus Technology, Inc.Inventors: Micah Yairi, Craig Ciesla, Nathaniel Mark Saal

Patent number: 8253175Abstract: A sealed semiconductor device having reduced delamination of the sealing layer in high temperature, high humidity conditions is disclosed. The semiconductor device includes a substrate and a stack of device layers on the substrate sealed with a sealing layer. The upper surface of a street area of the substrate is oxidized so that the oxidized region extends under the sealing layer. The presence of the oxidized region of the upper surface of the substrate helps reduce the delamination, because the oxidized surface does not react with water to the same extent as a non-oxidized surface. The semiconductor devices remain sealed after dicing through the street area because the oxidized surface does not delaminate.Type: GrantFiled: January 18, 2010Date of Patent: August 28, 2012Inventors: Zhong Pan, Craig Ciesla

Patent number: 7834379Abstract: The invention relates to an avalanche photodiode having enhanced gain uniformity enabled by a tailored diffused p-n junction profile. The tailoring is achieved by a two stage doping process incorporating a solid source diffusion in combination with conventional gas source diffusion. The solid source diffusion material is selected for its solubility to the dopant compared to the solubility of the multiplication layer to dopant. The solid source has a diameter between the first and second diffusion windows. Thus, there are three distinct diffusion regions during the second diffusion. The dopant in the multiplication layer at the edge region, the dopant from the solid source material with a relatively higher dopant concentration (limited by the solubility of the dopant in the solid source material) at the intermediate region, and the central region exposed to an infinite diffusion source from the solid source material as it is continually charged with new dopant from the external gas source.Type: GrantFiled: July 15, 2008Date of Patent: November 16, 2010Assignee: JDS Uniphase CorporationInventors: Zhong Pan, David Venables, Craig Ciesla

Patent number: 7795064Abstract: The present invention provides a front-illuminated avalanche photodiode (APD) with improved intrinsic responsivity, as well as a method of fabricating such a front-illuminated APD. The front-illuminated APD comprises an APD body of semiconductor material, which includes a substrate and a layer stack disposed on a front surface of the substrate. The layer stack includes an absorption layer, a multiplication layer, and a field-control layer. Advantageously, a back surface of the APD body is mechanically and chemically polished, and a reflector having a reflectance of greater than 90% at the absorption wavelength band is disposed on the back surface of the APD body. Thus, incident light that is not absorbed in a first pass through the absorption layer is reflected by the reflector for a second pass through the absorption layer, increasing the intrinsic responsivity of the front-illuminated APD.Type: GrantFiled: October 29, 2008Date of Patent: September 14, 2010Assignee: JDS Uniphase CorporationInventors: Zhong Pan, Craig Ciesla
