Publication number: 20140284748Abstract: A light sensor is described that includes a glass substrate having a diffuser formed therein and at least one color filter integrated on-chip (i.e., integrated on the die of the light sensor). In one or more implementations, the light sensor comprises a semiconductor device (e.g., a die) that includes a semiconductor substrate. At least one photodetector (e.g., photodiode, phototransistor, etc.) is formed in the substrate proximate to the surface of the substrate. The color filter is configured to filter light received by the light sensor to pass light in a limited spectrum of wavelengths (e.g., light having wavelengths between a first wavelength and a second wavelength) to the photodetector. A glass substrate is positioned over the substrate and includes a diffuser. The diffuser is configured to diffuse light incident on the diffuser and to pass the diffused light to the at least one color filter for further filtering.Type: ApplicationFiled: June 9, 2014Publication date: September 25, 2014Inventors: Nicole D. Kerness, Arkadii V. Samoilov, Zhihai Wang, Joy T. Jones

Publication number: 20140264711Abstract: Light sensors are described that include a trench structure integrated therein. In an implementation, the light sensor includes a substrate having a dopant material of a first conductivity type and multiple trenches disposed therein. The light sensor also includes a diffusion region formed proximate to the multiple trenches. The diffusion region includes a dopant material of a second conductivity type. A depletion region is created at the interface of the dopant material of the first conductivity type and the dopant material of the second conductivity type. The depletion region is configured to attract charge carriers to the depletion region, at least substantially a majority of the charge carriers generated due to light incident upon the substrate.Type: ApplicationFiled: March 10, 2014Publication date: September 18, 2014Applicant: Maxim Integrated Products, Inc.Inventors: Nicole D. Kerness, Christopher F. Edwards, Khanh Tran, Joy T. Jones, Pirooz Parvarandeh

Publication number: 20140231635Abstract: Optical devices are described that integrate multiple heterogeneous components in a single, compact package. In one or more implementations, the optical devices include a carrier substrate having a surface that includes two or more cavities formed therein. One or more optical component devices are disposed within the respective cavities in a predetermined arrangement. A cover is disposed on the surface of the carrier substrate so that the cover at least substantially encloses the optical component devices within their respective cavities. The cover, which may be glass, is configured to transmit light within the predetermined spectrum of wavelengths.Type: ApplicationFiled: December 27, 2013Publication date: August 21, 2014Applicant: Maxim Integrated Products, Inc.Inventors: Nicole D.

Patent number: 8803068Abstract: Techniques are described to furnish an IR suppression filter, or any other interference based filter, that is formed on a transparent substrate to a light sensor. In one or more implementations, a light sensor includes a substrate having a surface. One or more photodetectors are formed in the substrate. The photodetectors are configured to detect light and provide a signal in response thereto. An IR suppression filter configured to block infrared light from reaching the surface is formed on a transparent substrate. The light sensor may also include a plurality of color pass filters disposed over the surface. The color pass filters are configured to filter visible light to pass light in a limited spectrum of wavelengths to the one or more photodetectors. A buffer layer is disposed over the surface and configured to encapsulate the plurality of color pass filters and adhesion layer.Type: GrantFiled: December 27, 2011Date of Patent: August 12, 2014Assignee: Maxim Integrated Products, Inc.Inventors: Nicole D. Kerness, Arkadii V. Samoilov, Zhihai Wang, Joy T. Jones

Publication number: 20140124797Abstract: Aspects of the disclosure pertain to a system and method for reducing ambient light sensitivity of Infrared (IR) detectors. Optical filter(s) (e.g., absorption filter(s), interference filter(s)) placed over a sensor of the IR detector (e.g., gesture sensor) absorb or reflect visible light, while passing specific IR wavelengths, for promoting the reduced ambient light sensitivity of the IR detector.Type: ApplicationFiled: October 30, 2013Publication date: May 8, 2014Applicant: Maxim Integrated Products, Inc.Inventors: Joy T.
