Patent number: 6753922Abstract: An imaging system includes an image sensor that is attached to a circuit board via a mass reflow process. The image sensor captures image data and provides the image data at an output of the imaging system. In one embodiment, the image sensor uses a color filter array (CFA) material that is substantially stable through the mass reflow process.Type: GrantFiled: October 13, 1998Date of Patent: June 22, 2004Assignee: Intel CorporationInventors: Kabul S. Sengupta, Azar Assadi, Alan B. Alley, Robert C. Sundahl

Patent number: 6665014Abstract: An array of photosensitive devices may be formed with improved fill factors by including a diffractive microlens which may have a stepped configuration. The microlens may be formed of a sol-gel material having a photoinitiator, or other materials that may be defined with low temperature techniques commonly used in connection with photoresist. In particular, a gray scale mask may be used to define a plurality of steps in the resulting microlens which have different diffractive characteristics.Type: GrantFiled: November 25, 1998Date of Patent: December 16, 2003Assignee: Intel CorporationInventors: Azar Assadi, Kannan Raj

Patent number: 6611036Abstract: A photosensitive device with a microlens array may be packaged for surface mount packaging and subsequent mass reflow processing without significantly degrading the optical performance of the microlens. The microlens may be formed using a series of heat steps of increasing time and temperature. In addition, the microlens may be bleached to prevent degradation of its optical transmissivity at temperatures normally associated with surface mount techniques.Type: GrantFiled: July 31, 2001Date of Patent: August 26, 2003Assignee: Intel CorporationInventors: Azar Assadi, Parvin Mossahebi, Kabul Sengupta

Patent number: 6166369Abstract: A microcollector for photosensitive devices such as imaging arrays for digital cameras, scanners and other devices, may be formed on a semiconductor structure adjacent to a photosensitive element. The collector may include reflective surfaces arranged about the photosensitive element so as to reflect incident light towards the photosensitive element. The collector may be used in conjunction with a refractive/diffractive microlens to further focus light onto the photosensitive element. As a result, the fill factor of the photosensitive device may be improved, and the signal to noise ratio may also be enhanced.Type: GrantFiled: November 25, 1998Date of Patent: December 26, 2000Assignee: Intel CorporationInventors: Azar Assadi, Kannan Raj
