  • Publication number: 20100164040
    Abstract: A microlens structure and a method of fabrication thereof are provided. The method comprises forming a layer of microlens material over a substrate, which has photo-sensitive elements formed therein. The microlens material, which comprises a photo-resist material, is exposed in accordance with a desired pattern a plurality of times. The energy used with each exposure process is less than the energy required if a single exposure is used. Furthermore, the masks used for each exposure may differ. In an embodiment, the masks are varied so as to create a notch in the upper corner of the microlens. The microlens structure may have a height less than about 0.5 um and/or a gap between microlenses less than about 0.2 um. In an embodiment, one or more dielectric layers having a combined thickness greater than about 3.5 um are interposed between the photo-sensitive elements and the microlenses.

  • Patent number: 7505206
    Abstract: A method of manufacturing a microlens device by depositing a microlens material layer over a substrate that includes photo-sensors. The microlens material layer is then exposed and developed to define microlens material elements, including first microlens material elements and second microlens material elements. Each second microlens material element is substantially greater in thickness relative to each first microlens material element. The microlens material elements are then heated to form a microlens array that includes first microlens array elements, each corresponding to a first microlens material element, and second microlens array elements, each corresponding to a second microlens material element. Each first microlens array element has a substantially greater focal length relative to each second microlens array element. For example, each second microlens array element is substantially greater in thickness relative to each first microlens array element.

  • Publication number: 20040107244
    Abstract: A scalable and intelligent network platform for distributed system has at least one application server and multiple connected endpoint machines, which is capable of supporting commonly used data formats and message exchange protocols. This network platform enables endpoint machines running on different operating systems and using different message exchange protocols to perform downloading or access network drives. The network platform also allows remote clients in different domain to log onto the application server cross platform to obtain a copy of the frequently used program software for downloading. The present invention provides a management model for computer resources in the Intranet environment with a highly flexible architecture.
