摘要： This disclosure describes a clear overmolding cap for protecting the photonic devices in optoelectronic packages from damage due to handling, module assembly, board assembly, and environmental exposure in field applications. The overmolding of the devices with a clear mold cap or similar material also provides a standoff for optical fibers positioned next to the active facets. The photonic devices are attached to a substrate, which may be flexible that has electronic traces that allow the photonic devices to be connected to an external device such as a semiconductor device. A technique for manufacturing the overmolding cap using a mold die system in combination with a rigid carrier is also disclosed. The rigid carrier is used to maintain the shape of the substrate during the molding process. The proposed method applies to photonic devices used in optoelectronic packages that can serve as transceivers, transmitters, or receivers.

摘要： The present invention provides a low cost device that has a true die to external fiber optic connection. Specifically, the present invention relates to an optical device package joined to a semiconductor device package. In some cases, the combination is joined using wirebond studs and an adhesive material. In other cases, the combination is joined using an anisotropic conductive film. Yet, in other cases, the combination is joined using solder material. Each of these joining mechanisms provides high levels of thermal, electrical and optical performance. The joining mechanisms can apply to optical sub-assembly and chip sub-assembly interfaces in transceivers, transmitters, as well as receivers for opto-electronic packages.

摘要： A stacked molded package comprising a semiconductor package attached to an electronic device. The semiconductor package includes a semiconductor die which is connected to a set of wire leads and is encapsulated within a protective molding material. Additionally, solder bumps within the molding material are attached to input and output contact points on the semiconductor die. Portions of the solder bumps are exposed through the surface of the molding material so that contact can be made with the electrical contacts of an electronic device to be stacked upon the semiconductor package. The electronic device may be, for example, another semiconductor die or an opto-electronic transceiver. The present invention also includes a method for manufacturing the stacked molded package. The method involves forming the semiconductor package within a molding chamber which is injected with the protective molding material. The method further involves lowering the top surface of the molding chamber onto the solder bumps of the semiconductor package. The contact between the top surface of the molding chamber and the solder bumps flattens a portion of the solder bumps and prevents the flattened portion from being covered with molding material. Manufacturing the semiconductor package may be performed with the current manufacturing infrastructure which is used to make semiconductor packages according to specific form factors. A stacked package is formed when an electronic device is attached to the molded package.

摘要： A method and system is presented for bypassing a local Domain Name Server (DNS) when using edge caching servers. Domain names of frequently used business applications that are known to rely upon edge servers, together with the corresponding authoritative DNSs, are listed in both local hosts file and user defined FSFD local configuration file fsfd.conf. When the client computer's browser attempts to resolve a domain name, a File System Filtering Driver (FSFD) in the client computer intercepts the browser's request. If the domain name which is being resolved is found in a local FSFD configuration file fsfd.conf, then the FSFD initiates a DNS request directly to the appropriate authoritative DNS whose IP address gets extracted from the fsfd.conf record, thus bypassing the local DNS. The authoritative DNS returns the IP address for an edge caching server that is topographically proximate to the client computer's browser.
摘要翻译：提出了一种方法和系统，用于在使用边缘缓存服务器时绕过本地域名服务器（DNS）。在本地主机文件和用户定义的FSFD本地配置文件fsfd.conf中列出了已知依赖于边缘服务器的经常使用的业务应用程序的域名以及相应的权威DNS。当客户端计算机的浏览器尝试解析域名时，客户端计算机中的文件系统过滤驱动程序（FSFD）会拦截浏览器的请求。如果正在解析的域名在本地FSFD配置文件fsfd.conf中找到，则FSFD将直接向适当的授权DNS发起DNS请求，该域名的IP地址从fsfd.conf记录中提取出来，从而绕过本地DNS 。权威性DNS返回位于邻近客户端计算机浏览器的边缘缓存服务器的IP地址。
