摘要： A drop-in aperture 20, which improves the performance and lowers the cost of electro-optical SLM packages. The disclosed package provides a separate metal light shield (aperture) 20 and antireflective coated cover 33, and positions the aperture 20 inside the package 40 in close proximity to the SLM's 41 surface. This approach further uses an on-chip SLM light shield to define the projected screen border, thereby making the edge definition of the metal drop-in aperture less critical. Therefore, the cover can be mounted well away from the plane of the SLM, which relaxes the defect requirements of the cover and lowers the cost of the overall package. The package of this invention improves the performance and lifetime and lowers the cost of projection display systems.
摘要翻译：插入孔20，其提高了性能并降低了电光SLM封装的成本。所公开的封装提供单独的金属光屏蔽（孔）20和防反射涂层盖33，并且将孔20定位在封装40内靠近SLM的41表面。该方法还使用片上SLM光罩来定义投影屏幕边界，从而使得金属入射孔的边缘定义不太关键。因此，盖可以远离SLM的平面安装，这放宽了盖的缺陷要求并降低了整体封装的成本。本发明的封装提高了性能和使用寿命并降低了投影显示系统的成本。

摘要： An improved method for fabricating a window frame/window piece assembly is disclosed in this application. A window frame having an opening in its inner portion is provided. According to one aspect, the window frame can be formed from a unitary piece of sheet metal. A transparent piece is attached to the inner portion of the window frame through a molding process. According to one embodiment, the window frame is placed within a mold such that the inner portion of the window frame projects into an inner cavity inside the mold. After the mold has been closed, a transparent material is injected into the inner cavity so that it bonds with the inner portion of the window frame. After the bond of between the transparent material and the window frame is set, the window frame/window piece assembly is removed from the mold. According to another embodiment, a plurality of window frames may be loaded into a single mold so that a plurality of window frame/window piece assemblies can be fabricated in a single batch.

摘要： A drop-in environmental control material carrier assembly 55, which improves the performance and lowers the cost of semiconductor packages. The disclosed approach positions the environmental control materials inside the package cavity by means of a drop-in environmental control material carrier assembly 54, which can hold up to eight materials. In the case of a packaged micromirror, the getters consist of at least three types; i.e., (1) one for absorbing moisture inside the package, (2) one for absorbing adhesive outgassing constituents inside the package, and (3) one for storing the PFDA lubricant used to prevent the micromirror mirrors from sticking. The performance and lifetime of the micromirror devices are improved and the cost of projection display systems, in which these micromirrors are central components, is lowered. The preceding abstract is submitted with the understanding that it only will be used to assist in determining, from a cursory inspection, the nature and gist of the technical disclosure as described in 37 C.F.R. § 1.72(b). In no case should this abstract be used for interpreting the scope of any patent claims.

摘要： A package that resists creation of particles in a package cavity. A package according to one embodiment of the present invention contains a mechanical device attached to the floor of the package substrate. Epoxy typically is used to attach the device. Electrical connections are provided by bond wires connecting bond pads on the substrate with bond pads on the device. A window is attached to the substrate to form a cavity around the device. A thin masking layer on portions of the package cavity surface prevents the surface from generating particles. The thin masking layer may be any material that resists particle generation. The masking layer on the cavity walls optionally extends out of the cavity and onto the upper surface of the package.

摘要： An anchor to hold getter materials in place within a micromechanical device package substrate. First and second cavity faces define an anchor cavity and mechanically retain a getter away from a region holding the micromechanical device. The getter anchor may be formed in a substrate comprised of at least three layers. The layers form a cavity in the substrate with a wide bottom portion—formed in the middle layer and a relatively narrower top portion—formed by the top layer. The narrow portion helps to retain the getter in the cavity by creating a mechanical lock on the wide portion of getter in the bottom of the cavity.

摘要： A low-cost, high-performance, reliable micromirror package (300) that replaces the ceramic substrate in conventional packages with a printed circuit board substrate (30) and a molded plastic case (33), and the cover glass with a window (36), preferably an optically clear plastic window. The printed circuit board substrate (30) allows for either external bond pads or flex cable connection of the micromirror package to the projector's motherboard. These packages support flexible snap-in, screw-in, ultrasonic plastic welding, or adhesive welding processes to overcome the high cost seam welding process of many conventional packages.
