    Abstract: Light-emitting devices and methods of making the same are described whereby lenses of any array include a material with a higher refractive index than an encapsulation layer of a substrate layer, the refractive index of the material being in a range of greater than 1.7 to 1.9 at 400 nm. The material forming the lenses includes nanocomposite comprised of inorganic nanocrystals and a polymeric matrix, wherein the nanocrystals are selected from the group consisting of ZrO2, ZnO, MgO, HfO2, NbO5, Ta2O5 and Y2O3. A 3-4 micron thick sample of the nanocomposite has an optical transmittance of at least 80% over a range of 440 nm to 800 nm.

    Abstract: The present invention overcomes many of the disadvantages of prior lithographic microfabrication processes while providing further improvements that can significantly enhance the ability to make more complicated semiconductor chips at lower cost. A new type of programmable structure for exposing a wafer allows the lithographic pattern to be changed under electronic control. This provides great flexibility, increasing the throughput and decreasing the cost of chip manufacture and providing numerous other advantages. The programmable structure consists of an array of shutters that can be programmed to either transmit light to the wafer (referred to as its nullopennull state) or not transmit light to the wafer (referred to as its nullclosednull state). The programmable structure can comprise or include an array of selective amplifiers. Thus, each selective amplifier is programmed to either amplify light (somewhat analogous to the nullopennull or nulltransparentnull state of a shutter) or be nullnon-amplifyingnull (its nullclosednull or nullopaquenull state). In the non-amplifying state, some portion of the incident light is transmitted through the amplifier material. The shutters and selective amplifiers can work in tandem to form a nullprogrammable layernull. A programmable technique is provided for creating a pattern to be imaged onto a wafer that can be implemented as a viable production technique. Thus, the present invention also provides a technique of making integrated circuits. A diffraction limiter can be used to provide certain advantages associated with contact lithography without requiring some of the disadvantages of contact lithography.

    Abstract translation: 本发明克服了现有的平版印刷微细加工工艺的许多缺点，同时提供了可以以更低成本显着提高制造更复杂的半导体芯片的能力的进一步改进。 用于曝光晶片的新型可编程结构允许在电子控制下改变光刻图案。 这提供了极大的灵活性，增加了生产量并且降低了芯片制造的成本并且提供了许多其他优点。 可编程结构由一组快门组成，可以被编程为将光传输到晶片（称为其“打开”状态）或不将光传输到晶片（称为其“关闭”状态））。 可编程结构可以包括或包括选择放大器的阵列。 因此，每个选择放大器被编程为放大光（有点类似于快门的“打开”或“透明”状态）或者是“非放大”（其“闭合”或“不透明”状态））。 在非放大状态下，入射光的一部分透过放大器材料。 快门和选择放大器可以串联工作以形成“可编程层”。 提供了一种可编程技术，用于创建可被实现为可行的生产技术的要被成像到晶片上的图案。 因此，本发明还提供了制造集成电路的技术。 衍射限制器可以用于提供与接触光刻相关联的某些优点，而不需要接触光刻的一些缺点。
