    摘要: Semiconductor nano-sized particles possess unique optical properties, which make them ideal candidates for various applications in the UV photolithography. In this patent several such applications, including using semiconductor nano-sized particles or semiconductor nano-sized particle containing materials as highly refractive medium in immersion lithography, as anti-reflection coating in optics, as pellicle in lithography and as sensitizer in UV photoresists are described.

    摘要: 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 “open” state) or not transmit light to the wafer (referred to as its “closed” 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 “open” or “transparent” state of a shutter) or be “non-amplifying” (its “closed” or “opaque” 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 “programmable layer”. 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.

    摘要: Method and apparatus for exposing photo resists using programmable masks increases imaging resolution to provide fully dense integrated circuit patterns made of very small features on photoresist-coated silicon wafers by optical lithography. Small features are created by means of overlap exposure with either programmable or conventional masks. Blocking photoresists responding differently to two different wavelengths of light, two-color photoresists requiring two wavelengths of light to change solubility, and two-photon photoresists which change solubility only by absorbing two photons at a time may be used.
