HIGH-VOLUME OPTICS FABRICATION: New technologies enable precise and cost-effective wafer-level optics
نویسنده
چکیده
Widespread deployment of cameras in consumer products–most noticeably cell phones–has lead to a quest for improved cost efficiency in all manufacturing steps. Wafer-level manufacturing and assembly seems to offer a way forward for cost reduction. Whereas CMOS image sensors are already exclusively manufactured at the wafer level, this is not true for the lens stacks used in consumer cameras. There are a number of key challenges related to wafer-based manufacturing of camera lenses–including lens design, tooling, replication, metrology, and cost of ownership (see Fig. 1).

Post-Processed Integrated Microsystems
This report represents the completion of a three-year Laboratory-Directed Research and Development (LDRD) program to develop a low cost platform for integrated microsystems that is easily configured to meet a wide variety of specific applications-driven needs. Once developed, this platform, which incorporates many of the elements that are common to numerous microsystems, will enable integrated ...
متن کاملDiffraction-limited performance of flat-substrate reflective imaging gratings patterned by DUV photolithography.
We report on the first demonstration of flat substrate imaging gratings fabricated by deep ultraviolet (DUV) photoreduction lithography, which uniquely offers sub-100-nm resolution and spatial coherence over centimeter scales. Reflective focusing gratings, designed according to holographic principle, were fabricated on 300-mm silicon wafers by immersion DUV lithography. Spatial coherence of the...
متن کاملImprint lithography for integrated circuit fabrication
The escalating cost for next generation lithography ~NGL! tools is driven in part by the need for complex sources and optics. The cost for a single NGL tool could exceed $50M in the next few years, a prohibitive number for many companies. As a result, several researchers are looking at low cost alternative methods for printing sub-100 nm features. In the mid-1990’s, several research groups star...
متن کاملNanoimprint lithography for nanodevice fabrication
Nanoimprint lithography (NIL) is a compelling technique for low cost nanoscale device fabrication. The precise and repeatable replication of nanoscale patterns from a single high resolution patterning step makes the NIL technique much more versatile than other expensive techniques such as e-beam or even helium ion beam lithography. Furthermore, the use of mechanical deformation during the NIL p...
متن کاملCost-effective CMOS-compatible grating couplers with backside metal mirror and 69% coupling efficiency.
A highly efficient grating structure for the coupling between standard optical fibers and single-mode waveguides in the silicon-on-insulator platform realized in a CMOS fabrication process is presented. The cost-effective method introduces a backside metal mirror to the grating coupler without need of an extensive wafer-to-wafer bonding. A coupling efficiency of -1.6 dB (around 69%) near the te...
