  • FilmTek Autoloader, CD
Apr 2008
Scientific Computing InternationalRequest Info
CARLSBAD, Calif., April 30, 2008 -- Scientific Computing International (SCI) has introduced a wafer autoloader option and a CD for tabletop FilmTek metrology models.

SCI said the FilmTek autoloader is designed as a cost-effective option to increase instrument throughput and automation while avoiding the price and complexity of a fully automated, stand-alone system. With a small footprint, the FilmTek autoloader has a load/unload cycle time on the order of a few seconds and dramatically increases wafer throughput for economical tabletop instruments. The autoloader option is available for 4-to 8-in. wafer sizes and is compatible with all tabletop FilmTek instruments.

The FilmTek CD, for nondestructive optical CD and thin-film metrology applications, accurately and simultaneously determines top and bottom linewidth, sidewall angle including negative slope, and trench depth, in addition to film thickness and index, the company said. Based on normal incidence ellipsometry, the FilmTek CD provides highly accurate measurements with fast data acquisition times.

The CD includes proprietary diffraction software with real-time optimization. In what SCI said is an industry first, that real-time optimization allows the user to easily measure unknown structures with minimal setup time and recipe development while avoiding the time and complexity associated with library generation.

FilmTek CD provides detailed profile information for gate and shallow trench isolation (STI) structures, as well as contact holes, vias, and deep isolation trenches. It can also measure depth for a single trench structure. The normal incidence ellipsometric design makes the FilmTek CD ideally suited for the extremely small linewidths encountered at the 45-nm and 32-nm technology nodes, according to the SCI.

Available as an economical benchtop unit or as a fully automated stand-alone system with cassette-to-cassette wafer handling, FilmTek CD can be configured to suit a range of budgets and end-use applications, the company said.

As a wavefront of light passes by an opaque edge or through an opening, secondary weaker wavefronts are generated, apparently originating at that edge. These secondary wavefronts will interfere with the primary wavefront as well as with each other to form various diffraction patterns.  
The science of measurement, particularly of lengths and angles.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
A cross-sectional slice cut from an ingot of either single-crystal, fused, polycrystalline or amorphous material that has refined surfaces either lapped or polished. Wafers are used either as substrates for electronic device manufacturing or as optics. Typically, they are made of silicon, quartz, gallium arsenide or indium phosphide.
