How to Resolve Vacuum Chamber Issues

Few issues haunt plasma processing quite like vacuum chamber problems. Plasma etching and plasma deposition tools require vacuum to be able to maintain the plasma and control the gas composition in the process. Other non-plasma deposition processes such as physical vapor deposition require a vacuum for the deposition species to reach the substrate without colliding with gas in the chamber. Creating and maintaining the vacuum can be complicated but is crucial to the success of the process....

3 Specialized Etch Processes for Photonics Fabrication

There are typical etch processes that are used in nearly every process flow, but there are also specialized etch processes that are specific to unique aspects of the application. Photonics manufacturing is no exception. Whether fabricating image sensors or photonic circuits, dry etch processes will be key to creating features with excellent optical properties....

How to Minimize Downtime for Etch and Deposition Equipment

Semiconductor plasma etch and deposition equipment has drastically different usage profiles when used in industry as compared to its use in research and academia. While the physics governs both applications, their end uses are different, and thus require different considerations for optimization....

Bringing Micro-lenses Into Focus

  It is not surprising that the scaling techniques used to enable Moore’s Law over the last several decades are being applied to similarly scale down the structures using macro-optics. As feature sizes of transistors have shrunk so that millions to billions of transistors fit on a chip, optical components have also been reduced in size. Many of these efforts are leading the way for advances in photonics. For example, chip-to-chip connections with relatively large fiber optics have evolved such that micron-sized chip-scale waveguides for making photonic based interconnects are now a possibility. Similarly, micro-lenses are opening up new applications that were once the domain of macro-lenses. This article introduces micro-lenses and how they are made using semiconductor processing techniques....
