Silicon Photonics: Solving Process Variation and Manufacturing Challenges

By: Sandy Wen, Principal Engineer

As silicon photonics manufacturing gains momentum with additional foundry and 300mm offerings, process variation issues are coming to light. Variability in silicon processing affects the waveguide shape and can result in deviation in effective indices, propagation loss, and coupling efficiency from the intended design. In this article, we will highlight process variation issues that can occur in silicon photonics manufacturing and discuss techniques to mitigate these effects.

Are Good Engineers Born or Bred?

By Steve Breit, V.P. Engineering

I’ve been doing a lot of interviewing as we grow our engineering team. I often say that hiring is the most important part of my job and also the hardest part. Like any sensible technology company, Coventor wants to hire the best engineers we can find. Good engineers love engineering. They love to build, to create, to innovate, to solve problems. Good engineers are methodical and persistent, but also bring engineering judgment and intuition that helps them arrive at solutions efficiently. Good engineers can’t help doing engineering – it’s who they are. Over the years, I’ve observed that good engineers are way more productive than mediocre engineers. The difference in productivity can be astounding, in excess of 2 or 3X for the best engineers. The trick, at least during the hiring process, is to discern which candidates are the good engineers. You can’t just look at academic degrees, skills claimed, or work experience to tell the difference. read more…

The Future of MEMS Design: Making MEMS Design More Like CMOS Design

By: Christine Dufour, MEMS PDK Program Manager

MEMS-based component suppliers want to rapidly ramp their designs into high-volume production.  This demand is driving MEMS suppliers to focus on ways to more efficiently re-use established process steps, stacks or technology platforms. To meet this need, we see the emergence of standard MEMS technology and design platforms similar to those used in CMOS design.

The semiconductor industry and EDA vendors have established integrated design environments based on PDKs (Process Design Kits), standard cell libraries, memory architectures, and IP, to give easy access to the technology for IC designers and increase chances of first-pass successful silicon. Coventor’s vision is that the MEMS eco system and MEMS EDA software vendors should play a similar role in accelerating MEMS product development. read more…
