A Review of Silicon Photonics: Using Process Simulation to Design Silicon Photonics Devices

By: Michael Hargrove, SP&I Engineer

With the end of Moore’s Law rapidly approaching, or as some folks say – “already here”, new applications of older technologies are gaining attention. One specific area of interest is photonics. The National Center for Optics and Photonic Education defines photonics as the technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. It can also be defined as the science and application of light. Photonic applications use the photon in the same way that electronic applications use the electron. So, it’s natural to think of photonic applications in a similar manner as we think of electronic applications. The connection back to Moore’s Law is that we want to integrate photonic structures on a typical silicon wafer, utilizing Si-based technology that the industry has been continually shrinking and improving. This aspiration has led to the creation of silicon photonics technology, where photonics structures are built directly onto silicon wafers. read more…

How To Build A Better MEMS Microphone

By: Chris Welham, Senior Manager, MEMS Applications Engineering

A Section of a MEMS Microphone Model

Overview

Here at Coventor, we are seeing a lot of interest in simulating noise, particularly for condenser microphones. With any transducer noise reduction is always a plus, and with microphones there are two specific applications that need low noise. One is where the microphone is positioned away from the sound source, such as in video calling or when using voice commands with tablet computers. The other is where multiple microphones are positioned in an array, to detect the direction of incoming sound or for noise canceling applications. read more…

Comparing MEMS and the RMS Titanic: Some Thoughts from the IEEE MEMS 2018 Conference

By: Chris Welham, Sr. Manager, MEMS Applications Engineering

How are MEMS and Large Ships Alike?

MEMS 2018 was held in Belfast, Northern Ireland this year, on the site where the RMS Titanic was built. On exhibit was the SS Nomadic, a tender used to transfer mail and passengers to the RMS Titanic and her sister ship RMS Olympic. Passing by the SS Nomadic on the way to the conference dinner, I noticed the riveted plates from which the tender was built. These riveted plates reminded me of the finite element plate models used in the MEMS+ module of CoventorMP, which can also be joined to other elements using “connectors” or “nodes” rather than rivets. read more…

Future Outlook: The Advantages of Fully Depleted Silicon on Insulator (FD-SOI) Technology

By: Michael Hargrove, SP&I Engineer

If my memory serves me well, it was at the 1989 Device Research Conference where the potential merits of SOI (Silicon on Insulator) technology were discussed in a heated evening panel discussion. At that panel discussion, there were many advocates for SOI, as well as many naysayers. I didn’t really think more about SOI technology until the mid-nineties, when I was sitting in a meeting where the first SOI device data was being presented in the hallowed halls of IBM. The data was incredibly scattered and my thinking was “this technology is going nowhere!” The purported performance advantage was stated to be ~35%, simply due to the capacitance reduction (no longer did the bottom junction capacitance play a role) and the speed advantages of stacked devices in a NAND circuit. It all sounded great, but in the mid-nineties, the data simply didn’t support it. Nonetheless, the SOI advocates pursued their beloved technology, and the rest is history. SOI technology has been part of IBM’s main stream high-performance technology base through the 14nm node, including FinFETs on SOI. read more…

What the Experts Think: Delivering the Next 5 Years of Semiconductor Technology

Coventor recently sponsored an expert panel discussion at IEDM 2017 to discuss how we might advance the semiconductor industry into the next generation of technology.  The panel discussed alternative methods to solve fundamental problems of technology scaling, using advances in semiconductor architectures, patterning, metrology, advanced process control, variation reduction, co-optimization and new integration schemes.  Our panel included Rick Gottscho, CTO of Lam Research; Mark Dougherty, vice president of advanced module engineering at GlobalFoundries; David Shortt, technical fellow at KLA-Tencor; Gary Zhang, vice president of computational lithography products at ASML; and Shay Wolfling, CTO of Nova Measuring Instruments.

CMOS Image Sensors (CIS): Past, Present & Future

By: Sofiane Guissi, Semiconductor Process & Integration Engineer, Coventor

Over the last decade, CMOS Image Sensor (CIS) technology has made impressive progress. Image sensor performance has dramatically improved over the years, and CIS technology has enjoyed great commercial success since the introduction of mobile phones using on-board cameras. Many people, including scientists and marketing specialists, predicted 15 years earlier that CMOS image sensors were going to completely displace CCD imaging devices, in the same way that CCD devices displaced video capture tubes during the mid-1980’s. Although CMOS has a strong position in imaging today, it has not totally displaced CCD devices. On the other hand, the drive into CMOS technology has drastically increased the overall imaging market. CMOS image sensors have not only created new product applications, but have also boosted the performance of CCD imaging devices as well. In this paper, we describe the state-of-the-art in CMOS image sensor technology and discuss future perspectives.
