Nowadays, novel semiconductor technologies have brought complex process flows to the fab.   These process flows are needed to support the manufacturing of advanced 3D semiconductor structures. It can be helpful to model process flows, and their effect on a novel device, prior to physical fabrication.

Photonics in Silicon R&D Toward Tb/s

By Ed Korczynski, Sr. Technical Editor, Semiconductor Manufacturing & Design

The client:server computing paradigm colloquially referred to as the “Cloud” results in a need for extremely efficient Cloud server hardware, and from first principles the world can save a lot of energy resources if servers run on photonics instead of electronics. Though the potential for cost-savings is well known, the challenge of developing cost-effective integrated photonics solutions remains. Today, discrete compound-semiconductor chips function as transmitters, multiplexers (MUX), and receivers of photons, while many global organizations pursue the vision of lower-cost integrated silicon (Si) photonics circuits. read more…

Design Process Technology Co-Optimization for Manufacturability

By:   Dalong Zhao – Semiconductor Process & Integration Engineering

Yield and cost have always been critical factors for both manufacturers and designers of semiconductor products.   Meeting yield and product cost targets is a continuous challenge, due to new device structures and increasingly complex process innovations introduced to achieve improved product performance at each new technology node.  Design for manufacturability (DFM) and design process technology co-optimization (DTCO) are widely used techniques that can ensure the successful delivery of both new processes and products in semiconductor manufacturing.   In this article, we will discuss how 3D (3 dimensional) DTCO can be used to improve product yield and accelerate product delivery dates in semiconductor manufacturing. read more…

In March 2016, Coventor was invited to the biannual Partner Technical Week (PTW) at IMEC in Leuven, Belgium. IMEC, a world-leading research group in nanotechnology, organizes their Partner Technical Week every 6 months to present scientific results to their partners. During this week, a number of specialists from IMEC’s many partner companies also discuss their progress in areas related to IMEC’s research. This event brings together a large number of engineers who are specialists in their domain, and provides an interesting forum to leverage the scientific knowledge gained by IMEC and its partners. read more…

Inside Process Technology

se_logo

By Mark Lapedus

Semiconductor Engineering sat down to discuss the foundry business, memory, process technology, lithography and other topics with David Fried, chief technology officer at Coventor, a supplier of predictive modeling tools. What follows are excerpts of that conversation.

SE: Chipmakers are ramping up 16nm/14nm finFETs today, with 10nm and 7nm finFETs just around the corner. What do you see happening at these advanced nodes, particularly at 7nm?

Fried: Most people are predicting evolutionary scaling from 14nm to 10nm to 7nm. It’s doubtful that we will see anything really earth-shattering in these technologies. And so, a lot of the challenges come down to patterning. We are going to see multi-patterning schemes really take hold at more levels. For example, the fins are now based on self-aligned double patterning. People will move into self-aligned quad patterning. The gates are maybe self-aligned double. Now, they will move into self-aligned quad. So, that’s going to be a big expense, because each level is going to have multiple passes and multiple cuts.
