Readers of SemiWiki will be well aware of the challenges the industry has faced in photolithography in moving to new nodes, which drove the development of new EUV light sources as well as new masking techniques. Plasma etching is another key step in chip manufacturing that has also seen new challenges in the development of new sub-10nm… Read More

SISPAD – Cost Simulations to Enable PPAC Aware Technology Development
I was invited to give a plenary address at the SISPAD conference in September 2021. For anyone not familiar with SISPAD it is a premiere TCAD conference. This year for the first time SISPAD wanted to address cost and my talk was “Cost Simulations to Enable PPAC Aware Technology Development”.
For many years the standard in technology… Read More
Webinar on coping with the complexities of 3D NAND design
In order to beat Moore’s Law NAND Flash memories have moved from a planar topology to 3D construction. This allows for increased memory sized in much the same way a multistory building provides more building square footage on the same size building lot. Just like in building construction, adding a third dimension to the mix increases… Read More
Webinar – 3D NAND Memory Cell Optimization
Flash memory has become ubiquitous, so much so that it is easy to forget what life before it was like. Large scale non-volatile storage was limited spinning disks, which were bulky, power hungry and unreliable. With NAND Flash, we have become used to carrying many gigabytes around with us all the time in the form of cell phones, USB… Read More
Silvaco Talks Atoms to Systems – Where to Next?
At the ES Design West event in San Francisco last week Silvaco’s CTO and EVP of Products, Babak Taheri, gave a presentation titled, “Next Generation SoC Design: From Atoms to Systems”. The time slot for the talk was only 30-minutes which is simply not enough to discuss all the technology Silvaco is providing now. I had not looked closely… Read More
Where Circuit Simulation Model Files Come From
I started out my engineering career by doing transistor-level circuit design and we used a proprietary SPICE circuit simulator. One thing that I quickly realized was that the accuracy of my circuit simulations depended entirely on the model files and parasitics. Here we are 40 years later and the accuracy of SPICE circuit simulations… Read More
Advanced Materials and New Architectures for AI Applications
Over the past 50 years in our industry, there have been three invariant principles:
- Moore’s Law drives the pace of Si technology scaling
- system memory utilizes MOS devices (for SRAM and DRAM)
- computation relies upon the “von Neumann” architecture
Using a TCAD Tool to simulate Electrochemistry
In college I took courses in physics, calculus, chemistry and electronics on my way to earn a BSEE degree, then did an 8 year stint as a circuit designer, working at the transistor level and interacting with fab and test engineers. My next adventure was working at EDA companies in a variety of roles. As a circuit designer I knew that … Read More
Webinar on Electrochemistry and how it affects Semiconductor devices
My educational background is Electrical Engineering and I’ve learned a lot since starting in the industry back in 1978 while working on bipolar, NMOS and CMOS technology, designing DRAM, data controller and GPU devices. I continue to learn about the semiconductor industry through daily reading and attending trade shows… Read More
TCAD for TFT, LCD and OLED Displays
As I write there are multiple displays in front of me that use TFT, LCD or OLED displays:
- ViewSonic Monitors with 24″ display
- MacBook Pro with 15″ display
- iPad Air
- Samsung Galaxy Note 4
- Nexus 7 tablet
- Garmin Edge 820
