Moore’s Law is dead, long live Moore’s Law – part 4

Moore’s Law is dead, long live Moore’s Law – part 4
by Scotten Jones on 04-21-2015 at 11:00 pm

In the third installment of this series we discussed the status of DRAM scaling and Moore’s law. In this installment we will tackle logic. The focus will be on foundry logic.

Logic technology challenges
In the second installment of this series we discussed constant electric field scaling. As we mentioned in that installment at … Read More

Moore’s Law is dead, long live Moore’s Law – part 3
by Scotten Jones on 04-19-2015 at 4:00 am

In the second installment of this series we reviewed the cost drivers that have enabled the semiconductor industry to continue to cost reduce the cost per transistor year after year. In the next three installments we will discuss the product specific issues beginning with this installment discussing DRAM.… Read More

Moore’s Law is dead, long live Moore’s Law – part 2
by Scotten Jones on 04-19-2015 at 12:00 am

In the first installment of this series on Moore’s law we examined what Moore’s law is and presented some data on how it has affected the industry. In this installment we will discuss the manufacturing cost reduction strategies that have made Moore’s law possible.

Manufacturing Cost Drivers
The manufacturing cost of a semiconductor… Read More

Moore’s Law is dead, long live Moore’s Law – part 1
by Scotten Jones on 04-15-2015 at 10:00 pm

April 19th is the fiftieth anniversary of Moore’s law! We thought it would be a good opportunity to reflect back on fifty years of Moore’s law, what it is, what it has meant to the industry, what the current status of the law is and what we may see in the future.

Moore’s law
Moore’s law is so well known that you wouldn’t think we would… Read More


Life Without EUV: SPIE Day 2

Life Without EUV: SPIE Day 2
by Scotten Jones on 03-29-2015 at 11:00 pm

I previously published a summary of day 1 of SPIE and I wanted to follow up with observations from successive days.

SPIE, the international society for optics and photonics, was founded in 1955 to advance light-based technologies.Serving more than 256,000 constituents from approximately 155 countries, the not-for-profit Read More


EUV Makes Progress and Other Observations From SPIE

EUV Makes Progress and Other Observations From SPIE
by Scotten Jones on 02-26-2015 at 1:00 pm

The SPIE Advanced Lithography Conference is the world’s premier conference for patterning techniques utilized to manufacture semiconductors. At any given time during the conference there are multiple parallel sessions so it is impossible to see all of the papers presented. Prior to the conference I reviewed and blogged on … Read More

by Scotten Jones on 11-17-2014 at 8:00 pm

The International Electron Devices Meeting (IEDM) is one of the premier conferences for the presentation of the latest semiconductor processes and process technologies. IEDM is held every year in December alternating between San Francisco and Washington DC. This year IEDM will be held at the San Francisco Hilton on December… Read More


Setting the Record Straight on FD-SOI Costs

Setting the Record Straight on FD-SOI Costs
by Scotten Jones on 07-20-2014 at 7:00 pm

I recently published an article on Semiwiki “Is SOI Really Less Expensive”. That article was the result of months of careful research and analysis. I looked at planar FDSOI versus bulk planar, bulk FinFETs and FinFETs on SOI at three different nodes. I took a consistent set of assumptions with respect to the fab used to run the processes,… Read More


Is SOI Really Less Expensive?

Is SOI Really Less Expensive?
by Scotten Jones on 06-24-2014 at 8:00 am

Introduction
There have been some claims made recently that planar Fully Depleted Silicon On Insulator (FDSOI) is less expensive than bulk planar processes and FinFETs at various nodes. Some of these claims suggest that FinFETs in particular are significantly more expensive. My company, IC Knowledge LLC produces the most widely… Read More
