Manufacturing Bits: Feb. 4

By Mark LaPedus - 04 Feb, 2014 - Comments: 0

Secrets of mass variation The General Conference on Weights and Measures will soon approve a plan to redefine the kilogram and other measurement units. The new definition for the kilogram will be based on the fixed numerical values of Planck’s constant (h). Supposedly, the new definition will solve the current problem. The kilogram is the only SI unit that is still described as an artif... » read more

Week In Review: Manufacturing, Design, Test

By Mark LaPedus - 31 Jan, 2014 - Comments: 0

The technology of 3D "bioprinting" (the medical application of 3D printing to produce living tissue and organs) is advancing so quickly that it will spark a major ethical debate on its use by 2016, according to Gartner. At the same time, 3D printing of non-living medical devices such as prosthetic limbs, combined with a burgeoning population and insufficient levels of healthcare in emerging mar... » read more

Manufacturing Bits: Jan. 28

Spintronics gains traction The field of spintronics is gaining interest. The technology could enable a new class of spin-based devices, which combine the switching speeds of logic and the non-volatility of memory. Controlling the magnetism by means of electric fields is the key for future devices, but the ability to switch ferromagnetism technology at room temperature is challenging. Helmho... » read more

What’s After CMOS?

By Mark LaPedus - 24 Jan, 2014 - Comments: 3

Chipmakers continue to scale the CMOS transistor to finer geometries, but the question is for how much longer. The current thinking is that the CMOS transistor could scale at least to the 3nm node in the 2021 timeframe. And then, CMOS could run out of gas, prompting the need for a new switch technology. So what’s after the CMOS-based transistor? Carbon nanotubes and graphene get the most a... » read more

Look for a nasty political campaign in Idaho, according to Bloomberg. Business leaders from Micron Technology and others in Idaho are endorsing the incumbent Republican candidate over a Tea Party challenger. The challenger, Bryan Smith, is a conservative Republican running for Idaho’s second congressional district. He is running against 16-year incumbent Mike Simpson. Simpson is supposedly pr... » read more

Waiting For Next-Generation Lithography

By Mark LaPedus - 23 Jan, 2014 - Comments: 2

Nearly 30 years ago, optical lithography was supposed to hit the wall at the magical 1 micron barrier, prompting the need for a new patterning technology such as direct-write electron beam and X-ray lithography. At that time, however, the industry was able to push optical lithography for volume chip production at the 1-micron node and beyond. This, in turn, effectively killed direct-write e-... » read more

The Bumpy Road To 3D NAND

By Mark LaPedus - 23 Jan, 2014 - Comments: 1

The NAND flash memory market is dynamic, but it’s also sometimes predictable. Suppliers tend to roll out identical NAND flash chips and then scale them to smaller geometries. And NAND chip prices rise and fall, depending on the supply/demand equation at a given point. Going forward, though, the NAND market is expected to become less predictable, if not chaotic, amid a new and major technol... » read more

Executive Viewpoint: Qualcomm On Process Technology

By Mark LaPedus - 23 Jan, 2014 - Comments: 3

Semiconductor Engineering sat down to discuss current and future process technology challenges with Geoffrey Yeap, vice president of technology at Qualcomm. SE: You have pointed out there is a fundamental shift taking place at the 28nm logic node. This is the first node in which mobile chips have been ramped up first within the foundries, ahead of computing-based ICs. Many believe that 28nm ... » read more

Fab Tool Industry Has Lost Its Way

By Mark LaPedus - 23 Jan, 2014 - Comments: 1

The relationship between chipmakers and fab tool vendors has always been a bit rocky, but the supply chain has generally worked. Chipmakers demand a tool for a particular application. Then, tool makers attempt to deliver the goods, and ask few, if any, questions. Now, fab tool executives are beginning to ask some tough questions about the industry. And the tension is mounting between equ... » read more

Manufacturing Bits: Jan. 21

Redefining The Kilogram In 2011, the General Conference on Weights and Measures approved a plan to redefine the kilogram and other measurement units. The new definition for the kilogram will be based on the fixed numerical values of Planck’s constant (h), according to the National Institute of Standards and Technology (NIST), part of the U.S. Department of Commerce. NIST has taken steps t... » read more
