Waiting for Porous Low-k
By Katherine Derbyshire - 12 May, 2011 - Comments: 0

I'm working on a longer article on low-k dielectric integration, but in the meantime I wanted to pass along an observation from Joubert Olivier of LTM-CNRS, in his presentation at the Materials Research Society Spring Meeting. Asked about the prospects for low-k integration, he reminded the audience that even if an integration scheme is able to achieve good selectivity between the hard mask ... » read more

Laser pulses illuminate downturn and recovery

[caption id="attachment_7313" align="alignnone" width="728"] Laser pulses per month for Gigaphoton's KrF and ArF lasers[/caption] I thought this image was a nice illustration of exactly what happened in the most recent industry downturn. The graphic shows the number of pulses per laser, per month, for Gigaphoton's installed base of ArF and KrF lasers. A stepper processing 1,000 wafers per mo... » read more

How do PV and IC silicon markets compare?
By Katherine Derbyshire - 14 Feb, 2011 - Comments: 0

The recent announcement of 2010 silicon wafer shipments got me wondering: silicon consumption for solar cells passed silicon consumption for integrated circuits a number of years ago, but how do they compare now? A quick call to the very helpful Richard Winegarner at Sage Concepts answered the question. In 2009, solar cells consumed 10 times as many square inches, but generated about the same t... » read more

From Your Tour Guide
