Infineon Announces 300 mm Thin Wafers
Infineon says it is the first company to have successfully produced chips on 300 mm thin wafers, which will be used for high-voltage semiconductors.
According to the manufacturer, these Metal Oxide Semiconductor Field-Effect Transistors (MOSFETs) offer the same behavior as those previously manufactured on 200 mm wafers (in diameter, not thickness), but will enable the company to produce the chips much more efficiently.
“Our engineers’ achievement marks a quantum leap in production technology,” said Reinhard Ploss, Operations, Research & Development and Labor Director at Infineon Technologies. “Innovation lays the foundation for profitable growth. Innovation secures our edge over the competition.”
300 mm wafers have been used for common chips such as CPUs for more than a decade, but certain individual segments still rely on 200 mm technology as the production volume does not justify a switch to the more expensive 300 mm technology.
However, Infineon had the advantage of already having a 300mm production plant; the thin wafers are produced in the former Qimonda DRAM plant in Villach, Austria.
Im guessing this move is mainly so they can stack more layers in memory chips. You can only stack so thick before you run into thermal problems.
what? molecular leap?

From what I read for SEMI specifications here:
http://www.virginiasemi.com/pdf/semi%20specificationsoverview71002.pdf
300mm diameter (+/-0.2mm)
775um thickness (+/-20um)
um = .001mm
yes, but i don't get why this is special, as there are already 300mm being used.
i skimmed the pdf in case that had anything that told me the relevance besides the yeilds and cost.
nanoleap?
As for term of quantum im not sure. Usually think within the idea of usage within termanology or the like usually has a varying place of say use. To say on some ideas the use of such might have more then one appliance of such within for a use, might be say "quantum" within its own use or say, maybe more towards say of use of course though. I don't know though for the most part either probably to a decent point.
Think quantum usually places alot of interest within deeper interest of say studies more then not, namely some form of one more then another. Maybe not though as well, and the usejust finds a fitting for what the intial interest of the say "term" implies or applies too.
More lost on MOSFETs then anything, for interest of like wafers nd the such might be placed within ideas of the same within interest of relating place of use for one, I don't know. Think had thought it was a brand name/brandname more then anything.

Apparently they are getting up to 25% power efficiency with this new THINNER wafer. I have worked with 300mm wafers since 2002, so the technology in making chips on 300mm has been in use since about 2000-2001 or so. They are just using a thinner wafer to produce a more power efficient chip, from what I've read.
Here's a link to Infineon's article about it:

In other words, yes he recognizes that this is no big deal, hence it is a quantum leap (very small and unimportant).
