Talk:High-κ dielectric

message: Old article was a mess.  I took out the way-too-long list of binary high-k candidates and took out rumors about this and that company using high-k materials.  I also added material on oxynitride gate dielectrics but it needs citations. Irene Ringworm 05:04, 5 February 2007 (UTC)

thread_title: Complete rewrite

message: I have stuck a current tag on the article in light of Intel's press release that they will incorporate high-k dielectrics in their chips. I guess it should stay for a week or so, or at least until further technical details become clear (which compound of Hf?...) 212.2.177.248 11:16, 28 January 2007 (UTC)

message: # How to pronounce the name High-κ? "high-k" or "high-kappa"?
# What about renaming this article to "High-κ Dielectrics"?
::  Pronunciation is "High-kay", can clarify in main article.  I'm okay with the renaming.  Irene Ringworm 00:56, 14 January 2007 (UTC)
replies: text:  Oppose renaming.  In my experience, electrical engineers call the relative dielectric constant 'k', not 'κ' (and pronounce the name accordingly). --Smack (talk) 18:39, 18 January 2007 (UTC)
replies: text:  I also oppose renaming and would further add that all the uses of 'κ' be replaced with 'k'.  Wikipedia seems to be the only one perpetuating that convention. I'll checkl back in a couple days.  If no objection I'll do it.  Alexa411 18:19, 17 May 2007 (UTC)

message: Can somebody please extend the application/use section to include other common uses of high-k materials such as for capacitors and electricity storage devices.  —Preceding unsigned comment added by 66.46.103.18 (talk) 18:31, 21 May 2008 (UTC)

thread_title:  Cookies required? 

message: The complaint about this article being "grossly out of date" is itself grossly out of date.  Why hasn't this article been substantially edited in seven years? I thought wikipedia is supposed to have very updated articles.  — Preceding unsigned comment added by 50.162.29.18 (talk) 16:38, 14 March 2014 (UTC)
thread_title:  Grossly out of date 

message: My memory on this is rusty, but as I remember, gate capacitance should be low, such as the previous stage doesn't need to pump a lot of current to fill this cap. As I understand it, high-k provides for lower leakage (desired), at the possible _expense_ of higher capacitance.
Also, the picture shows high-k dielectric at 3nm, thicker than traditional SiO2 1,2nm.
Please take a look...  —Preceding unsigned comment added by 95.76.30.38 (talk) 21:03, 24 December 2009 (UTC)
thread_title:  Higher gate capacitance is desirable?? 

message: What range of K constitutes high K? Is 50 high K? 100? 1000? There must be at least a rough cut-off.  — Preceding unsigned comment added by 192.12.184.6 (talk) 22:04, 9 July 2012 (UTC)
thread_title:  How is high-k? 

message: To anyone who can be arsed to clean this mess up:
1. 'High-k dielectric' is a simple electronic material property. I was taught at university that it commonly refers to a material with at least an order of magnitude greater permittivity than free space or equivalently, a k factor of 10 or more. This term has been used in reference to various metal oxides and glasses for a very long time.
2. The microelectronics industry has a special definition which is solely used in Si based electronics such as MOSFET gates. Please see: http://www.semi1source.com/notes/ViewFile.asp?Which=30
Quote: / In Si technology the reference is a value of k of silicon dioxide, SiO2, which is 3.9. Dielectrics featuring k>3.9 are referred to as “high”-k dielectric while dielectric featuring k<3.9 are defined as “low”-k dielectrics. /
So basically, in this context 'high-k' refers to 'higher k than SiO2'.
Good luck!
Whoever deleted the original list should hang his head in shame. I suspect that he ran a google search and since the only results he could be bothered to look at were only talking about gate dielectrics, he assumed that this was its only meaning.

thread_title:  Needs rewriting for clarity and redefinition. 

message: Reason: real name of technology with κ not k (redirect will take care of it)
got:
"High-k dielectric" cannot be moved to "High-κ dielectric", because the title "High-κ dielectric" is on the title blacklist.
Maybe best to keep unchanged even if an exception is allowed? Doesn't matter much to me. comp.arch (talk) 10:05, 20 September 2013 (UTC)
thread_title:  Article rename 

message: ::Silicon dioxide has been used as a gate oxide material for decades. As transistors have decreased in size, the thickness of the silicon dioxide gate dielectric has steadily decreased to increase the gate capacitance and thereby drive current, raising device performance
The gate (width) size has decrease, but the corresponding increase in gate capacitance is not desired, and does not give better performance - it gives higher switching losses.  — Preceding unsigned comment added by 83.100.174.82 (talk) 17:15, 12 June 2015 (UTC)
