- You are right. I re-wrote that paragraph. Glaurung 06:25, 25 October 2006 (UTC)
(old chat not related to improvement of the page)
i am depositing gold film of 0.5 micron thickness over a pattrened wafer which is thereafter going for bulk micromachining in KOH solution. i am obeserving that gold is pilling out form the surface where beneath layer is silicon. is it possible that Au adhesion is poor with Silicon, or the pin holes are main culprit in this. please suggest.
- Au adhesion is known to be poor on Si. Try a thin Cr or Ti underlayer first as they will bond more strongly the with the native oxide on the Si. 5 nm should be enough. Alison Chaiken 14:59, 27 January 2006 (UTC)
hmm
MEMS is also the acronym for a middle school in New Jersey- Manalapan-Englishtown Middle School
Microsystem technology
I have doubt about the new sentence that was added : In Europe, MEMS are often referred to as Micro Systems Technology (MST). I have personally never heard these words when talking about MEMS, and I was told they were only used by German-speaking people as a direct translation of Mikrosystemtechnik. 07:07, 28 February 2006 (UTC)
- That may be true. I was doing an edit of the MST accronym page and the first entry was Micro Systems Technology. I had a look at the Micro Systems Technology page -- here is what I saw orginally [2] -- it just said it was a European name for MEMS. I figured why have a separate article of two sentences, why not just a redirect and explain that MEMS has another name in Europe. If you feel it is wrong we can change it. --Ben Houston 15:47, 28 February 2006 (UTC)
- Before writing on this talk page, I looked at the edits to see where the info was coming from and I saw what you did. I should have made it clearer that I was in no way pointing at you personally with my remark. The original edit was made by an anonymous user, so we don't know where he is coming from and what his sources are. It would be interesting to have information from Europeans wikipedians with knowledge about MEMS, to decide whether MST is widely used in Europe or only in German-speaking countries. All I can say is that in the French-speaking part of Switzerland, we do not use microsystem technology, but I would not take this as a reference. Glaurung 07:10, 2 March 2006 (UTC)
- Ah, I understand. Well, I just did a search and there is a quite a few mentions of "Microsystem technology" on the web (16,100 if I exclude wikipedia related results)and there seems to be a few research groups that use that name [3], [4], [5] (the page title is MEMS, the title within the body is "Micro-Systems Technology".) The term's popularity via Google, even if it is semi-equivalent, is 1000x less than MEMS. Thus I think it warrents a redirect and a very brief mention. --Ben Houston 16:06, 2 March 2006 (UTC)
- Accodrind to your links, it is also used in England, so European seems to be applicable. (On a side note, one of your link is in S. Korea, so MST may be even more widely distributed.) A redirect to MEMS, is naturalle very suitable in this case. Glaurung 06:55, 3 March 2006 (UTC)
- I believe MEMS are known as microsystems in Europe. A new EU-backed activity called STIMESI (Stimulation Action for Microsystems and System and Package)has recently started up.

Introduction
Consider starting the intro with something a little more layman friendly. I'm an engineering student and I was getting lost by the second sentance. I imagine someone with a non-technical background will get even less out of it.
My suggestion would be start of with the applications and especially the motivation for using mems over older technologies that could perform the same tasks. it seems like this could be seperated from the manufacturing details that are currently in the introduction.
External links
The external links are getting too numerous (if one follows WP:EL). However, due to the diversity of the field I think we can live with an above-average number of links, at least until the wiki content has expanded reasonably. In the meantime, I have started some cleaning by separating research institutions from foundries, and skipping vendors (actually one so far) of MEMS based systems. --DrTorstenHenning 11:30, 7 August 2006 (UTC)
- Someone keeps adding a particularly annoying link to memsinvestorjournal.com, misleadingly labelled as "Interviews with MEMS industry leaders", while this site is in fact just another newsletter on MEMS. It is my interpretation of WP:EL that, since we cannot have a list of all the newsletter sites in the world, we should have none such sites. Any opinion on this? --DrTorstenHenning 08:02, 17 August 2006 (UTC)
- OK, seems I'm only talking to myself here, yet the link list keeps growing and growing. I've marked it for cleanup, and will give it some time before actually cleaning up this messy dump of links. --DrTorstenHenning 12:59, 26 August 2006 (UTC)
I concur too many external links... but the page is so poorly written that, well, as a temporary measure it is not too bad. Interestingly there are a few links that have been removed which could have been left (including one to a site I maintain A (not so) short introduction to MEMS, which, well, in all objectivity :-), was probably useful, but there was at least another one to a good online intro that has been removed too...). I let you judge what is worth including - but chop the list!
- I inserted that link you mentioned (less the typo:-) I agree that as long as nobody takes the time to thoroughly rewrite this article, the links are better than nothing. I just try to keep the links sorted, so that NPOV info sites do not get mixed up with commercial interest motivated web sites. Wish I had more time at hand ... --DrTorstenHenning 16:48, 20 September 2006 (UTC)
Electro-mechanical coupling
Many MEMS devices are based on electro-mechanical coupling but that is not mentioned on the page. Also one could add the fields of physics which MEMS devices combine: electromagnetics, solid mechanics, fluid dynamics, and heat transfer. There's quite a lot of text on the manufacturing side but not so much on the operating principles. Do you think it would be helpful to add something on these? -[Apursula, 28-Aug-2006]
- Definitely yes, this article aought to be expanded considerably. So far, most of the edits have consisted of dumping ever more external links. I wish I had more time at hand right now, so please go ahead and add the things you mentioned. --DrTorstenHenning 12:13, 28 August 2006 (UTC)
