XRAY photo of Transistors[edit]

Something like this would be educational for this article, actually XRAY of all electronic parts would be very interesting for all electronic part articles on Wikipedia. If anyone has any XRAY photos with the correct "rights", please upload and add to appropriate Wiki article. Thanks! • SbmeirowTalk • 03:34, 18 November 2015 (UTC) : Xray of TO-92 transistor package - https://c2.staticflickr.com/4/3040/3574799585_e8270b0531_z.jpg?zz=1

You could e-mail the Flickr uploader. I have had a good deal of success in the past with Flickr users getting them to change the licence once I explained what I wanted to do with the image. No guarantee of course, it's entirely up to them. SpinningSpark 15:12, 18 November 2015 (UTC)
It might be more useful to get a picture with the package removed. Too bad I don't have a lens that can focus that close. Jc3s5h (talk) 17:25, 18 November 2015 (UTC)
There is already one in the article of a Darlington transistor. I'm pretty sure that there are some more on Commons. SpinningSpark 17:44, 18 November 2015 (UTC)
I am not sure whether an Xray photo is helpful as it just shows the copper contacts. If you like to show internals, you need to open a metal case or use nitric acid to remove the plastic shelf. Schily (talk) 10:46, 19 November 2015 (UTC)

Multiple-emitter ROMs[edit]

@Jc3s5h: Multiple-emitter transistors can be used in ROMs [1], but I've no idea what the OP meant by "analog". Perhaps he considers any application of BJTs to be analog? SpinningSpark 17:06, 10 December 2015 (UTC)

For those who haven't seen it, this thread is about this revert of an edit by user:Phiarc. SpinningSpark 17:10, 10 December 2015 (UTC)

I've never heard of an analog ROM either. Jc3s5h (talk) 21:50, 10 December 2015 (UTC)

The technology was developed by Barrie Gilbert of Tektronix for the analog readout system of the 7000 series oscilloscopes. You can read about it here. The analog mask ROMs use an array of multi-emitter transistors. Data is stored in these ROMs in the number of emitters connected to the output. Similar technology was duplicated in the USSR to the best of my knowledge. However, since it is pretty niche I'm totally fine with it not being in the article. -- Phiarc (talk) 22:48, 10 December 2015 (UTC)

Need better picture of NPN/PNP symbols for infobox[edit]

Currently, there aren't very many clean images of electronic symbols available at wikimedia for use in the infobox. (Compare to the nice svg images in Resistor and Capacitor.) If anyone had any, or could produce any, that would be very much appreciated. Tpdwkouaa (talk) 23:13, 22 December 2015 (UTC)

Introduction misleading on Lilienfeld?[edit]

The introduction looks excellent in most respects, but I feel it is a little misleading on the subject of Lilienfeld's contribution. "...conceived...by Julius Lilienfeld, and...practically implemented by...Bardeen...Brattain, and...Shockley" makes it sound like Lilienfeld did all the creative work and BBS were just his laboratory assistants. Were Bardeen, Brattain, and Shockley even aware of Lilienfeld's work? The Nobel was given to BBS, but the intro makes it sound like Lilienfeld also shared in it. L didn't even build a prototype. I think the intro should credit BBS as the inventors, but say Lilienfeld had the idea for the field-effect tran sister before them. --ChetvornoTALK 20:39, 6 March 2016 (UTC) ChetvornoTALK 20:39, 6 March 2016 (UTC)

Yes, it's completely misleading and should be taken out. Lilienfeld's idea was a field-effect device, completely unrelated to the point-contact junction device that was actually the first transistor. Lilienfeld deserves a mention in this article, but he really was not part of the thread that led to the first transistor being made. SpinningSpark 22:45, 6 March 2016 (UTC)
Yes, misleadingly stated. Lilienfeld's invention did come up as a big block to broad patent coverage on the transistor; Shockley tried to make a FET, but couldn't make it work at that time, due to surface charge problems; then the other guys came along and made the bipolar work. The relationship here is important, but hard to state correctly in so few words. Dicklyon (talk) 04:10, 7 March 2016 (UTC)
When I was reading the article, I noticed the ambiguity over Lilienfeld and the Nobel Prize. I've gone and changed the wording to remove the ambiguity by making the winners' names explicit. There might be a better way to phrase it than I've done but it's an improvement. Also, don't forget our unofficial motto: "Be bold". Jason Quinn (talk) 21:10, 25 March 2016 (UTC)
