Anybody?

content: Or they bought a collection of dies from the Keysight fire sale in California. It seems nearly everything that was in the building is for sale even though a lot of it should have been crushed.

content: Those are interesting, but what on earth would someone do with one? If they were a buck or two I might buy one as a curiosity but hunreds? Who has the equipment to utilize a bare die?

content: They're not delusional. If you don't know the price, list at an upper bound or-best-offer and apply your favorite "stopping problem" strategy (e.g. reject first offer, accept first subsequent offer that exceeds it).

content: Quote from: jjoonathan on March 11, 2018, 11:00:20 pmI suspect he knows the list price but not the resale value. Anyone who normally buys these will not be buying them on ebay. You often see a similar thing with FPGAs - people look up the price on Digikey and get over-excited.

content: Then I suppose I should figure out who the local liquidators are in my neck of the woods (RTP, North Carolina). We've got a bit of semiconductor R&D presence -- with the Hittite merger and the Qorvo layoffs, maybe something will show up.

content: Quote from: Gandalf_Sr on March 12, 2018, 09:43:05 amYou are correct, of course. I just wanted to say Agilent die! figuring it would get lots of views.Does anyone know whether Agilent did fab work for third parties? I'm still wondering if these were used in their test gear...

content: Quote from: Gandalf_Sr on March 12, 2018, 09:43:05 ami thought only non native could misinterpret. anyway another suggestion from non native could be Agilent dye or Agilent diy. but more precisely i think is Agilent hybrid.

content: I am being deliberately pedantic but the plural of die is dice.Either way, it's interesting that these dice have found their way onto eBay but the sellers are quixotic if they think they will get anywhere near their asking price.

content: Quote from: Gandalf_Sr on March 12, 2018, 10:50:51 amIt's hard to say without knowing what they go to; and that's the problem for the seller. If you knew that one of those might make it possible to fix a $30K piece of gear that's currently being used as a doorstop, then it would be worth it.

content: Way back when the company I work for used to have its own fab, it was not uncommon to have rejected wafers out and about. Somewhere I have a couple wafers with memory and what is equivalent to a north-bridge on them. I'd pony up $10 bucks just to show them to kids.

According to Wikipedia dice, dies and die are all common plural forms."plural dies : any of various tools or devices for imparting a desired shape, form, or finish to a material or for impressing an object or material: such asa (1) : the larger of a pair of cutting or shaping tools that when moved toward each other produce a desired form in or impress a desired device on an object by pressure or by a blow(2) : a device composed of a pair of such toolsb : a hollow internally threaded screw-cutting tool used for forming screw threadsc : a mold into which molten metal or other material is forcedd : a perforated block through which metal or plastic is drawn or extruded for shaping""There are three commonly used plural forms: dice, dies, and die."

content: It looks like an impedance matching line, the T shaped side would be bonded to the die and the wider, probably 50 ohm side would go on to other 50 ohm devices.
