<CIA-67> homecmos r117 | wiki/Vendors.wiki | Edited wiki page Vendors through web user interface.
<B0101> Azonenberg: I have updated the semiconductor supplies page. I have added a vendor but it probably ship to singapore only.
<B0101> I will update when i get more data
<azonenberg> Well... it's been a while but i think i will have time this weekend to get to a run i've wanted to do for a long time
<azonenberg> namely, testing the Cr etch process
<azonenberg> If all goes well i will be doing a first try of KOH etching through metal tonight
<azonenberg> that is not cheap
<azonenberg> Gonna see if my school's library has a copy i can borrow
<B0101> Azonenberg: where do i get tantalum film?
<azonenberg> B0101: Tantalumfilm != tantalum film
<azonenberg> it's the trade name of a solution sold by Emulsitone
<azonenberg> which actually forms a film of tantalum *oxide*
<azonenberg> It's 16% by weight tantalum chloride in ethanol
<azonenberg> And i dont recommend anyone go out and buy it until i finish this run of experiments
<azonenberg> it may well turn out that there's a much better and cheaper way of doing the same thing
<azonenberg> i'm hoping that an evaporated Cu+Cr hardmask will prove suitable for at least shallow etches
<B0101> Azonenberg: Is the change in the wiki OK?
<lekernel> azonenberg, yeah welcome to the wonderful world of academic publishing ...
<azonenberg> B0101: yeah, its fine
<azonenberg> you dont need to ask my approval for adding new sources lol
<azonenberg> lekernel: yeah, i've crossed paths with them before
<B0101> Azonenberg: well, these wafers are pretty cheap - 10 SGD
<azonenberg> I have no idea what that comes out to in USD, and for what size?
<azonenberg> MTI sells to US customers, at least, for around $39 per 4-inch and $29 per 2-inch
<azonenberg> last time i checked
<lekernel> someone should pirate all such books (and I¬¬¬ papers) and put them on bittorrent :-)
<azonenberg> I see no reason to ever get 4-inchers since i'm taking so many months to use up the 2s i have
<azonenberg> lekernel: Lol, the only reason i am not going through extreme lengths to get IEEE papers is that my school subscribes to them
<azonenberg> when i leave, though, i expect that will change
<B0101> Azonenberg: USD 8.21 at 4 inch (just called them)
<azonenberg> B0101: o_O
<azonenberg> in units of one?>
<azonenberg> or with massive min orders
<B0101> yup
<B0101> units of one
<azonenberg> wow, i may have to check those guys out
<azonenberg> this is for test grade? prime?
<azonenberg> not that i really need prime for most of my work
<azonenberg> but i'd rather not be using coinroll
<azonenberg> well i gotta get going, prof needs me to proctor an exam at noon and i have some errands to run beforehand
<B0101> ok, ttyl
<adc_> all i want for christmas is a p3x ...
<lekernel> I wonder how much this toy costs ...
