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>
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
<
adc_>
all i want for christmas is a p3x ...
<
lekernel>
I wonder how much this toy costs ...
