| CIA-67 | homecmos r117 | wiki/Vendors.wiki | Edited wiki page Vendors through web user interface. | 11:34 |
|---|---|---|
| B0101 | Azonenberg: I have updated the semiconductor supplies page. I have added a vendor but it probably ship to singapore only. | 11:35 |
| B0101 | I will update when i get more data | 11:36 |
| 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 | 13:22 |
| azonenberg | namely, testing the Cr etch process | 13:22 |
| azonenberg | If all goes well i will be doing a first try of KOH etching through metal tonight | 13:24 |
| azonenberg | o_O http://www.amazon.com/gp/search?index=books&linkCode=qs&keywords=0849336236 | 13:27 |
| azonenberg | that is not cheap | 13:27 |
| azonenberg | Gonna see if my school's library has a copy i can borrow | 13:30 |
| B0101 | Azonenberg: where do i get tantalum film? | 13:31 |
| azonenberg | B0101: Tantalumfilm != tantalum film | 13:31 |
| azonenberg | it's the trade name of a solution sold by Emulsitone | 13:31 |
| azonenberg | which actually forms a film of tantalum *oxide* | 13:32 |
| azonenberg | It's 16% by weight tantalum chloride in ethanol | 13:32 |
| azonenberg | And i dont recommend anyone go out and buy it until i finish this run of experiments | 13:33 |
| azonenberg | it may well turn out that there's a much better and cheaper way of doing the same thing | 13:33 |
| azonenberg | i'm hoping that an evaporated Cu+Cr hardmask will prove suitable for at least shallow etches | 13:33 |
| B0101 | Azonenberg: Is the change in the wiki OK? | 13:35 |
| lekernel | azonenberg, yeah welcome to the wonderful world of academic publishing ... | 13:35 |
| azonenberg | B0101: yeah, its fine | 13:35 |
| azonenberg | you dont need to ask my approval for adding new sources lol | 13:35 |
| azonenberg | lekernel: yeah, i've crossed paths with them before | 13:35 |
| B0101 | Azonenberg: well, these wafers are pretty cheap - 10 SGD | 13:36 |
| azonenberg | I have no idea what that comes out to in USD, and for what size? | 13:36 |
| azonenberg | MTI sells to US customers, at least, for around $39 per 4-inch and $29 per 2-inch | 13:36 |
| azonenberg | last time i checked | 13:37 |
| lekernel | someone should pirate all such books (and I¬¬¬ papers) and put them on bittorrent :-) | 13:37 |
| azonenberg | I see no reason to ever get 4-inchers since i'm taking so many months to use up the 2s i have | 13:37 |
| azonenberg | lekernel: Lol, the only reason i am not going through extreme lengths to get IEEE papers is that my school subscribes to them | 13:37 |
| azonenberg | when i leave, though, i expect that will change | 13:37 |
| B0101 | Azonenberg: USD 8.21 at 4 inch (just called them) | 13:43 |
| azonenberg | B0101: o_O | 13:43 |
| azonenberg | in units of one?> | 13:43 |
| azonenberg | or with massive min orders | 13:43 |
| B0101 | yup | 13:43 |
| B0101 | units of one | 13:43 |
| azonenberg | wow, i may have to check those guys out | 13:43 |
| azonenberg | this is for test grade? prime? | 13:43 |
| azonenberg | not that i really need prime for most of my work | 13:44 |
| azonenberg | but i'd rather not be using coinroll | 13:44 |
| azonenberg | well i gotta get going, prof needs me to proctor an exam at noon and i have some errands to run beforehand | 13:45 |
| B0101 | ok, ttyl | 13:46 |
| adc_ | all i want for christmas is a p3x ... | 18:10 |
| adc_ | http://www.dcgsystems.com/product.p3x.html | 18:10 |
| lekernel | I wonder how much this toy costs ... | 22:08 |
