Inside Seagate's Cleanroom

POLARIS 2500 in the background - what a machine!

[chrstianmom]

Does anyone know where i can get fallout wafers (the ones that get ruined during production in the US? i gotta friend that pays a hefty amount of money on these kind of wafers. broken, whole even the top or tail part of the ingot these can be high or low resitivity????? let me know there is big bucks to be made on silicon wafer fallout or unusable disregarded messed up wafers i have a buyer eager for the stuff that these major companys just toss away. one mans trash is another mans treasure

[lexichronicle2]

@chrstianmom I don't think they just chuck the wafers. They will recycle them into the new silicon because there's already money invested in purifying the material. If it's already gone through some processing, they will be able to clean the surfaces back to bare.

@lexichronicle2 I used to work for TI in a cleanroom, and they do just chuck the wafers, especially broken ones. The primary cost of chips is in the extreme processing, not the value of materials. The real reason you can't take wafers home (I asked) is because they're from other companies' products with trade secrets involved. Also, many fabs also make military weapon chips, and you can't let "christianmom" get those.

@fungicord chuck them into recycling bins. it's not going in the land fill is it, after all the purification that's already been done

[fungicord]

@lexichronicle2 Sometimes there's a reclamation process, and the wafers are crushed during this. I've heard the goal is to retrieve some of the exotic elements used during processing. The purity value of the silicon is completely lost after crushing because it needs to be fully heat-processed again to become a monolithic crystal of silicon ready for slicing into wafers. I imagine most companies will jump (or have jumped) on IBM's bandwagon: watch?v=ooMmwSqr9XY

[fungicord]

@lexichronicle2 Remember that a major goal during semiconductor manufacturing is to make the silicon impure (i.e. doping, ion implantation) to alter the silicon's properties toward either conductive or non-conductive to change how the silicon behaves. Add to that the thin metal layers (copper or aluminum) and the many chemical etches and depositions, and the overall purity is gone in a hurry.

@chrstianmom Wafers aren't cheap, priceless if they are partially processed. Companies keep a pretty good eye on them. Good luck.

seagate blows. i fucking hate you for making me lose a ton of information because of your shitty drives that fail after 2 months. FFFFFFFFFUUUUUUUUUUUUU...

[brainjourney]

Is this guy kidding?????? No SSD (flash fab) would handling a wafer with a vacuum wand. Too low tech.

He needs to visit an Intel flash fab before he brags about high tech.

Nice Polaris in the background :?)

So manufacturers interpret a gigabyte as 10^9 bytes whereas windows interprets it as 2^30, which is more technically correct. So to get from manufacturer specs to actual specs multiply by (10^9)/(2^30). Or for terabytes multiply by (10^12/2^40) etc. etc.

คิดถึงซีเกทจัง i'm have been working in seagate for 10 years.ohhhhhh

miss seagate!!! live in Norway not easy to find jobb. คิดถึงเพื่อนๆจังๆ

[mig189189189]

Awesome video!

[tytyblu]

@nasum69 Type "500000000000 bytes in gigabytes" into Google :)

[devildad1620]

I spent years in a wafer fab. I think this guy is reading a script and does not know what the ef he is talking about.

[wwwatbc]

Need to remove this ASAP

[bigharks]

bullshit seagate is a dump lol

[petesteg]

The read/write sensor of every hard drive is made this way. Just as important (maybe more so!) than the disk media.

[xtom1973]

i dont get what that is... it is no platter?

what has this to do with hard drives?

(sorry)
