A long time ago in this thread there was a goon with very good stories about dealing with these sort of gasses and, I believe, an earthquake prone city that decided to build underground pipes for the gasses? Or something like that?

Methylethylaldehyde posted:Can't some of the gas byproducts of half the hellbrew chemicals they use poison processes at like the parts per billion level? There are no gas byproducts in the system I described. Everything is contained until it gets to the tool then used and then it has an appropriate exhaust (acid, solvent, etc.). But we aren't bleeding edge so defects aren't measured on the ppb level. Only the DI water used (and chemical assays) have requirements down to ppb. And all the chemicals are industry standard. I'm curious the hellbrew chemicals you are thinking of.

He's probably referring to one of the mixes that engineers pull from satan's cookbook that are straight 4's on a HAZCOM placard and have no known neutralizers other than time and distance. In a fab, you'll only deal with lecture bottles of those kind of things from that one chemical engineer (you know which one it is) and not anything that's plumbed through the facility.

TotalLossBrain posted:In the lab I'm at, all the eyewash stations have little pucks of calcium glucanate or whatever you're supposed to have on hand for HF incidents Yes, there are tubes of calcium glycinate next to the eyewashes and emergency showers near the HF/BOE benches. HF doesn't burn, but will attack calcium (ie. your bones). Sulfuric acid burns are more obvious.

ILL Machina posted:Successful emergency ferry evacuation in Canada due to fire I wonder what an emergency evacuation of MS Estonia would have looked like if there had been a fire in calm weather instead of the front falling off in a storm. A lot of the people were sloshed, how do you get hundreds of drunks to put on a lifevest correctly and get into a barge in an orderly fashion? And make them leave their tax free alcohols on the ship?

I'm curious the hellbrew chemicals you are thinking of. I more meant if any one of the many caustic, corrosive, or gaseous horrible chemicals manages to leak, the resulting fine aroma of hellbrew byproducts can do real bad poo poo to in process wafers if it somehow finds a way in. I know some parts of the process are sensitive enough to basically everything that even tiny amounts of contaminants can cause a batch of wafers to be scrapped and made into decorations vs. continuing the process on them. Like that batch of flash that had to get tossed due to contaminated feedstock. Now I'm wondering how many layers of redundant systems are in place to keep 'whoops, I spilled some MEK near the lithography unit' from actually causing a batch of wafers to fail due to contaminants.

I know some parts of the process are sensitive enough to basically everything that even tiny amounts of contaminants can cause a batch of wafers to be scrapped and made into decorations vs. continuing the process on them. Like that batch of flash that had to get tossed due to contaminated feedstock. For what you're talking about, transition metals do that just fine. PPT-PPB amounts of gold can wreck a batch of wafers just fine. Gold-handling processes get basically quarantined from everything else. The biggest contamination concerns are boring stuff like chloride, gold, copper, human juice, etc. Either through volume or how much they wreck an in-process wafer. MEK you're not gonna see outside of an enclosed system inside a fab. Smells too awful for starters. As for the doom chemistry, CVD/diffusion gases make HF look pleasant. Stuff like silanes to deposit Si or other stuff. Some of it gets made on site by who I think is a dark wizard since it's easier than permitting the shipment. Those systems are totally enclosed with kickass exhaust systems. A good chunk of my job is analyzing/identifying dusty exhaust buildup so it can be safely cleaned. Usually it's just sand though.

Like that batch of flash that had to get tossed due to contaminated feedstock. Back-end processes (once the metal connects are deposited on the wafers) are segregated from the tools that do the front-end processing (making the transistors). Exotic metals (gold, etc.) are usually done in a separate building.
