Linde is huge. They can produce and offer all gases in all available purity classes.

Is there some reason you'd want gasses in a lower purity class? (Well, it's cheaper.)

The only reason is cost. If you don’t need the purity then save the money.

Unless things have changed a lot since I fled semiconductor manufacturing, you would still need silane tanks at least. I’m as surprised as you that they don’t have buffer tanks.

Why did you use the term "fled"? Any interesting story? From the outside, I would love to participate in semiconductor manufacturing.

I left the industry because it is soul crushing for anyone who wants to try new ideas.

I also had a pager strapped to me 24/7/365. Finding a US backup for a UI developed in an obscure language owned by a Japanese IT company proved to be quite challenging. I bet they're still using it to this day and just managing it from Korea now. The risk of rewriting or refactoring some of this stuff is measured in 10-11 figures.

GT:NH has “easy mode” enabled in some regards - it won’t finish the craft but it WILL wait for power (actually keep trying) - so if you fix the power problems you can finish and not lose the mats. May or may not apply to multi blocks.

Multiblocks power fail and void, but then your machine shuts down until you restart it. This is much better than suggested above, where you'd void over and over, but it can still utterly mess up a large craft being orchestrated thru AE2, which is still waiting forever for he failed craft to submit a part back into the system.

Yeah people talk about GT:NH being this super tedious hard pack, but it actually has tons and tons of quality of life fixes to the various mods that make it up - and voiding materials is something that is almost nearly gone (iirc very early on a single block, even steam, losing power would lose the materials, which made learning early steam (especially the alloy smelter) really painful).

I didn't finish GT:NH but if I ever set aside enough time to play a GregTech build again, GTNH is on the very short list.

It's extremely well polished, and I've played enough that it's nearly impossible for me to play Minecraft without playing GT:NH, as the moment I start a vanilla play through I find myself adding mods to make it easier and then I realize I'm just rebuilding GT:NH - badly.

It really is about the journey; GT:NH isn't played to be won - instead, the win condition is continually moved out so you can keep playing.

It might be more convenient to purchase pre-blended mixes for many applications. For example 90% argon 10% isobutane. In welding this would be "impure" but for ionization counting it's exactly what you want.

seems like what is often downplayed or silent on American media is the cultural mismatch between TSMC taiwanese engineers and their american counterparts so it always comes to those out of the loop as a bit of a surprise but from what I've read from individual Taiwanese workers and their feedback its clear that there is significant regret from one side. and it doesn't seem to limited to just TSMC but another large co…

Why do you think it’s cultural and not a skill issue? For example Tim Cook said they produce in China not because of costs but skills https://www.benzinga.com/markets/25/04/44783543/when-tim-coo...

This was apparently a Linde installation custom built for TSMC in Arizona.[1] Nitrogen, oxygen, and argon are extracted from air on-site and purified. That's Linde's primary business; liquefying and distilling air. This isn't some little local company or a company operating outside their area of expertise. Those gases are storeable, so it's surprising there wasn't enough tank capacity to deal with outages. The site p…

Silane, with the chemical formula \(SiH_{4}\), is a highly flammable and toxic inorganic gas used in industries like semiconductors, construction, and dentistry. It serves as a crucial precursor for creating high-purity silicon and is a versatile coupling agent that enhances adhesion between materials like glass and polymers. Its reactivity also allows it to be used in coatings, sealants, and various chemical syntheses.

Chemical Formula: \(SiH_{4}\) Appearance: A colorless gas with a repulsive odor Flammability: Highly flammable and pyrophoric, meaning it can ignite spontaneously in air Toxicity: Very toxic by inhalation and a strong irritant to the skin, eyes, and mucous membranes

GT:NH is a very interesting software project in itself, a long-living open source environment with devs maintaining forks of a lot of mods included in the pack and backporting features and fixes to 1.7.10, custom tools for development/planning and a lot of spreadsheets with data

The semiconductor manufacturing process is so ridiculously cool that they have to make the working conditions terrible to keep the plant from being flooded with junior engineers. I worked in ion implant, which means I was responsible for honest-to-god particle accelerators working right. But you pay for the cool factor in sweat. Pager duty isn’t a thing you take turns with. It’s your duty to carry a pager, always, from the day you sign on until the day you leave. And you will get paged. A lot. At all hours. Some of those pages will require you to go in, but you work so many hours at the plant that you’re probably already there. Did you know that “exempt” means “exempt from the 40 hour work week?” You probably have to attend at least one passdown meeting a day. Those are at 6, and whether that’s a.m. or p.m., it means you’re working a long day. The fab needs weekend coverage too, so every fifth or sixth week, you go in and work straight through, 12 days.

And then there’s the software. Part of my job was entering numbers into a system that had been designed to make it hard to enter numbers in it. This was so that you wouldn’t change them too often. But we did. A big part of the job was data analysis, but instead of actual access, certain data was only available as server rendered PNGs. Small ones.

I could go on, but I think that’s enough.
