I learned a bunch of stuff attending the ASGS Symposium at Salem Community College last week.

I learned a bunch about Quartz glass! AKA Fused Silica- its glass without any fluxes- just super pure silica! Its needed for production and one of the US symposium sponsors is using Chips act funds to be there (they are trying to triple their glassblowers in 10 years).

Quartz is so weird to work with- it sublimes (goes from solid to gas) and leaves behind vaporous quartz as white haze around the area worked. In a semiconductor environment you would use hydrogen fed torches and gloves with Hydrofluoric acid washes in between operations! The is like a hot laserbeam flame. wont ever boil, stops moving quickly and is almost impervious to thermal stress

Glass knowledge wasn't the only thing I picked up though- my body also picked up some I just discovered .Time to stay home :)

Bob Singer making a quartz device that his company makes for oil or gas testing. He uses a fresh clean graphite rod or another quartz rod as his tools to avoid impurities. Welding shades protect the eyes from the intense UV coming off the hot quartz,
filling in cuts in a quartz rod and using a quartz and graphite roller wheel to smooth them out. The challenge is to fill the cuts cleanly and without any bubbles. I could get it clean- but there were so many bubbles. In industry, rods like this would make big racks to hold hundreds of silicon wafers for production
The inside of a Wheeler diffusion pump that a presenter made in an an afternoon. This would then get sleeved inside another tube to make the pump. The glass flares and tubes in tubes create an extreme evaporative action that boosts high vacuum pumping speeds and help you reach even lower pressures.

    Never mind or "AI": Let's talk about the water needs of the industry.

    "Without secure access to large volumes of there are no , and without semiconductors there are no electronics. The emergency is a major driver of water stress both now and in the future. Can the tech sector cope?"

    #US Secy of #Commerce #GinaRaimondo co-led a discussion w/Costa Rica’s Min of Foreign #Trade ManuelTovar; Min of #Science, #Innovation, #Technology & #Telecoms PaulaBogantes; ViceChair of the #ExportImport Bank of #UnitedStates #JudithPryor; & Asst Secy of Commerce for #Export TheaKendler; as well as industry & other stakeholders about collaboration on #SupplyChain challenges, particularly the #semiconductor industry.

    During the roundtable, the Secy emphasized the impact that investments like the #CHIPS & #Science Act have had on revitalizing #semiconductor #manufacturing in the #UnitedStates & the opportunity for catalyzing private #investment in #CostaRica & the #Western Hemisphere. Secy Raimondo, Mins Tovar & Bogantes also heard from participants about opportunities across the semiconductor #ValueChain & the role of partners, like Costa Rica, in strengthening global semiconductor #SupplyChain resilience.

    There's a great throwaway line in 1992's Sneakers: Dan Aykroyd, playing a conspiracy-addled hacker/con-man, feverishly tells Sydney Poitier (ex-CIA spook) about a 1958 meeting between Eisenhower and aliens where he said, "look, give us your technology, and we'll give you all the cow lips you want."

    Crucially, the report lays out the role that the weakening of , the dismantling of tariffs and the strengthening of IP played in the history of the current moment. The failure to enforce antitrust law allowed for monopolization at every stage of the industry's supply-chain.
