Bought Ed's book after watching this and am very glad I did - IMO a must-read for anybody, let alone those interested in technology and manufacturing. If only they'd taught us this kind of history in school ;) Thanks for the interview and great book
I loved this interview Matt. Thanks to both you and Ed. So interesting, and presented so well by both of you. Amazing how actually complex and even tenuous the supply chain is. Ed's research and knowledge are rich, and remarkable for someone who isn't specifically part of the industry. His passion for, and style of telling the story make me think of Tracy Kidder's "The Soul of a New Machine". I think I will need to put "Material World" on the stack that is my bedside table.
Thanks! Yes I read it and loved it. Was happily surprised when Ed was willing to do an interview!
This interview was super interesting! Waiting for next interview matt.
You are doing a great job in vulgarizing semiconductor technology. It would be very nice if you do a video on what it takes to setup a minimalistic fab for prototyping in terms of infrastructure, equipment and costs at a university lab or startup.
I could do a video on what other people have done. Search for Jeri Ellsworth, Sam Zeloof and 'Projects in Flight'
Very interesting interview!
thanks Timon!
Up till this year in Western Australia the chemical grade silicon plant was consuming 250,000 tonnes of chipped prime native jarrah timber per year harvested mostly from state forests. This wood chip was used as it is relatively clean carbon source , its roles was simply to support the melt and help degassing. Note these were not small trees these were pretty much fully mature large native trees being cleared from native forest. People just don't take these sorts of environmental cost into account when looking at silicon. Worse still this process only got them to chemical grade silicon which is a universe away from polysilicon.
The paper I linked in the description is a good read
Love the effort and the passion you have for this world Matt. Thanks, from a highly inquisitive nerd
What a great interview. I loved the content. Learned a lot about an industry I've been in since 1996.
I'd wager the silicon supplychain is probably a bigger peace keeper than anything else in terms of politics
yep!
