反応性イオンエッチングに向けた予備実験❗️ R32ガスを少量注入しつつ、DCマグネトロンスパッタリングによるプラズマ処理をやってみてる ガラスの表面改質はできてそうだけど、エッチングは難しそう…RFプラズマじゃないとダメなのかなー🐈

リソグラフィー工程ある程度安定して出せるようになってきた❗️ 現状安定して出せるリソ工程の最小線幅は20-30μmぐらい・・・ より高画素のDLP式プロジェクターと高性能な露光用レンズがあればもっと微細にできそうではあるけど お手軽じゃなくなりそうなので露光機はとりあえず完成とす❗️

I am extraordinarily disappointed with AWS / customer service who has been both difficult to reach and largely script based for something that requires intervention due to the bootstrapping issue. If anyone has any tips on how to expedite this process I would be very grateful!

I have been locked out of my https://t.co/uSHwYdq3dL accounts for the past week due to an expired credit card knocking out my DNS served with AWS route 53. I can't log into my AWS account to fix it since with DNS gone I can't receive a sign in code, or any other email for that
