The @hackerfabindia demo day!!! I loved seeing everyone and how enthusiastic they were about the sputter, the tube furnace and the litho!

I got the chance to meet some fantastic people yesterday! I’ve included a time lapse of everyone!

Ever wondered how we turn silicon wafer into chips?
We did @hackerfabindia and are making a student built chip fab.

Come visit us for a lab open day as we demonstrate our systems at IITB on Wednesday 15th April, 2-5pm to learn more.

A sneak peek into our tube furnace build @hackerfabindia

The heating element has a coiled-coil structure inside the furnace to maximise resistance, maximising the heat radiated (I^2R)

[Rushat Dixit @rushat_dixit]

@lukecodez thank you so much! one key detail I missed was that our furnace costed ~30,000 INR (321 USD) and a commercial tube furnace of similar capabilities costs ~6 Lakhs INR (6428 USD)!

[Rushat Dixit @rushat_dixit]

The tube furnace has a consistent operating temperature of 1100 C with a thermal stability of +-2 C!

Look at how beautiful different thickness of silicon oxide looks!
Deep Violet / Burgundy : 219.6 nm
Golden : 167.9 nm
Royal Blue : 105.3 nm
Violet : 80.6 nm
(Predicted value)

Me and my friend @Abhineet_Avhad just made a tube furnace from scratch at HackerFab IITB!

All we needed was 50 meters of Kanthal A1, 18 kilos of refractory cement, 12 kilos of ceramic wool, 20 kilos of steel, a quartz tube, and some silicon wafers!

@hainbehen @Abhineet_Avhad yes definitely! dm me

[Aryamman Bhatia @aryamman_bhatia]

Rushat and Abhineet just built a tube furnace and oxidised our first Si wafer @hackerfabindia

The furnace reached 1100C with +-2C error - and it costed a fraction of what it would to buy it off the shelf.

They are UG freshers and did this all by themselves!
