2026-06-26 · transistors not touching claim
It's literally not touching the other fet, how can it be bonded, this is more likely just two different images put together

2026-06-26 · bonding method description
They don't bond the top transistors, they only bond a channel crystal lattice orientation then build the top transistors into that. As for the method of dielecric bonding the lattice, they said that's the secret and won't be disclosing it at this time
