Why it matters. Every modern chip — in your phone, in AI data centers, in defense systems — is a stack of hundreds of films just a few atoms thick. Each generation of chip forces a switch to new materials because the old ones physically stop working. Finding the replacement today takes a specialist months of slow, fragile physics simulations, one material at a time — and a wrong pick can blow a multi-year, multi-billion-dollar fab bet.

How densitygen helps. Type a plain-English requirement (“a leak-proof insulator for a 2nm transistor that survives a 1000°C bake”) and get a ranked shortlist of real candidate materials in seconds, pulled from the public Materials Project database, scored against the spec, with the unavoidable trade-offs on one chart. An AI agent does the tedious querying, filtering, and ranking; the engineer makes the call; the expensive simulations are saved for just the final two or three finalists. Months → an afternoon.

Who it’s for. Computational materials scientists and process engineers at semiconductor fabs (Intel, TSMC, Samsung), defense/aerospace R&D, and the precursor-chemical suppliers (Merck, Entegris, Air Liquide) whose multi-million-dollar bets ride on picking the right material.
