AMAT

What they do

The biggest U.S. chip-equipment company. They own 9% of BESI (the hybrid-bonder monopoly) and partner with them on the integrated 'Kinex' system. You're not just buying equipment — you're buying optionality on the BESI relationship and leadership in the next inflection (Gate-All-Around transistors, HBM, 3D-DRAM).
