Semiconductor equipment subsystem makers Ichor and Ultra Clean are the deeper edge in AI capex, since subsystems tend to outperform when the wafer fab equipment cycle expands.

Ichor is a $1.9B pure-play gas and chemical delivery supplier and a high-beta play, while Ultra Clean, at $3.3B with services, is more stable but pulls the same lever. x.comÂ
