I'm a mechanical controls engineer, five years into semiconductor equipment. Four of them at ASML on the reticle stage of EUV lithography systems; now at Applied Materials on controls for inspection tools.
Mechanical Controls Engineer
Control systems for semiconductor inspection tooling — the machines that check what lithography just produced.
Senior Mechatronics Engineer — Reticle Stage, Design & Engineering
Four years on the reticle stage of EUV lithography systems: maintaining and improving the control architecture of the motion stage, and qualifying design changes on test rigs before they reached the field.
Graduate and undergraduate work — the rigs and models the professional work is built on.
Swing-up and stabilisation of a multi-degree-of-freedom inverted pendulum on hardware I built the driver for: bring the rod up from hanging, then hold it upright against whatever you do to it.
