With roots tracing back to the early 1990s, our expertise in semiconductor capital equipment began in Northern Ireland’s Semiconductor Research Centre. Aaron Moore, the founder, has extensive experience spanning decades, including a three-year tenure with a leading Japanese electron microscope manufacturer and nearly a decade with a U.S.-based CDSEM (Critical Dimension Scanning Electron Microscope) manufacturer.

Following the withdrawal of this U.S. company from the CDSEM market, WJA Electron was born to continue supporting the installed CDSEM systems. Over the years, our services expanded through a global network of experts, allowing us to provide support not only for Defect Review SEMs and CDSEM but also Dual Beam FIB, laboratory SEM/TEM, and specialized services such as Schottky emitter electron source refurbishment. More recently, with increasing demand for CDSEM support, we formed a joint venture with BOK-OPT in Singapore to better serve our clients across the globe.
