Semiconductor fabs demand higher output, tighter process windows, and equipment that performs reliably around the clock. OEMs must introduce new capabilities quickly while maintaining precision, stability, and SEMI standards compliance. Equipment engineering teams manage complex interactions between mechanical structures, embedded controllers, motion systems, and software while improving KPIs such as throughput, OEE, and uptime.
Quest Global partners with OEMs from concept through qualification and field maturity, focusing on first-time-right engineering that supports stable production. Mechanical, embedded, and controls engineering is combined with digital capabilities such as model-based validation, test automation, and hardware–software integration verification through global engineering labs.
Challenges we solve
OEMs must shorten development cycles while managing increasing complexity across mechanical design, embedded systems, and control software, all while maintaining high equipment uptime. Tight schedules and limited test capacity raise the risk of late-stage issues, making early and disciplined verification critical. SEMI standards, including GEM and EDA, add further effort across subsystems and directly impact Factory Acceptance outcomes across global fab deployments. Equipment lifecycles spanning 25 to 40 years introduce challenges related to upgrades, obsolescence, and end-of-life planning. Quest Global addresses these needs through integrated engineering, structured validation, and sustenance services that support first-pass Factory Acceptance and long-term operational reliability, even when specialized skills are difficult to scale.
Focus areas
Software controls tool behavior and orchestrates interactions across subsystems involved in wafer processing. Our engineering spans the full stack, including firmware, middleware, device drivers, and real-time control software, with the development of equipment control frameworks and architectures designed for scalability, reliability, and long-term maintainability, validated through hardware-in-the-loop setups. The focus remains on software that executes and monitors process recipes with deterministic behavior under continuous fab workloads, supported by structured testing and update readiness.
Mechanical systems influence wafer stability, motion accuracy, and long-term serviceability. Our teams support full mechanical design and development using leading CAD platforms and advanced analysis methods such as vibration, thermal, and tolerance modeling. Engineering work strengthens precision, manufacturability, and cost efficiency, supported by validation under representative fab conditions. Sustenance support enables faster enhancements and reliable operation throughout the equipment lifecycle.
Automation frameworks govern wafer movement, process sequencing, and device coordination, and they must improve throughput, yield, and efficiency under continuous fab operation. We design and sustain automation frameworks using next-generation architectures and modern technology stacks that support precision wafer handling, complex processing flows, and improved operator experience, while remaining aligned with SEMI standards and human interface requirements. Dedicated engineering support helps OEM teams evolve automation performance faster and reduce risk during fab qualification.
Modern fabs require faster integration of equipment with MES and factory automation systems, making host connectivity and strict SEMI GEM and EDA compliance essential. We design and validate connectivity solutions that support evolving data and interface requirements, using host simulation to test both standard and fab-specific scenarios before deployment. Solutions proven across multiple equipment types help OEMs shorten factory acceptance timelines and achieve predictable integration outcomes across global fabs.
