Semiconductor Equipment Power Supplies

Delivering sub-millivolt ripple on measurement rails, specified at a defined bandwidth, preventing image artifacts and measurement error in e-beam, optical, and metrology signal chains.

Providing isolated multi-rail distribution for chamber electronics, RF sources, motion controllers, and computing platforms, eliminating crosstalk between high-voltage switching and femtoampere-level detector circuits.

Engineering SEMI F47 sag ride-through into the input and hold-up stages, preventing tool trips that scrap wafers in process and force requalification.

Defining specifications, compliance pathways, and schedules before commitment through transparent NRE structures covering rail-by-rail noise budgets, in-enclosure thermal characterization, and SEMI F47 test planning.

Ensuring the supply qualified during tool acceptance matches production units identically through configuration control and PCN discipline.

Providing advance notification of changes affecting form, fit, function, or compliance across multi-year capital-equipment lifecycles through proactive obsolescence monitoring.

Horizon PSS takes ownership of compliance documentation and qualification testing:

Verifying SEMI F47 ride-through against the sag profile, delivering the test evidence your equipment needs to pass fab acceptance without late-stage redesign.

Supporting your equipment-level SEMI S2 assessment with documentation of the power subsystem's protective bonding, fault behavior, and energy-hazard controls.

Passing conducted and radiated emissions and immunity testing through architecture-level filtering, isolation, and grounding, addressing IEC 61000-6-2/-4 and EN 61326.

Meeting EN 60204-1 and UL 508 requirements for spacing, protective bonding, and emergency-stop integration, with CE technical-file inputs for the power subsystem.

Providing regulated high-voltage and RF power for deposition, etch, and CVD subsystems with controlled ramp, arc-handling behavior, and low coupling into adjacent sensitive rails.

Delivering ultra-low-noise power for metrology and inspection platforms where ripple on source and detector rails degrades resolution and repeatability at nanometer scale.

Supplying independently controlled DC voltages for ion-optic and beam systems in implantation and e-beam tools, where bias ripple directly degrades signal-to-noise.

Engineering transient-tolerant power for wafer-handling robotics and stage motion, maintaining regulation through rapid acceleration events without servo faults.

Delivering fanless and conduction-cooled architectures with low-outgassing materials for cleanroom and vacuum-adjacent installation, eliminating particle generation from moving parts.

Supporting procurement evaluation with SEMI F47 ride-through reports, ripple and noise data referenced to measurement bandwidth, EMC pre-compliance results, thermal and derating analysis, outgassing declarations for cleanroom class, and supply-chain qualification.

SEMI F47 and EMC compliance is owned at architecture level, not handed to you as a qualification burden.

Engineering depth covers measurement-grade noise budgeting, high-voltage and RF isolation, and cleanroom thermal design.

Production capability and design documentation are maintained across your capital-equipment lifecycle.

Custom design delivers fab-acceptance certainty and eliminates wafer-scrap and requalification costs.
