Engineering Confidence for Legacy KLA Inspection & Metrology Systems
Engineering discipline, onsite field service, parts, refurbishment, training, and lifecycle planning for the problems OEM support no longer covers.
Engineering Support for Long-Lived Semiconductor Manufacturing Assets
Legacy semiconductor manufacturing systems often remain critical to production long after original support, parts availability, and platform knowledge have declined.
Keeping these systems operational requires more than replacement components. It requires technical understanding of the complete asset, including system configuration, subsystem interaction, motion, optics, electronics, software, utilities, process requirements, failure history, and obsolescence risk.
BTG Engineering evaluates the system and the customer's operational requirement before recommending a path forward. Depending on the condition and scope, that path may include field service, failure analysis, repair, refurbishment, parts and component solutions, reverse engineering, preventive maintenance, training, validation, or long-term lifecycle planning.
Our objective is to develop one coordinated technical solution that addresses the immediate challenge while improving the system's long-term reliability, supportability, and value.
Dedicated technical knowledge across legacy KLA inspection and metrology platforms, including system architecture, configurations, applications, common failure domains, and lifecycle requirements.
Engineering support across the complete operational life of the asset — from evaluation and installation through maintenance, repair, refurbishment, upgrades, training, and long-term support planning.
Documented evaluation, failure analysis, repair strategy, configuration control, subsystem validation, system verification, and customer acceptance through the BTG Engineering Validation Standard™.
Four Connected Capabilities
BTG Engineering brings together four connected capabilities that help customers evaluate, maintain, restore, and extend the useful life of legacy semiconductor manufacturing assets.
Legacy KLA System Support
Our flagship technical practice focuses on extending the useful life of legacy KLA inspection and metrology systems through platform expertise, engineering support, refurbishment, onsite service, parts, training, and lifecycle planning.
Technical Services & Parts
Onsite FSE support, preventive maintenance, installation, relocation, technical training, parts and component solutions, repair, reverse engineering, and planned lifecycle-support programs that help keep critical equipment operating.
Engineering & Operations Center
A purpose-built engineering environment for customer-owned equipment projects and factory-refurbishment programs — supporting engineering evaluation, repair, refurbishment, validation, and technical development.
BTG Engineering Validation Standard™
The disciplined framework BTG Engineering uses to evaluate, document, validate, and continuously improve technical decisions and customer outcomes.
Start With the Challenge. Build the Right Solution.
BTG Engineering is organized around the customer challenge, not around selling a predetermined service.
Customer Challenge
Understand the customer's technical, operational, equipment, or lifecycle requirement.
Technical Evaluation
Evaluate the system, application, condition, technical risk, customer objectives, and long-term requirements.
Internal Expertise + Strategic Partnerships
Apply BTG engineering, field-service, repair, refurbishment, parts, applications, and training capabilities while engaging trusted specialists when they improve the outcome.
Integrated Customer Solution
Deliver one coordinated technical solution rather than a collection of disconnected services.
Long-Term Lifecycle Support
Continue supporting the asset through preventive maintenance, field service, parts, training, refurbishment, engineering development, and lifecycle planning.
Building Technical Capability With Purpose
Legacy KLA inspection and metrology systems are BTG Engineering's flagship technical practice.
Our goal is not to claim expertise across every semiconductor technology. It is to build meaningful technical depth where we can deliver measurable customer value, then expand that capability deliberately over time.
BTG continues making disciplined investments in engineering talent, facility infrastructure, technical documentation, specialized tooling, training, and strategic technical partnerships to expand the technologies, platforms, and solutions we provide.
As we strengthen and master our Legacy KLA practice, the same disciplined model can support additional technical practices and legacy semiconductor platforms in the future.
How We Build Technical Capability That Holds
These five principles define how BTG Engineering approaches every engagement — from initial evaluation through long-term lifecycle support.
Technical Expertise
BTG Engineering's technical team brings decades of hands-on semiconductor equipment experience across field service, applications, engineering, repair, systems integration, and commercial operations. This depth is not theoretical — it comes from engineers who have installed, maintained, repaired, and rebuilt these systems in production environments. Platform-specific expertise means fewer escalations, faster root-cause identification, and more accurate assessments of what a system actually needs to operate reliably.
Engineering Discipline
Every technical engagement at BTG Engineering begins with structured evaluation, not assumptions. We document the system condition, define the requirements, validate the approach, and track outcomes — not because we're required to, but because disciplined execution produces better results. This methodology creates consistency across every customer engagement and gives customers a documented record they can reference and rely on long after the work is done.
Continuous Technical Development
The knowledge gained on each engagement — repair methodologies, component behavior, system interaction, failure modes, and application insights — is captured, validated, and integrated into BTG Engineering's technical baseline. This means each subsequent engagement benefits from what came before. Over time, this compounds into a technical depth that cannot be replicated by intermittent or reactive service providers working without documented institutional knowledge.
Strategic Technical Partnerships
No single organization covers every technical domain at the depth a given challenge may require. BTG Engineering identifies and develops strategic partnerships with specialists who extend our technical reach without compromising quality or accountability. Partners are selected for demonstrated expertise and integrated into the BTG engagement model — customers receive one coordinated solution, not a fragmented handoff between vendors who don't share information.
Lifecycle Thinking
Legacy semiconductor equipment does not fail on a schedule, but it does age on one. BTG Engineering evaluates not just the immediate challenge but the full operational trajectory of the asset — condition, obsolescence risk, supportability, upgrade potential, and long-term cost of operation. This perspective allows customers to make informed decisions about investment, maintenance, refurbishment, and end-of-life planning rather than reacting to each failure in isolation.
