A semiconductor manufacturing tool as a product, such as a deposition, etch, lithography, metrology, test or assembly tool, from customer roadmap alignment and technology requirements through concept and subsystem architecture, module development, control software and factory automation, prototype build, alpha and beta tools at customer sites and process qualification to production release, installation, installed base service and spare parts, upgrades and end of support, with export control compliance throughout.
Semiconductor equipment lifecycle: 13 stages and 20 gates, from Customer Roadmap & Technology Requirements to End of Support.
13 stages and 20 gates, 3 of the gates technical readiness reviews (TR). Each stop opens its stage; each sign opens its gate. Point at a stop or tab to it to read what the stage is for. What the codes mean

Working with lead chipmakers and their process roadmaps to learn which process steps, materials, wafer or panel formats, throughput and cost a future tool must support, and turning that into technology requirements, a market view and a programme proposal.
Customer roadmap commitment gateTechnology requirements baseline gate
Choosing how the tool will meet its requirements: the process module or chamber concept, the platform and wafer handling, the split into subsystems with their interfaces and error budgets, the control architecture, the safety concept and a cost of ownership model, with a business case for development.
System architecture freeze gateTR1, technical readiness reviewConcept and business case approval gate
Designing, simulating, building and testing the tool's modules and subsystems on test stands: process chambers, sources and optics, vacuum, gas and fluid delivery, wafer handling, power and RF delivery, thermal control and sensors, each against its specification and interface documents.
Building the control software that runs the tool: sequencing, recipes, interlocks, process control, alarms, the user interface and data collection, and the factory host interface to public SEMI standards such as SECS/GEM, the automated fab standards and equipment data acquisition, with equipment cybersecurity designed in.
Assembling the first complete tool in-house, integrating hardware and software, testing it against its requirements in the demonstration lab, running first process results on test wafers, and assessing safety and compliance before anything ships.
Prototype internal acceptance gateTR2, technical readiness reviewExport classification and licences in place gate
Installing a first tool at a lead customer or a joint development site and proving it works in a real fab, with engineering staff on site, joint process development, fast design changes and a shared record of issues.
Shipping tools built close to the production design to several customers to prove process performance, reliability, throughput and matching across tools and sites, under agreed evaluation criteria.
Beta shipment approval gateBeta performance demonstrated gateTR3, technical readiness review
The customer's qualification of the tool in its own process: process window, matching to the reference tool, defects and contamination, reliability and uptime against the customer's acceptance criteria, ending with release into the customer's process baseline and an agreed change notification arrangement.
Releasing the design to manufacturing: the bill of materials, drawings and build instructions, qualified suppliers, the factory acceptance test, export classification of the released configuration, service readiness, and the ramp of tool building to repeatable quality and cycle time.
Getting each tool into service at the customer: export screening and shipping, site preparation with the customer's facilities team, move-in, hook-up to utilities, start-up, the site acceptance test, process acceptance and the customer's final acceptance.

Keeping tools in the field productive for as long as customers run them: service agreements, preventive maintenance, field service and escalation, spare parts planning and logistics, uptime reporting, remote diagnostics with controlled access, and configuration tracking across the installed base.
Improving tools already in the field and extending the platform: performance and productivity upgrades, retrofit kits, field change orders for safety or reliability, software updates, derivatives for new applications, and requalification where a customer's process needs it.
Closing out a platform: end of sale, end of support notice, last-time buys of spares and obsolete components, transfer of support to refurbishment or other agreed providers where customers want it, the final support date and the archive of design and service records.
