Service contracts for research cleanrooms and pilot lines

Why a service contract

A service contract on semiconductor equipment does two things for a lab manager. It turns unpredictable repair bills into a fixed annual cost that can be planned in a budget. And it puts the tools on a schedule, so maintenance stops depending on whether someone remembers to book it.

For a university cleanroom with a handful of technicians and dozens of users, a contract also brings in engineering capacity that would be hard to hire for one or two platforms. For a pilot line, it means a known route to help when a tool in the process flow goes down, with the tool's history already on file.

What a contract covers

Each contract is written per tool, so different tools can have different levels of cover. A typical scope includes:

• Preventive maintenance visits at intervals set for each tool
• Calibration of flow, pressure, temperature, RF and exposure items on an agreed cycle
• Repair labour for faults on covered tools, on the terms written into the contract
• Remote support by phone, video and supervised remote session for your staff
• A spares package, optional: critical parts for your tools sourced up front and kept at your site
• An annual review of each tool's condition, its spares risk and any upgrades worth planning

What is not covered is written down too: typically damage from misuse, process kits and consumables you buy yourself, facility failures outside the tool, and upgrades.

How we scope and price it

We start with your tool list, the service history you have and the problems you see today. From that we propose which tools to cover and at which level. Not every tool needs a contract: a spin coater used twice a week may be better served per visit, while an etcher that half your users depend on probably is not.

Every covered tool gets a baseline inspection before the contract starts. That stops either side from guessing about condition and shows which spares are worth keeping on site. A tool that fails baseline is brought into specification first, under a separate quote.

The annual price depends on the number and type of tools, their baseline condition, the number of planned visits, the repair labour included and whether a spares package is part of it. We quote it per tool, so you can see what each tool costs to keep running and decide on cover tool by tool.

When a covered tool fails

A failure on a covered tool starts with a call or email to your contract contact. The first step is usually remote support: an engineer works through the fault with your staff by phone or video, using the baseline and visit reports already on file. If the tool needs on-site work, we give you a visit date at that point, based on the diagnosis, where your site is and what parts are needed. The contract states how repair labour and travel are charged, so the only open question when a tool goes down is the part.

How quickly a tool comes back depends heavily on whether the failed part is already on your shelf. That is why the baseline and the spares list matter more than any promise about visit times.

What you provide

• A named contact on your side who knows the tools and can book visits
• Access to the tools, facilities and your site safety procedures
• Fault and usage logs where the tools keep them
• Notice of process changes, such as a new gas or a new material in a chamber, which may change the maintenance plan

Results and documentation

Every visit produces a written report and every calibration a record with as-found and as-left values. Over a year these build into a full history for each tool, which helps when you plan upgrades, move a tool or sell it. At the annual review we go through each tool's condition with you and flag anything that will need budget in the coming years, such as a control system retrofit on a controller that is running out of spare boards.
