Where Lithography Fits in Front-End Wafer Fabrication
A lithography machine does not complete the whole photolithography process by itself. Track systems prepare and develop the resist, the exposure system defines the pattern, and metrology and inspection equipment confirms the result.
The patterned resist then guides processes such as etching or ion implantation. Thin-film deposition, thermal processing and CMP prepare or restore the layers used in the next manufacturing cycle.
The exact sequence varies by device, process layer and fab integration. Not every wafer layer uses every equipment category shown here.

Used Lithography Equipment Can Support Replacement, Expansion and Legacy Platforms
The value of used equipment is not limited to a lower purchase price. It can help buyers continue using proven production platforms, replace a failed machine, expand a mature-node line or obtain discontinued systems and spare parts.
This is especially relevant when an existing fab wants to preserve process continuity, operator familiarity and installed-line compatibility rather than change to an entirely different platform.
Discontinued Equipment and Spare Parts
Continue evaluating equipment families, replacement systems and components that may no longer be available through normal new-equipment channels.
Lower Capital Commitment
Consider a suitable mature-node or specialty platform with lower capital commitment while still reviewing the actual machine and delivery scope.
Continuity With an Existing Line
A familiar machine family may reduce changes to the process, operator training, interfaces and installed production environment.
Replacement and Technical Review
Machine photos, fault information and part labels can support replacement evaluation, spare-parts discussion and post-delivery issue review.
Understanding Lithography Machine Types and Exposure Technologies
Equipment architecture and exposure technology answer two different questions. A wafer stepper, lithography scanner or mask aligner describes how the pattern is exposed; i-line, KrF, ArF or EUV describes the light source and technology generation used by the semiconductor exposure system.
You do not need to determine the exact platform before contacting us. A model, photo, wafer size or basic process description is enough to begin a more detailed review.
Architecture × exposure technology gives the platform direction. The exact wafer handling, overlay, field size, automation and installed options still depend on the specific machine.
Question 01How Is the Pattern Exposed?
Wafer Stepper
Projects one exposure field, moves the wafer stage and repeats the pattern across the wafer.
Review exposure field, reduction ratio, overlay, wafer size and throughput.Lithography Scanner
Synchronously scans the reticle and wafer during exposure for larger fields and advanced imaging performance.
Review scanning stage, source, overlay, track integration, automation and fab requirements.Mask Aligner
Aligns the mask and wafer for contact, proximity or related exposure modes used in research and specialty production.
Common review areas include substrate size, alignment, exposure mode and automation level.Question 02Which Exposure Technology Does the Platform Use?
i-line
Widely used in mature-node, MEMS, power semiconductor, compound semiconductor and advanced-packaging applications.
Confirm wafer size, process compatibility and lamp/source condition.KrF DUV
248 nm projection lithography for finer patterning than typical i-line platforms.
Confirm process layer, laser/source configuration, resist system and installed options.ArF DUV
193 nm dry or immersion lithography used for higher-resolution semiconductor patterning.
Confirm imaging target, overlay, automation, stage, software and facility conditions.EUV
An advanced lithography branch used for selected critical layers in leading-edge manufacturing.
EUV is not representative of the wider used lithography equipment market.
“Scanner” identifies the exposure architecture.
×
“KrF” identifies the exposure technology. Neither term alone confirms wafer size, automation, installed configuration or actual machine condition.
Start With a Model, Photo or Basic Requirement
You do not need a complete lithography specification before contacting us. Send the information already available, and we will ask only for the details needed for the next decision.
What Happens Next
We turn the initial information into a practical equipment direction, then check real supply options and review a specific machine before quotation or further technical discussion.
Identify the Equipment Direction
Use the model, photo, wafer size, application and existing line to narrow the likely equipment family, exposure technology and missing information.
Check Availability, Sourcing and Replacement Options
Review current listings, other verifiable supply channels, discontinued platforms, related spare parts and possible replacement directions.
Review a Specific Machine
Once a machine is identified, confirm the actual model, photos, known condition, configuration evidence and the quotation or delivery scope that still requires discussion.
Need a replacement system, discontinued platform, spare part or technical review?
Send Your Request
Send the model, machine photo, nameplate, part number or fault description. Our equipment, technical and after-sales teams can review the next purchasing or support direction.
Confirm the Order Before Delivery, Then Inspect the Equipment After Arrival
For a large used lithography machine, the practical focus is simple: confirm exactly which machine and support scope were agreed, then document the equipment condition before installation or power-on.
Confirm the Machine, Spare Parts and Delivery Scope
The quotation or order confirmation should make the main commercial boundaries clear without requiring the buyer to decode a long technical checklist.
- The machine being supplied
Confirm the manufacturer, complete model, actual machine photos, known condition and the configuration agreed for the order.
- Included equipment and recommended spare parts
Confirm the equipment and accessories included in the delivery list. For discontinued or continuously operated platforms, also consider preparing critical spare parts to reduce the risk of production stoppage after a sudden failure.
- Deinstallation, packing and delivery terms
Confirm whether the machine is sold in place or prepared for shipment, who coordinates deinstallation and packing, and whether delivery ends at the equipment site, warehouse, port or agreed destination.
- Warranty, service period and technical support
Any warranty, repair-response period, remote support, installation assistance or other service should be stated for the specific machine and quotation.
Spare-parts planning can be part of the same discussion. Send a part number, label or photo if you want us to review available lithography machine parts or possible replacement directions.
Inspect the Equipment Before Installation or Power-On
Receiving checks help preserve evidence and identify transport or delivery problems before installation work changes the condition of the machine.
- Document the packaging and unloading condition
Photograph the crate, transport indicators, unloading process and any visible impact, tilt, moisture or external damage.
- Verify the machine and agreed delivery list
Check the model, serial number, main equipment and agreed accessories against the packing list and pre-shipment records.
- Do not power on before site conditions are confirmed
Confirm electrical supply, cooling, gases, exhaust, environment, transport locks and engineering responsibility before energizing the equipment.
- Send evidence if anything is abnormal
Provide photos, video, alarm information, damaged-area details or part labels so the technical and after-sales team can review the next step.

Discuss Support or Spare Parts
Whether the issue appears before purchase, during replacement evaluation or after delivery, you can send machine photos, nameplates, alarm screens, fault descriptions or part labels for further review.
Semiconductor Lithography Machine FAQ
Practical answers for equipment identification, sourcing, platform differences, used lithography machine prices and receiving checks.
Can you identify a lithography machine from a photo or nameplate?
A clear machine photo, nameplate, controller screen or part label may help identify the manufacturer, model family and the next details that need to be checked. Identification from a photo is preliminary and should be confirmed against the physical machine and documentation.
What is the difference between a wafer stepper and a lithography scanner?
A stepper exposes one field and then moves the wafer to the next position. A scanner moves the reticle and wafer synchronously during exposure. The correct choice also depends on the exposure technology, wafer size, overlay, field, throughput, automation and actual machine configuration.
Can you source a lithography machine or spare part that is not currently listed?
You can send the manufacturer, model, photo, nameplate, application, fault description or part number. We can review current availability, verifiable sourcing options, replacement-system directions or lithography machine parts, but availability and compatibility must be confirmed for the specific request.
Why can two used lithography machines have different prices?
Even when two machines belong to the same platform family, they may differ in suffix, configuration, condition evidence, included accessories, packing scope, delivery route and agreed support. The practical question is not which number is lower, but what specific machine and delivery scope are actually being offered.
Can a used lithography machine connect to our existing track system?
Potentially, but wafer format, cassette or FOUP handling, physical layout, recipe flow, host communication, automation standards and throughput balance must be checked. Platform names alone do not prove track compatibility.
What should be checked when the equipment arrives?
Document the external packaging and unloading condition, compare all equipment and accessories with the packing list, verify serial numbers and transport locks, inspect for damage or moisture, and confirm facility conditions before power-on. If an issue appears after delivery, you can also send photos, video, alarm information or part labels so the next support step can be reviewed.
Send a Model, Machine Photo, Nameplate, Process Requirement or Part Number
Start with whatever information is available. We can review the equipment direction, current availability, actual machine configuration, spare-part request, replacement-machine possibilities or post-delivery issue information that still needs technical review.
