DUV Lithography Scanners

Argon fluoride, krypton fluoride and i-line systems that pattern everything from 7nm down-rev layers to the mature nodes India is actually building.

Tier C: Not a Founder’s Game Yet High criticality

Three global suppliers, all with decades of optical and stage engineering behind them. Not enterable.

What It Does

The everyday printer chips at more common nodes are made on

The workhorse printing machines used for most non-cutting-edge chips.
Three companies compete, more choice than the leading-edge machine has.
This is exactly what India's own fab plans depend on.

India Position

Import dependency: 100%
Made in India today: None
MSME entry capital: Not an MSME entry
Time to qualify: Over 30 months

Basis: No lithography equipment is manufactured in India; every scanner in an Indian fab plan is imported.

What Breaks, and Who Could Fix It

What breaks

ASML holds the great majority of new sales, and immersion tools carry the same export-licence exposure as EUV in several jurisdictions. Nikon and Canon matter most at the mature end.

Who could fix it

Tool installation and hook-up around lithography is the same skilled trade covered under equipment services, and it is the practical way an Indian firm touches this equipment.

Best and worst case

Best case if this breaks

Three suppliers exist rather than one, and the second-hand market for mature-node steppers is genuinely liquid.

Worst case if this breaks

A mature-node fab plan built on second-hand tool availability is a plan built on someone else’s upgrade cycle. Availability has tightened sharply since 2023.

Best case to fix it

No system-level route. Reticle handling, environmental control and facility interfaces are the accessible periphery.

Worst case to fix it

The tool itself will remain imported for the foreseeable future.

Reading Key

Every entry carries the same five figures, so two inputs anywhere in the chain can be compared directly. What each one is, and what it is not:

Import dependency: The share of Indian demand for this input that is met by imports today. A percentage is published only where we can state the basis for it, and the build rejects a figure that has none. “Not established” means no sourced figure exists yet, not that the figure is zero; for the domestic picture, read “Made in India today” instead.
Made in India today: How much of this input is actually produced in India: none, pilot scale, partial, or established. This is the field to read when import dependency is not established.
MSME entry capital: What it would plausibly cost an Indian MSME to enter this input at the smallest viable scale, in crore rupees. Plant and equipment only; it excludes working capital and the qualification cycle.
Time to qualify: How long from a working sample to a qualified first shipment, once the line exists. Qualification, not construction, is what usually decides whether an entry succeeds.
India readiness tier: Our verdict on whether an Indian founder can realistically enter this input, derived from the four figures above and stated as one of three tiers.

The three tiers

Tier A: Buildable Now: Under roughly Rs 5 crore of entry capital and 12 to 24 months to a qualified first shipment. A founder can start here.
Tier B: Partnership or Distribution: There is real money here, but not in manufacturing the thing. The opening is in stocking, distribution, purity uplift or a licensed partnership.
Tier C: Not Yet: Requires a joint venture, a technology licence, or a multinational’s balance sheet. Worth understanding, not worth starting.

Made in India today

None: No Indian production we can identify. Demand is met entirely from abroad.
Pilot scale: Made in India at laboratory, pilot-line or single-customer scale only.
Partial: Real Indian production exists, but it covers part of the range or part of the demand.
Established: Indian production is routine and qualified, at commercial volume.

Confidence

Confidence describes how well evidenced our listing is. It is not a rating of the supplier or of its products.

Verified: Checked against a primary source: the firm’s own filing, product documentation or announcement.
Reported: Consistently reported by trade press or industry analysts, but we have not seen the primary document ourselves.
Likely: A credible supplier for this input given their product range, though we have not confirmed that they actually supply it.
Directional: Included to show the shape of the market. Read it as an observation, not as a claim about this firm.

Scale

Scale is a bucket, not a revenue figure. We publish a band we can hold for years rather than a number that is stale in a quarter.

Mega: A global top-tier firm that effectively sets the price and the standard for this input.
Large: A major international supplier, usually with plants or sales in several regions.
Mid: An established specialist, often strong in one region or one product family.
Small: A niche or regional supplier. Frequently the realistic first partner for a new Indian entrant.
