Fab Materials and Chemicals

The consumables a wafer fab burns through continuously.

Photoresists, slurries, acids, solvents, gases and precursors. Unlike equipment, these are consumed on every wafer, so a supply interruption stops production within days rather than quarters.

What these figures mean
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.

Photoresists

The light-sensitive polymer that records the circuit pattern. Formulated per node and per tool, and made almost entirely in Japan.

TierC
Imported 100%
EntryNot MSME

Resist Ancillary Chemicals

The developers, anti-reflective coatings and edge-bead removers used with resist. Higher volume than the resist itself and considerably less exotic.

TierB
Imported 100%
Entry>Rs 15 Cr

Photomasks and Reticles

The quartz plates carrying the patterns a scanner projects onto the wafer. A leading-edge mask set costs more than most factories.

TierB

EntryNot MSME

CMP Slurries and Pads

The abrasive suspensions and polyurethane pads that do the actual planarisation. Consumed continuously and formulated per material being polished.

TierB
Imported 100%
EntryRs 5–15 Cr
Qualify18–30 mo

Process Acids and Solvents

Hydrofluoric, sulphuric, nitric and phosphoric acids plus the solvent set, purified to SEMI grades where contamination is measured in parts per trillion.

TierB

Entry>Rs 15 Cr

Specialty Process Gases

Nitrogen trifluoride, silane, tungsten hexafluoride and the halogen set: the reactive gases that etch and deposit, most of them dangerous.

TierC

EntryNot MSME

Dopant Gases

Phosphine, arsine, diborane and boron trifluoride: the sources of the impurity atoms that make silicon into a semiconductor. Among the most toxic materials in industry.

ALD and CVD Precursors

Organometallic compounds that decompose on a hot wafer to leave behind a film, the chemistry that makes high-k gates and atomic-layer films possible.

TierC

Entry>Rs 15 Cr

Sputtering Targets

High-purity metal discs consumed by physical vapour deposition tools: copper, titanium, tantalum, tungsten and aluminium at five nines purity and above.

TierB

Entry>Rs 15 Cr

Electroplating Chemistry

The copper baths and organic additive packages that fill damascene trenches and vias without voids. The additives are the product; the copper sulphate is not.

Filtration and Purification Components

Filters, membranes, resins and purifiers that sit at the point of use on every chemical and gas line, catching what the supply chain missed.
