TCAD and Process Simulation

Physics-based simulation of how a device will behave before anyone builds one: dopant diffusion, electric fields, breakdown voltage and thermal response.

Tier B: Right Opportunity, Wrong Mental Model Medium criticality

A small but genuinely open services niche where Indian academic strength could convert into a business serving the new compound-semiconductor fabs.

What It Does

Predicts how a chip will behave before anyone builds it

Simulates the physics inside a device: heat, voltage, current flow.
Matters most for newer materials like India's SiC and GaN push.
A small, specialist niche with real Indian academic strength.

India Position

Import dependency: Not established
Made in India today: None
MSME entry capital: Under Rs 1.5 Cr
Time to qualify: 6–12 months

Not established means we hold no sourced import figure for this input yet, not that India imports none of it. Read Made in India today for the domestic picture.

Indian institutions use TCAD extensively for research. No commercial Indian tool or service business of scale exists.

What Breaks, and Who Could Fix It

What breaks

TCAD matters most where the device is novel (power, compound semiconductors, sensors) which is exactly where India’s SiC and GaN ambitions sit.

Who could fix it

The customer base is small and largely institutional. This is a specialist consultancy rather than a scalable product business.

Best and worst case

Best case if this breaks

A small, specialised market with several credible vendors and strong academic tool availability alongside the commercial ones.

Worst case if this breaks

Simulation is only as good as the calibration data behind it, and that data comes from a fab. Without one, models stay generic.

Best case to fix it

Device modelling and simulation services are a legitimate low-capital business, and Indian academic depth in semiconductor physics is real.

Worst case to fix it

Building a TCAD tool from scratch competes with decades of calibrated physics models. Not sensible.

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.
