Interactive supplier map
The interactive supplier map lays out the companies in the Dholera semiconductor fab ecosystem by the role they play, from lithography and deposition equipment to gases, chemicals, materials and facility services. It is a way to see how a fab is supplied, not a directory that endorses any vendor.

What the supplier map does
The interactive supplier map organises the semiconductor supply chain that a fab like the Tata Electronics and PSMC plant at Dholera depends on. A modern fab does not run alone, it needs equipment for lithography, etch, deposition, metrology and inspection, along with ultra-pure gases, specialty chemicals, photoresist and other materials, plus water treatment, precision engineering and facility management. The map groups the named global and ancillary suppliers in the fact base by these functions, so you can see at a glance which category a company sits in and how the pieces of a fab supply chain fit together. It is built as an explainer of how chip manufacturing is supplied, presented neutrally, and it does not rank vendors or recommend any commercial relationship.
How to use it
Start from the category you care about, for example lithography, wet chemistry or gases, and select it to see the suppliers associated with that function. Each node links through to that supplier's own page in the Atlas, where its role in the ecosystem is described in plain language. If you are a business exploring whether you could supply the fab, use the map to understand where your capability fits and then read the how to become a supplier and vendor onboarding pages for the practical steps. If you are simply learning how chips get made, the map pairs well with the how chips are made and what is a semiconductor fab pages. Treat named companies as illustrative of the roles involved, drawn from reported partnerships and general industry structure, and always verify any current commercial arrangement directly with the companies concerned rather than assuming a listing implies a confirmed contract.
What it is not
The supplier map is an educational overview, not a procurement portal or an endorsement. Some suppliers are named because partnerships have been reported, such as the Tata Electronics and ASML lithography partnership, while ancillary categories represent the general classes of vendor any fab needs rather than confirmed Dholera contracts. Where a relationship is only reported or at MoU stage, the linked page says so. Use the map to build understanding and to orient your own research, and confirm anything commercially significant against primary company sources.
