Thin film deposition engineer in Dholera
A thin film deposition engineer grows and lays down the ultra-thin layers of material that build up a chip, one film at a time. Using methods like CVD, PVD and atomic layer deposition, you control thickness, purity and uniformity to a very fine degree. This guide covers the daily work, the qualifications that open the door, how careers progress, honest notes on pay, and how the role fits the semiconductor fab being built at Dholera.
What the role involves
A chip is built from many stacked layers, and deposition is the step that adds each one. As a thin film deposition engineer you own the processes that grow or deposit films of metal, oxide, nitride or other materials onto the wafer, using techniques such as chemical vapour deposition, physical vapour deposition and atomic layer deposition. Your daily job is to hit the exact thickness, composition and uniformity the design needs, then keep every wafer identical. You monitor deposition rate, film thickness, stress and uniformity across the wafer, and adjust the recipe when any of them drift. You spend time at the deposition tools in the cleanroom and time in data analysis chasing defects and yield problems. You work closely with etch, lithography, integration and equipment teams, since your film quality shapes what the next steps can do. Safety matters because deposition uses reactive gases, high temperatures and sometimes toxic precursors. As with every fab step, recipe changes are documented and tightly controlled, and much of your value lies in keeping a stable deposition process stable over long runs.
Skills and qualifications
Deposition engineers usually hold a B.Tech or B.E. in materials, chemical, electronics, electrical or mechanical engineering, and many hold an M.Tech in materials science, microelectronics or a related field. Materials science and surface chemistry knowledge is directly useful because film growth is about controlling how materials form on a surface. Core skills include statistical process control, design of experiments, and reading thickness, stress and uniformity data with tools like JMP or Minitab. You will learn to operate and tune CVD, PVD and ALD tools and their control software on the job, since these are specialist machines. Precision, patience and disciplined documentation are essential because film quality affects everything built on top of it. Cleanroom protocol and gas and chemical safety training are mandatory. Graduate trainee schemes, India Semiconductor Mission skilling programmes and NATS apprenticeships help new engineers build the tool-specific and materials knowledge that most degree courses only touch lightly, making them a practical route into the role for fresh graduates.
Career path and progression
You usually start as a junior deposition engineer learning the tools, the film chemistry and the measurement systems under a senior engineer. As you prove you can hold thickness, stress and uniformity steady, you take full ownership of a deposition module, then grow into a senior deposition engineer handling the hardest film-quality and defect problems and mentoring juniors. From there you can specialise deeper in a technique such as ALD, move into process integration to manage how your films interact with the whole device stack, or shift toward equipment engineering given how tool-driven deposition is. Yield engineering, failure analysis and materials development are common adjacent moves. A management track leads to module lead and section manager, while a technical track lets you grow as a staff or principal engineer. Deposition and materials expertise transfers well across companies and to equipment and precursor suppliers, and skilled deposition engineers are valued worldwide, so a solid track record brings real career mobility.
Pay, honestly
Pay for deposition engineers in India depends on your degree, your experience and the employer, so treat any single number cautiously. Qualitatively, entry-level deposition engineers earn a stable starting salary, mid-level engineers with proven film control earn clearly more, and senior specialists who can solve difficult film-quality problems command a strong premium. As an indicative annual CTC range for the broader Indian semiconductor engineering market, roughly Rs 6 to 20 lakh from entry to senior is commonly reported, indicative, varies by employer and experience, and never a guarantee. A brand-new fab in a greenfield location such as Dholera may set pay differently to attract scarce talent, and these figures are not Dholera-specific. Advanced degrees, niche technique expertise such as atomic layer deposition, and a record of raising yield tend to move pay up fastest. Always confirm the real figure directly with the specific employer rather than relying on published ranges.
How this role fits Dholera
The Dholera fab is being built by Tata Electronics with PSMC, approved by the Union Cabinet on 29 February 2024 under the India Semiconductor Mission, with a reported investment of about Rs 91,000 crore and capacity of up to 50,000 wafers per month on 300 mm wafers. Reported process nodes span 28, 40, 55, 90 and 110 nm, starting at mature nodes and moving toward 28 nm, for products reported to include power-management ICs, display driver chips, microcontrollers and high-performance computing logic. Deposition is fundamental to building every layer of these chips, so deposition engineers are essential to the line. Reported direct plus indirect jobs exceed 20,000, with about 100,000 cited as a wider multi-fab target. As of mid-2026, reports describe cleanroom fit-out and equipment move-in underway, first trial wafers targeted around December 2026 and commercial-scale production reported around mid-2028, so no chip is confirmed produced yet. The Ahmedabad-Dholera Expressway has been operational since 31 March 2026. Skilling routes run through ISM, ITI, diploma, B.Tech and NATS apprenticeship programmes.
FAQ
What is the difference between CVD and PVD?
CVD, chemical vapour deposition, grows films through chemical reactions of gases on the wafer surface. PVD, physical vapour deposition, physically transfers material, often by sputtering, onto the wafer. Each suits different films and layers, and many deposition engineers work across both depending on the process.
Do I need a materials science degree for this role?
It helps, since deposition is about controlling how materials form on a surface, but engineers from chemical, electronics, mechanical and related branches also do the role well. Specialist film and tool knowledge is usually built on the job and through skilling programmes rather than assumed from the degree.
How is a deposition engineer different from a CVD/PVD technician?
A deposition engineer designs and optimises the film recipes and solves process problems, usually with a degree background. A technician operates and maintains the deposition tools, loads wafers and follows set procedures. The two roles work closely together on the same equipment.
