PhotonSilica | PHSI Technologies & Research Pvt. Ltd.

PhotonSilica is R&D FabLab + design house accelerating semiconductor innovation—built in India, for the world. We turn Indian research into domain-qualified silicon for defence & space, automotive, telecom, consumer electronics, data centers, and industrial electronics. No bottlenecks, no Reduced foreign dependency—just rapid, affordable, on-demand prototyping with qualification-first ownership. Fabless today and scaling our R&D FabLab in phases, we carry designs from spec to silicon bring-up and qualification, delivering secure, production-ready chips faster and more cost-effectively.

About Us

PhotonSilica | PHSI Technologies And Research Pvt. Ltd. is a semiconductor R&D design house and FabLab dedicated to turning Indian research into domain-qualified silicon for defence, space, automotive, telecom, consumer, data center, and industrial applications.

We operate as a fabless design house today, building end-to-end capabilities across ASIC/SoC design, verification, and qualification, while scaling a phase-wise R&D FabLab to accelerate on-shore prototyping and testing.

PhotonSilica bridges academia, industry, and government to deliver chips that are not only designed in India, but also qualified for mission-critical use. Our qualification-first approach ensures every design progresses beyond GDSII to EMI/EMC, reliability, and radiation validation through accredited partners.

Our workflow supports:

  • Custom ASIC & SoC design (digital, mixed-signal, RF-adjacent)

  • Reusable IP for secure MCU/crypto, sensor-fusion, PMIC, and radar DSP

  • Prototyping orchestration via multi-foundry MPW routes and local OSAT partners

  • Qualification & compliance for defence, automotive, and industrial standards

Recognitions & programs:
Backed by DPIIT (Startup India), Startup UP, and MSME (Udyam), PhotonSilica is also a beneficiary under the Design-Linked Incentive (DLI) Scheme of the India Semiconductor Mission, Ministry of Electronics & IT, Government of India—aligning with the national vision to strengthen on-shore innovation, manufacturing readiness, and strategic self-reliance.
