izmo Ltd. (NSE: IZMO) has achieved a significant technological breakthrough in India’s space and semiconductor ecosystem, marking a major step forward for advanced electronics manufacturing under the Make in India initiative.
izmo Ltd. announced that its specialised division, izmo Microsystems, has successfully designed and developed a high-complexity 3D System-in-Package (SiP) module for Space Payload Camera Electronics. The solution is based on an advanced 3D SiP architecture with stacked substrates, engineered to meet the stringent reliability and performance standards required for space-grade electronics.
One of the most notable achievements of this development is the dramatic reduction in size. Traditional PCB-based electronics measuring 200 mm × 200 mm have been completely re-engineered into a compact 81 mm × 81 mm SiP module, delivering an 84% reduction in footprint. This miniaturisation has been achieved by integrating active components in bare-die form onto a stacked-substrate configuration using high-density wire bonding, enabling high routing density and multi-functional integration within an extremely small form factor.
The module is housed in a fully indigenised custom hermetic ceramic package that has been designed and fabricated entirely in India. This hermetic enclosure is critical for ensuring environmental robustness and long-term reliability in the extreme thermal cycles and vacuum conditions encountered in space missions. Managing signal integrity and thermal dissipation at such high densities within a limited volume represents a major technical challenge, underlining the sophistication of this achievement.
This breakthrough positions izmo Microsystems among a very small group of global Tier-1 aerospace technology players with proven capabilities in advanced 3D heterogeneous integration for space applications. Unlike conventional SiP solutions that are typically designed for commercial electronics, this development represents a strategic shift toward mission-critical space electronics, where performance, reliability, and survivability are non-negotiable.
From a strategic standpoint, the indigenous development of 3D vertical stacking technology and hermetically sealed ceramic packaging significantly reduces India’s dependence on restricted foreign technologies for critical space and defence applications. It also lays a sovereign technological foundation for future domains such as Silicon Photonics and Quantum Communications, where traditional packaging approaches are increasingly inadequate.
