Executive Brief
PrimaNova Technologies Limited is a specialized semiconductor firm focusing on the design and manufacture of Gallium Nitride (GaN) power devices and integrated circuits (ICs). They primarily target the high-growth markets of ultra-fast charging, data center power supplies, and automotive electrification. Their technical core revolves around maximizing power density and efficiency in small form factors—areas where thermal bottlenecks are the primary limiting factor for performance.
Strategic Fit & Lead Score
Lead Score: 92/100
Why this Score? PrimaNova operates in the GaN-on-Si and GaN-on-SiC space. As power densities in GaN devices exceed 10W/mm, the "Thermal Wall" becomes a critical failure point. 6C’s ability to provide high-thermal conductivity Polycrystalline Diamond (PCD) substrates and direct-growth coating services offers PrimaNova a roadmap to 3x-5x higher power densities than standard Silicon or SiC substrates. Furthermore, their focus on high-efficiency power conversion makes them a prime candidate for transitioning to GaN-on-Diamond architectures.
6C Solutions Proposal
| Application Area | 6C Solution | Technical Value Prop |
|---|---|---|
| Extreme Thermal Management | PCD Heat Spreaders (Thermal conductivity >1800 W/mK) | Passive cooling performance 4x better than Copper and 2x better than BeO; eliminates thermal throttling in high-frequency GaN RF/Power ICs. |
| Advanced Substrate Integration | Direct Diamond Growth / Coating | Reducing the junction-to-ambient thermal resistance (Rθjc) by growing diamond directly on the backside of GaN wafers after substrate removal. |
| Device Packaging | SCD Sub-mounts (Single Crystal) | For high-reliability automotive or aerospace applications, 6C’s SCD provides the highest possible thermal flux and mechanical stability for discrete power transistors. |
| In-house Fabrication | Custom MPCVD Reactor Build | Enables PrimaNova to bring diamond-layer deposition in-house, integrating diamond growth directly into their CMOS-compatible GaN fab workflow. |
| Purity Control | 9N High-Purity H2 Generators | Essential for PrimaNova’s cleanroom environment to ensure zero-defect epitaxial growth and prevent carrier trapping in power devices. |
Engagement Hooks
- Technical Question: "What is the current junction temperature limit (Tj) of your GaN-on-Si power stages before you see significant RDSon degradation, and how much performance are you leaving on the table due to substrate thermal resistance?"
- Value Statement: "6C can help PrimaNova break the 20W/mm barrier by replacing standard heat sinks with MPCVD Diamond, effectively tripling your power density without increasing device footprint."
