Raw Description
Product | Micro-LED chips, micro-LED display modules, micro-LED photoelectric measurement equipment. | Applications: | Smartwatches, AR/VR, smartphones, and tablets. | Technology | Micro-LED technology uses self-emitting micron-scale LEDs as pixel units and assembles them on a driving backplane to form a high-density LED array, that is, LED miniaturisation and matrix technology. The integration of high-density, small-sized LED arrays is the result of thinning and miniaturising the LEDs. Each pixel is usually less than 50μm with individual addressing and driving to emit light. Compared with LCD and OLED displays, micro-LED has self-emitting advantages, high efficiency, low power consumption, high integration, high stability, and all-weather work, and is considered the most promising next-generation display and a light-emitting device. || Sitan Semiconductor International Co. Limited focuses on the development, production and sales of micro-LED. We aim to solve practical problems in the process of micro-LED and industrialisation. We are committed to leading and promoting the development of the new micro-LED display industry while integrating high-quality investment resources to achieve mass production of micro-LED. | Description | Turnkey solution provider of micro-LED display technology

Strategic Analysis

Executive Brief

Sitan Semiconductor is a specialized "Turnkey Solution Provider" in the Micro-LED space, focusing on the miniaturization of LED arrays (pixels < 50µm) for AR/VR, wearables, and mobile displays. Their core engineering challenge lies in the "Mass Transfer" and "Thermal Management" of ultra-high-density pixels, where non-radiative recombination and heat accumulation directly limit brightness and device lifespan.

Strategic Fit & Lead Score

Lead Score: 78 (Adjacent Tech / Strong Potential)

Why this Score? Micro-LED technology is hitting a "Thermal Wall." As Sitan drives pixel density higher for AR/VR applications, the heat flux at the micron scale becomes too intense for traditional sapphire or silicon substrates. 6C’s Diamond technology offers the only material platform capable of managing this heat while providing the optical transparency required for high-end display modules. Furthermore, 6C can provide the specialized MPCVD hardware Sitan needs to develop "GaN-on-Diamond" architectures in-house.

6C Solutions Proposal

Application Area 6C Solution Technical Value Prop
Thermal Management PCD Wafer (Poly Crystalline) Integration of PCD as a sub-mount or carrier for Micro-LED arrays. Diamond's thermal conductivity (> 1800 W/mK) is 5x that of Copper, eliminating "hot spots" in < 50µm pixels and preventing thermal wavelength shift.
Next-Gen Substrates Custom Coating (Direct Diamond) 6C can provide direct Diamond-on-Silicon or Diamond-on-Nitride coating services. This allows Sitan to grow or transfer Micro-LEDs onto a diamond-enhanced backplane, drastically reducing thermal resistance at the junction.
AR/VR Optics SCD Optical Windows For AR/VR projection modules, 6C’s Single Crystal Diamond (SCD) provides the highest possible transparency and refractive index stability, ensuring zero distortion even under high-intensity light output.
Manufacturing Tooling Diamond-Coated Transfer Stamps Micro-LED "Mass Transfer" requires precision stamps. 6C’s custom diamond coatings provide ultra-low friction, high wear resistance, and high thermal stability for the pick-and-place or bonding heads used in Sitan’s production line.
In-House R&D Custom MPCVD Reactor System Enable Sitan to bring diamond synthesis in-house. 6C can build a bespoke reactor optimized for 2" to 4" wafer processing, allowing Sitan to experiment with Diamond-on-GaN recipes for their proprietary "Turnkey" modules.

Engagement Hooks

  • Technical Question: "As Sitan scales Micro-LED pixel density for AR/VR applications, how are you addressing the non-radiative recombination and efficiency droop caused by localized thermal bottlenecks on traditional backplanes?"
  • Value Statement: "6C can help Sitan break the 'Luminance Ceiling' by replacing standard thermal management with MPCVD diamond, allowing your Micro-LED modules to run 30% brighter with 2x the operational stability."
