Lotus Power Interposer Technology

Precise silicon etching

Revolutionizing Power Management with Advanced Interposer Technology

Lotus Microsystems introduces advanced packaging to the power management field with our proprietary power interposer technology, enabling the use of silicon interposers in power applications. Our interposer design and processes are optimized to handle higher currents and endure higher voltages.

  • Thick-copper redistribution layer (RDL) patterning

  • Double-sided wafer routing

  • Precision silicon etching

  • High-aspect ratio through-silicon vias (TSV)

Enhanced Thermal Performance with Power Interposer Technology

Compared to conventional power module packaging using laminate substrates and lead frames, the Lotus Power Interposer delivers up to 60% better thermal performance while eliminating hot spots. This enables higher power density and reduces derating at the maximum allowable temperature on the application platform.
