🔬 Silicon capacitors are becoming important for Intel's EMIB packaging, benefiting suppliers like SEMCO and Murata

high convictionFirst mentioned May 28, 2026

Silicon capacitors are becoming important for Intel's EMIB packaging, benefiting suppliers like SEMCO and Murata. SEMCO's unique position as the only company with both silicon capacitor and substrate businesses allows it to supply turnkey solutions to Intel, driving its stock surge.

Evidence & details
Evidence
  • +SEMCO secured a silicon capacitor supply contract worth over $1 billion for Intel's EMIB.
  • +SEMCO's silicon capacitor revenue was only a few million dollars last year, indicating rapid ramp.
  • +SEMCO is the only company operating both silicon capacitor and substrate businesses, maximizing bargaining power.
  • +Murata maintains a close relationship with Ibiden, Intel's first-vendor for substrates, positioning it to benefit.
Catalysts
  • âš¡Rise of Intel's EMIB packaging technology
  • âš¡Intel's need to source silicon capacitors externally
  • âš¡Turnkey supply model for substrates and capacitors
Risks
  • −Dependence on Intel's EMIB adoption and volume
  • −Competition from existing suppliers like Murata and TSMC
  • −Potential technology shifts or supplier diversification by Intel
