Contribute to IC substrates as thinner and smaller and low warpage.

New branding announcement

  • Panasonic Electronic Materials Division launches a new product brand for the Semiconductor Device Materials business.
    The LEXCM brand now comprises all of the Semiconductor Device Materials; IC packaging materials (which includes substrates, encapsulants and underfills) and electronic assembly materials.
    Additionally, the IC substrate materials' brand is transitioning from MEGTRON GX to LEXCM GX.
