  • Ceramic-metal substrate with low amorphous phase
    Patent number: 11430741
    Abstract: A ceramic-metal substrate in which the ceramic substrate has a low content of an amorphous phase. The ceramic-metal substrate includes a ceramic substrate and on at least one side of the ceramic substrate a metallization. The ceramic-metal substrate has at least one scribing line, at least one cutting edge, or both at least one scribing line and at least one cutting edge. Amorphous phases extend parallel to the scribing line and/or the cutting edge in a width of at most 100 ?m or of at least 0.50 ?m.
    Type: Grant
    Filed: May 15, 2018
    Date of Patent: August 30, 2022

  • Laser cutting of metal-ceramic substrates
    Patent number: 11383321
    Abstract: The present application relates to a method of laser ablation of a metal-ceramic substrate, in which a laser is used under process conditions in which the formation of solid metal particles on the metal-ceramic substrate, which can separate from metal particles released by laser ablation near the ablation edge, is essentially avoided. Further the present application relates to a ceramic-metal substrate comprising a ceramic substrate and a metallization on at least one side of the ceramic substrate, wherein the ceramic substrate and the metallization have flush cutting edge.
