  • Tape composition and process for internally constrained sintering of low temperature co-fired ceramic
    Patent number: 7147736
    Abstract: The present invention relates to a method to achieve the suppression of planar shrinkage in LTCC ceramic tape laminate structures without externally applied forces or sacrificial constraining tape. The method utilizes a non-sacrificial constraining tape that constrains a tape assembly.
    Type: Grant
    Filed: May 24, 2004
    Date of Patent: December 12, 2006
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Carl Baasun Wang, Kenneth Warren Hang, Christopher Roderick Stewart Needes
  • Process for the constrained sintering of asymmetrically configured dielectric layers
    Patent number: 6827800
    Abstract: A method to produce a distortion-free asymmetrical low-temperature co-fired ceramic structure comprising at least one layer of glass-containing internal constraining tape and at least one layer of glass-containing primary tape wherein the internal constraining tape and the primary tape are laminated to form an asymmetrical laminate and wherein a release layer is deposited on at least one surface of the laminate forming an assembly, wherein the surface is opposite the position of greatest asymmetry of the laminated layers and wherein the assembly is thermally processed producing a structure exhibiting an interactive suppression of x,y shrinkage.
