Title:
MULTILAYER GLASS CERAMIC DIELECTRIC MATERIAL, SINTERED BODY, METHOD FOR PRODUCING SINTERED BODY, AND CIRCUIT MEMBER FOR HIGH FREQUENCY USE
Document Type and Number:
WIPO Patent Application WO/2022/168624
Kind Code:
A1
Abstract:
The present invention provides: a multilayer glass ceramic dielectric material which has low dielectric characteristics and high mechanical strength in a high frequency range of 20 GHz or more; a sintered body; and a circuit member for high frequency use. A multilayer glass ceramic dielectric material according to the present invention is characterized by having a multilayer structure wherein at least an outer layer, an inner layer and another outer layer are sequentially stacked, and is also characterized in that: the outer layers are formed of a material which has a relative dielectric constant of 5.5 or less at a measurement temperature of 25°C at a frequency of 28 GHz after being sintered; and the inner layer is formed of a material, the thermal expansion coefficient of which after sintering is higher than the thermal expansion coefficient of the outer layers after sintering.
