Title:
COMPOSITE DEELECTRIC MATERIAL AND SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2004/065489
Kind Code:
A1
Abstract:
The oxide of a transition metal element having at least two valences of less than four is allowed to be contained in spherical dielectric ceramic powder. A composite dielectric material using this dielectric ceramic powder can deliver a resistivity as high as at least 1.0 × 1012 &ohm cm without compromise in dielectric characteristics.
