摘要:
In a method for producing a multilayer ceramic substrate by a non-shrinkage process, even when a total area of surface electrodes on a first principal surface side is smaller than that on a second principal surface side, a favorable balance in terms of a time period from softening to crystallization of glass is achieved between the first principal surface side and the second principal surface side, thereby allowing all base material layers to be densified and prevented from causing cracks or warpage, even when the crystallization temperature is lowered to prevent production of a reaction layer. The crystallization temperature of a glass material included in a second base material layer defining a second principal surface with a larger total area of surface electrodes is less than that of a glass material included in a first base material layer defining a first principal surface.

摘要:
The present invention relates to a ceramic dielectrics. It is difficult to downsize a MgTiO.sub.2 -base ceramic composition conventionally used, having an insufficiently high relative dielectric constant (.di-elect cons..sub.r), less than 20, while a CaTiO.sub.3 -base ceramic composition, having a small value of Q, is not suitable for electronic devices processing a signal in the high-frequency-bandwidth. Moreover, it is difficult to control the temperature coefficient of resonant frequency of these conventional ceramic compositions. In the present invention, a ceramic dielectrics having a composition represented by xMgTiO.sub.3.(1-x)CaTiO.sub.3.y(Ln.sup.1.sub.1-w Ln.sup.2.sub.w).sub.2 Ti.sub.2z O.sub.3+4z (wherein Ln.sup.1 and Ln.sup.2 are lanthanoids, and w, x, y, and z are values in the ranges of 0.ltoreq.w
摘要:
A high-quality resistor pattern and conductor pattern is formed on an external surface of a multilayer ceramic substrate by an ink jet method. A composite sheet including a first ceramic green layer and a shrinkage-retardant layer is formed, and a resistor pattern and a conductor pattern are formed on the first ceramic green layer of the composite sheet by an ink jet method. Subsequently, a plurality of second ceramic green layers are stacked with the composite sheet such that the shrinkage-retardant layer of the composite sheet defines an outermost layer, thus forming a multilayer composite including an unfired multilayer ceramic substrate and the shrinkage-retardant layer. Then, the multilayer composite is fired, and the shrinkage-retardant layer is removed to obtain a sintered multilayer ceramic substrate.
