Definitions
- the present invention relates to a ceramic multilayer substrate and a method for manufacturing the same, and more particularly to a ceramic multilayer substrate incorporating a chip-type ceramic electronic component and a method for manufacturing the same.
- Conventional techniques of this type include a multilayer ceramic substrate with built-in electronic components described in Patent Document 1, a multilayer ceramic substrate described in Patent Document 2, and a method for manufacturing the same.
- a multilayer ceramic substrate with a built-in electronic component described in Patent Document 1 includes a multilayer ceramic substrate, a chip-type ceramic electronic component housed in a space in which a recess or through-hole force is formed in the multilayer ceramic substrate, The chip-type electronic component is provided between the multilayer ceramic substrate or in the space and provided with a conductor.
- a multilayer ceramic substrate having a desired shape without deteriorating the flatness can be obtained.
- a plate-like sintered body plate obtained by firing a ceramic functional element in advance. Therefore, functional elements such as a capacitor element, an inductor element, and a resistance element are prepared, and these functional elements are built in the unsintered composite laminate.
- the unsintered composite laminate includes a base green layer, a constraining layer containing a hardly sinterable material, and a wiring conductor. When fired, the base green layer is formed by the action of the constraining layer. Shrinkage in the main surface direction is suppressed.
- Patent Document 1 Japanese Patent Publication No. 06-32378
- Patent Document 2 Japanese Patent Laid-Open No. 2002-084067 Disclosure of the invention
- the present invention has been made to solve the above problems, and the chip ceramic electronic component is not damaged by cracks or the like, and the characteristics of the chip ceramic electronic component are not deteriorated.
- An object of the present invention is to provide a highly reliable ceramic multilayer substrate and a method for manufacturing the same.
- chip-type ceramic electronic components are greatly different, the chip-type ceramic electronic component is cracked or damaged. If the shrinkage in the surface direction of the substrate is suppressed by adopting the non-shrinkage method, chip-type ceramic electronic components that do not shrink can be incorporated.
- chip-type ceramic electronic components such as force multilayer ceramic capacitors are often composed of high dielectric constant materials, and high dielectric constant materials generally have a large coefficient of thermal expansion.
- the material of the ceramic green layer that becomes the ceramic layer is composed of a low dielectric constant material. In general, a low dielectric constant material often has a low coefficient of thermal expansion.
- Chip-type ceramic electronic parts are made of ceramic material, but the ceramic material is weak against tensile stress, so that the tensile force from the ceramic layer causes cracking or breakage. .
- the constituent material of the chip-type ceramic electronic component incorporated in the ceramic multilayer substrate is limited.

- Example 1 Example 1
- a paste layer made of thermally decomposable resin is formed on a chip-type ceramic electronic component, and fired by a non-shrinkage method to produce a ceramic multilayer substrate. Cracks in the chip-type ceramic electronic component (multilayer ceramic capacitor) Whether or not an excessive tensile force acts on the multilayer ceramic capacitor when the temperature was lowered after firing was investigated. In addition, the capacitance of the built-in multilayer ceramic capacitor was measured, and the degree of mutual diffusion of the material components was examined through capacitance fluctuations.
- a slurry was prepared using a low-temperature sintered ceramic material using borosilicate glass as a sintering aid, and this slurry was applied on a carrier film to produce a plurality of ceramic green sheets.
- a conductive paste mainly composed of Ag powder is formed with the ceramic green sheet in close contact with a smooth support base.
- the via conductor was formed by pushing it into the via hole using a metal mask.
- the same conductive paste was screen-printed on this ceramic green sheet to form in-plane conductors with a predetermined pattern. For other ceramic dally sheets, via conductor portions and in-plane conductor portions were appropriately formed in the same manner.
- the thermal expansion coefficient of the ceramic layer which is also a low-temperature sintered ceramic material force, is 7 ppm / ° C.
- a multilayer ceramic capacitor was prepared as a chip-type ceramic electronic component having a ceramic sintered body as an element body.
- This multilayer ceramic capacitor is made of ceramic sintered body (size: 1. Omm X O. 3mm X O. 3mm, internal electrode; Pd, capacity standard: 8 OpF, thermal expansion coefficient: 14ppmZ °
- the external terminal electrode part is formed by applying a conductive base composed mainly of Ag to both ends of the C! RU The external terminal electrode is not treated.
- a thin layer of thermally decomposable resin paste was applied to the outer peripheral surface of the ceramic body of the multilayer ceramic capacitor to form a paste layer.
- an organic adhesive is applied onto a predetermined ceramic green sheet using, for example, a spray, and an organic system is applied to the in-plane conductor portion.
- an organic adhesive is applied onto a predetermined ceramic green sheet using, for example, a spray, and an organic system is applied to the in-plane conductor portion.
- use a mounter to mount the multilayer ceramic capacitor to the specified in-plane conductor, and join and fix the multilayer ceramic capacitor to the in-plane conductor.
- the layered body was temporarily pressure-bonded at a pressure of, for example, lOMPa or higher.
- lOMPa As the constraining layer, Al O and ceramic
- this pressure is less than 2 OMPa, the pressure bonding between the upper and lower ceramic green sheets is insufficient, and delamination may occur during firing. If this pressure exceeds 250 MPa, the multilayer ceramic capacitor may break or the conductor pattern may break. After the main pressure bonding, the pressure-bonded body was fired in an air atmosphere at 870 ° C., and then the sheet as the constraining layer was removed to obtain a ceramic multilayer substrate having a thickness of 0.5 mm.

In Tables 1 and 2, the component means a multilayer ceramic capacitor, and the substrate means a ceramic multilayer substrate.
- Example 1 According to the results shown in Table 1, in Example 1, since no crack was detected in any of the multilayer ceramic capacitors, the paste layer between the multilayer ceramic capacitor and the ceramic layer burned. As a result, it was found that the laminated ceramic capacitor and the ceramic layer were not in close contact with each other, and the thermal stress caused by the difference in thermal expansion coefficient that occurred when the temperature was lowered after firing could be relaxed by the in-plane conductor having high ductility.
- a multilayer ceramic capacitor is disposed so as to be located at a depth of 100 m from the upper surface of the ceramic ceramic multilayer substrate, and the pyrolytic resin of Example 1 is used as an adhesion preventive material applied to the multilayer ceramic capacitor.
- paste contains hardly sinterable material (Al 2 O 3)

It was. The capacitance of each of these ceramic multilayer substrates was measured using an LCR meter in the same manner as in Example 1, and the results are shown in Table 4. Furthermore, surface-mounted components were mounted on the surface of the ceramic multilayer substrate, and the presence or absence of cracks in each ceramic multilayer substrate was observed.
