Example 1 Ceramic green sheets of various thicknesses made of 94% alumina were prepared by a doctor blade method. A hole for taking out an electrode was formed in a green sheet A having a thickness of 0.3 mm, and a conductive paste (tungsten) was printed to form a through-hole electrode and a wiring electrode.
This through-hole electrode is located at a position divided by a break groove to be formed later. Drill a square hole in the component mounting part on a 0.2 mm thick green sheet B, drill a hole for an electrode,
The conductive paste was printed to form through-hole electrodes and wiring electrodes. A square hole to be an opening 3 for mounting a component was formed in a green sheet C having a thickness of 0.4 mm. Green sheet A, green sheet B and green sheet C were aligned and arranged, and heated and pressed to form a laminate having a three-layer structure. A paste of tungsten as a band-shaped metallization layer is printed and coated around the upper surface of the opening peripheral portion 4 around the opening of the laminate, and dried. Then, a tungsten paste was printed and applied to the upper part of the metallized layer in a narrower band, and then dried to form a three-step metallized layer having a step shape. Since a large number of individual packages were formed on the laminate having the metallized layer formed thereon, a plurality of vertical and horizontal break grooves 10 were formed for division at a depth of 0.3 mm from one surface on the metallized layer side. This laminate was sintered in a hydrogen atmosphere in a nitrogen atmosphere furnace at a temperature of 1650 ° C. to produce a ceramic substrate 1 having a metallized layer thickness of about 20 μm. Further, electrolytic Ni plating having a thickness of about 8 μm (electroless Ni plating) was applied to the metallized layer and the wiring electrodes. The metallized layer 5 formed on the periphery of the opening is metallized by plating.
It is called a plating layer 6.

A photoresist film is adhered to the surface of Kovar on a ceramic substrate to which Kovar is welded, exposed with a pattern film, developed to remove portions corresponding to break grooves, and further exposed to Kovar exposed from the photoresist. The portion was etched, and Kovar was removed so that the break grooves could be visually observed. A quartz resonator was manufactured by dividing a component along a break groove previously formed on a ceramic base and using an electronic component package on which components were mounted.

The electronic component package manufactured in this manner is formed in a step-like manner without increasing the temperature of the crystal unit because the Kovar 2 and the metallized plating layer 6 are welded by irradiation with an electron beam. In addition, the metallized / plated layers of multiple stages absorb thermal shock, do not cause cracks, and have excellent hermetic sealing properties that do not cause peeling in the metalized layers, plated layers, and Kovar.

(Example 2) The procedure was substantially the same as that of Example 1 except that welding and sealing were performed by irradiating a laser beam instead of an electron beam.

According to the present invention, a ceramic base electronic component package having a metallized plating layer formed by forming a plurality of metallized layers in a stepwise manner at the periphery of an opening made of ceramic and applying metal plating to the metallized layer, and its manufacture. Method
And a package for electronic components in which a metal lid is placed in contact and the lid and a metallized plating layer are welded by irradiation with an electron beam or a laser, without increasing the temperature of the electronic components mounted inside the package. Since the metallized / plated layers formed on the base made of multiple layers act as a buffer for thermal shock, there is no cracking, and there is no peeling in the metallized layer, plated layer, etc. An electronic component package and a method for manufacturing the same can be provided.
