METHOD FOR FABRICATING CERAMIC PACKAGE HAVING CAVITY AND CERAMIC PACKAGE OBTAINED THEREBY AND CERAMIC PACKAGE FABRICATED THEREBY

摘要

The present invention relates to a ceramic package. Preparing a green sheet having a plurality of desired specifications; And pressing the green sheets of the same type as each suhyo necessary to form a multiple layer structure; By punching the central portion of some of the green sheet into a predetermined size to form a central opening through which the cavity; Laminating the structure layer in packages having the cavity between the upper and lower jigs, and each insert a cavity plate having at least the same aperture and the cavity between the structure layer and the upper and lower jigs, and; Applying a predetermined pressure to the pressing jig and the structure layer; It is prepared by sintering the pressed structure layer at a predetermined temperature. By compression bonding of the entire layer structure in the cavity plate is placed between upper and lower jig and the whole layer structure state, the upper base layer in the cavity to avoid the phenomenon of deultteuneun camber.
