Abstract:
1. A functional device package including: a functional device; a first Si substrate including a surface in which a plurality of concave portions are formed, wherein metallization is applied on internal surfaces of each of said concave portions; and a second Si substrate to which metallization is applied at a position opposed to the concave portions, wherein an area outside of the plural concave portions and between the plural concave portions on the surface of the first Si substrate in which the plural concave portions are formed is applied with metallization which is electrically connected to the metallization applied to the internal surfaces of each of the plural concave portions, and wherein the metallization applied to the area of the surface of the first Si substrate between the concave portions and to the internal surfaces of the concave portions formed on the first Si substrate and the metallization applied at the portions of the second Si substrate opposed to the concave portions are all connected by solder, and the first Si substrate and the second Si substrate are connected so as to hermetically seal the functional device, wherein the concave portions are formed in plurality of rows.
