Abstract: A triaxial acceleration sensor which has a structure including a cover joined to a substrate including a mechanically operable functional unit to be sealed, is adapted in such a way that the joined state can be reliably obtained so as to not interfere with a displacement of the functional unit. A sealing frame is made of a heated polyimide on a periphery of an upper main surface of a substrate provided with a functional unit, and a sealing layer made of a polyimide is formed over an entire lower main surface of a cover. For integrating the substrate and the cover so as to seal the functional unit, the sealing frame and the sealing layer are joined to each other by heating and pressurizing the sealing frame and the sealing layer at a temperature that is about 50° C. to about 150° C. higher than a glass transition temperature of the polyimide while bringing the sealing frame and the sealing layer into contact with each other.

Abstract: In a method for producing an electronic component device, a heat bonding step is performed in a state in which low melting point metal layers including low melting point metals including, for example, Sn as the main component, are arranged to sandwich, in the thickness direction, a high melting point metal layer including a high melting point metal including, for example, Cu as the main component, which is the same or substantially the same as high melting point metals defining first and second conductor films to be bonded. In order to generate an intermetallic compound of the high melting point metal and the low melting point metal, the distance in which the high melting point metal is to be diffused in each of the low melting point metal layers is reduced. Thus, the time required for the diffusion is reduced, and the time required for the bonding is reduced.
