    摘要: A semiconductor device for life enhancement of electrical connections between a semiconductor chip and a mounting substrate. Protruding electrodes, each including a bump electrode and a land electrode, are located on the lower surface of an LSI chip. The bump electrodes are substantially spherical and have a first thickness. Connecting terminals of substantially spherical configuration and having a second thickness are directly connected to corresponding land electrodes by melting. Connecting patterns are located on the upper surface of a wiring board which is larger in area than the LSI chip in plan configuration, and external electrodes, each including a connecting pattern and an external electrode, are located on the lower surface of the wiring board. The external electrodes are substantially spherical and have a third thickness. The connecting patterns are directly connected to corresponding connecting terminals, respectively, by melting.

    摘要: The following steps are performed when processing electronic components such as piezoelectric devices. At Step 1 inter-atom bond is created between a functional member such as a quartz crystal plate and a first substrate, and the functional member and the quartz crystal plate are directly joined together. At Step 2, the functional member and a second substrate are fixed together with an adhesive agent or by a direct bond. At Step 3, the first substrate is removed chemically or mechanically, with said functional member and said second substrate still being joined together. A step of polishing said functional member for the adjustment of thickness thereof may be done between Step 1 and Step 2. For example, a silicon dioxide thin film may be provided between the functional member and the first substrate. Since no adhesive layer exists between the functional member and the first substrate, this improves the degree of plane of the functional member when joined to the first substrate. Therefore, functional member thickness accuracy becomes extremely high and mass productivity is also improved.
