摘要： A signal transmitting lead 105 is provided on an electrically insulating layer 103. Auxiliary leads 104A and 104B are provided while the auxiliary leads 104A and 104B are not in electrical contact with the signal transmitting lead 105. At least a part of the auxiliary leads 104A and 104B is covered with an electromagnetic shielding layer 106. Consequently, radiant noise from the inside or the outside of a printed wiring board can be suppressed without degrading characteristics of a signal which is transmitted through the signal transmitting lead 105.

摘要： Integrated circuits utilizing piezoelectric elements can be advantageously constructed by bonding elements together via direct bonds. Such integrated circuits include an electro-acoustic hybrid integrated circuit such as a voltage controlled oscillator wherein a semiconductor substrate having an active element is bonded through direct bonding to a surface acoustic wave resonator or a quartz oscillator as an electro-acoustic element. A quartz device can also be provided which includes a quartz plate, excitation electrodes on opposite surfaces, and a holding member made of a material having a thermal expansion coefficient substantially equal to that of the quartz plate. The holding member is connected to the quartz plate by direct bonding without using any adhesives. Because the thermal expansion coefficients of the quartz plate and the holding member are equal, no thermal stress occurs in the bonding area. As a result, virtually no stress is applied to the quartz plate and the frequency-temperature characteristic can be improved. A piezoelectric filter according to the invention includes an oscillatory piezoelectric plate made of quartz, lithium tantalate, lithium niobate or lithium borate and having an oscillatory portion; a glass plate to which the piezoelectric plate is directly bonded; and first and second oscillatory electrode members which are provided on opposite faces of the oscillatory portion, respectively, such that at least one of the oscillatory electrode members is divided into a plurality of counter electrodes.

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.
