Abstract:
It is an object of the invention to provide an electronic device in which a passive element with an excellent element characteristic is embedded and a method of manufacturing the same. It is another object of the invention to provide an electronic device which makes miniaturization thereof possible and a method of manufacturing the same. A body (10) and a functional block (30) are stuck together by accommodating the functional block (30) in an opening of green ceramic sheets and then sintering those sheets. A temperature for sintering sheets to constitute a dielectric portion (31) of the functional block (30) can be different from that for sintering a raw material of a ceramic material to constitute a dielectric portion (12) of the body (10). Flexibility in selecting a material of the dielectric portion (31) can be extended and a material with a low dielectric constant can be selected for the dielectric portion (31). A dielectric constant of the ceramic material of the functional block (30) can be higher to realize miniaturization of the functional block (30). Since conductor patterns of the functional block (30) can be formed by means of thin film technologies, a three-dimensional appearance is given to edges of the conductor patterns, thereby the functional block (30) with a high Q-value can be embedded in the body (10).
Abstract:
A thin-film metal resistor (44) suitable for a multilayer printed circuit board (12), and a method for its fabrication. The resistor (44) generally has a multilayer construction, with the individual layers (34, 38) of the resistor (44) being self-aligned with each other so that a negative mutual inductance is produced that very nearly cancels out the self-inductance of each resistor layer (34, 38). As a result, the resistor (44) has a very low net parasitic inductance. In addition, the multilayer construction of the resistor (44) reduces the area of the circuit board (12) required to accommodate the resistor (44), and as a result reduces the problem of parasitic interactions with other circuit elements on other layers of the circuit board (12).
Abstract:
A low-EMI circuit which realizes a high mounting density by converting the potential fluctuation of a power supply layer with respect to a ground layer which occurs on switching an IC device etc., into Joule's heat in the substrate without using any parts as a countermeasure against the EMI. Its structure, a circuit board using it, and a method of manufacturing the circuit board are also disclosed. Parallel plate lines in which the Q-value of the stray capacitance between solid layers viewed from the power supply layer and ground layer is equivalently reduced and which are matchedly terminated by forming a structure in which a resistor (resistor layer) and another ground layer are provided in addition to the power supply layer and the ground layer on a multilayered circuit board. A closed shield structure is also disclosed. This invention can remarkably suppress unwanted radiation by absorbing the potential fluctuation (resonance) which occurs in a power supply loop by equivalently reducing the Q-value of the stray capacitance, absorbing the standing wave by the parallel plate lines matchedly terminated and, closing and shielding the parallel plate lines.
