Abstract:
A system and method for the fabrication of high reliability capacitors (1011), inductors (1012), and multi-layer interconnects (1013) (including resistors (1014)) on various thin film hybrid substrate surfaces (0501) is disclosed. The disclosed method first employs a thin metal layer (0502) deposited and patterned on the substrate (0501). This thin patterned layer (0502) is used to provide both lower electrodes for capacitor structures (0603) and interconnects (0604) between upper electrode components. Next, a dielectric layer (0705) is deposited over the thin patterned layer (0502) and the dielectric layer (0705) is patterned to open contact holes (0806) to the thin patterned layer. The upper electrode layers (0907, 0908, 1009, 1010) are then deposited and patterned on top of the dielectric (0705).
Abstract:
A high frequency module is provided with a resistor array layer with interconnections, in which a plurality of resistor elements having a prescribed resistance value are formed as an array, and in which an interconnection pattern for providing electrical connection to each resistor element is formed in advance. Additionally, a capacitor array layer with interconnection in which a plurality of capacitor elements having a prescribed capacitance value are formed as an array and an interconnection pattern for providing electrical connection to each capacitor element is also formed in advance for later use. A desired circuit constant is obtained by providing interconnections among the plurality of resistor elements and among the plurality of capacitor elements, respectively, in any given combination by simply modifying the respective interconnection patterns instead of the entire module. With this configuration, a high frequency module of a more compact and lighter type which facilitates design modification is provided at a low cost.
