    摘要: The present invention provides multiple test structures for performing reliability and qualification tests on MEMS switch devices. A Test structure for contact and gap characteristic measurements is employed having a serpentine layout simulates rows of upper and lower actuation electrodes. A cascaded switch chain test is used to monitor process defects with large sample sizes. A ring oscillator is used to measure switch speed and switch lifetime. A resistor ladder test structure is configured having each resistor in series with a switch to be tested, and having each switch-resistor pair electrically connected in parallel. Serial/parallel test structures are proposed with MEMS switches working in tandem with switches of established technology. A shift register is used to monitor the open and close state of the MEMS switches. Pull-in voltage, drop-out voltage, activation leakage current, and switch lifetime measurements are performed using the shift register.

    摘要: A method is described for fabricating an encapsulated metal structure in a feature formed in a substrate. The sidewalls and bottom of the feature are covered by a barrier layer and the feature is filled with metal, preferably by electroplating. A recess is formed in the metal, and an additional barrier layer is deposited, covering the top surface of the metal and contacting the first barrier layer. The additional barrier layer is planarized, preferably by chemical-mechanical polishing. The method may be used in fabricating a MIM capacitor, with the encapsulated metal structure serving as the lower plate of the capacitor. A second substrate layer is deposited on the top surface of the substrate, with an opening overlying the encapsulated metal structure. A dielectric layer is deposited in the opening, covering the encapsulated metal structure at the bottom thereof. An additional layer, serving as the upper plate of the capacitor, is deposited to cover the dielectric layer and to fill the opening. The dielectric layer and the additional layer are planarized, preferably by CMP.
