摘要： The present invention generally relates to a method of operating a MEMS DVC while minimizing impact of the MEMS device on contact surfaces. By reducing the drive voltage upon the pull-in movement of the MEMS device, the acceleration of the MEMS device towards the contact surface is reduced and thus, the impact velocity is reduced and less damage of the MEMS DVC device occurs.

摘要： The present invention generally relates to a method for forming a MEMS device and a MEMS device formed by the method. When forming the MEMS device, sacrificial material is deposited around the switching element within the cavity body. The sacrificial material is eventually removed to free the switching element in the cavity. The switching element has a thin dielectric layer thereover to prevent etchant interaction with the conductive material of the switching element. During fabrication, the dielectric layer is deposited over the sacrificial material. To ensure good adhesion between the dielectric layer and the sacrificial material, a silicon rich silicon oxide layer is deposited onto the sacrificial material before depositing the dielectric layer thereon.

摘要： The present invention generally relates to a MEMS DVC having a shielding electrode structure between the RF electrode and one or more other electrodes that cause a plate to move. The shielding electrode structure may be grounded and, in essence, block or shield the RF electrode from the one or more electrodes that cause the plate to move. By shielding the RF electrode, coupling of the RF electrode to the one or more electrodes that cause the plate to move is reduced and capacitance modulation is reduced or even eliminated.

摘要： The present invention generally relates to cellular phones having multiple antennas. The invention relates to how two antennas in a diversity or MIMO antenna system interact through mutual coupling. The mutual coupling is due to proximity of the two antennas, their antenna pattern and efficiency. The performance of the system can be optimized by adjusting the mutual coupling between the antennas. The primary and secondary antennas can be “tuned” and “de-tuned” respectively to enhance system performance. In this invention, the primary and secondary antennas are tuned independently using MEMS capacitor configured in the antenna aperture for frequency tuning.

摘要： The present invention generally relates to a MEMS digital variable capacitor (DVC) (900) and a method for manufacture thereof. The movable plate (938) within a MEMS DVC should have the same stress level to ensure proper operation of the MEMS DVC. To obtain the same stress level, the movable plate is decoupled from CMOS ground during fabrication. The movable plate is only electrically coupled to CMOS ground after the plate has been completely formed. The coupling occurs by using the same layer (948) that forms the pull-up electrode as the layer that electrically couples the movable plate to CMOS ground. As the same layer couples the movable plate to CMOS ground and also provides the pull-up electrode for the MEMS DVC, the deposition occurs in the same processing step. By electrically coupling the movable plate to CMOS ground after formation, the stress in each of the layers of the movable plate can be substantially identical.
摘要翻译：本发明一般涉及一种MEMS数字可变电容器（DVC）（900）及其制造方法。 MEMS DVC内的可移动板（938）应具有相同的应力水平，以确保MEMS DVC的正常工作。为了获得相同的应力水平，在制造过程中可移动板与CMOS接地分离。在板已经完全形成之后，可移动板仅电连接到CMOS接地。通过使用形成上拉电极的相同层（948）作为将可移动板电耦合到CMOS地的层而发生耦合。由于相同的层将可移动板耦合到CMOS地，并且还为MEMS DVC提供上拉电极，所以沉积在相同的处理步骤中发生。通过在形成后将可动板电耦合到CMOS地，可移动板的每个层中的应力可以是基本相同的。
