  • APPARATUSES AND METHODS FOR TESTING SEMICONDUCTOR CIRCUITRY USING MICROELECTROMECHANICAL SYSTEMS SWITCHES
    Publication number: 20220373592
    Abstract: An apparatus is provided that is implemented to enable multiple tests of different types, such as a direct current (DC) test and/or a radio frequency (RF) test of a semiconductor device. The apparatus includes a microelectromechanical systems (MEMS) switch block coupled between the semiconductor device and automatic testing equipment (ATE). The apparatus is configured to enable/disable a DC path or an RF path to switch between a DC test and an RF test without reconfiguring the connections between the semiconductor device and the ATE. The DC path is used to perform a DC contact test for one or more pins of the semiconductor device. The RF path is used to perform an RF test for the semiconductor device.

  • Method of and apparatus for protecting a switch, such as a MEMS switch, and to a MEMS switch including such a protection apparatus
    Patent number: 10855073
    Abstract: A method of and apparatus for protecting a MEMS switch is provided. The method and apparatus improve the integrity of MEMS switches by reducing their vulnerability to current flow through them during switching of the MEMS switch between on and off or vice versa. The protection circuit provides for a parallel path, known as a shunt, around the MEMS component. However, components within the shunt circuit can themselves be removed from the shunt when they are not required. This improves the electrical performance of the shunt when the switch is supposed to be in an off state.
