摘要:
A system and method are provided for testing performance characteristics of a MEMs device. The system includes an activation driver configured to receive and drive a waveform to an activation side of the micro electromechanical device and configured to provide readback of an activation voltage and activation current drawn by activation of the micro electromechanical device. The system further includes a switch driver configured to provide a load to a switch side of the micro electromechanical device and configured to provide readback of a load voltage and a load current drawn by the micro electromechanical device. It also contains a contact-closure counter. A master control card (MCC) is included to control the activation and switch drivers while a digital volt meter (DVM) is in operable communication with the micro electromechanical device to read back analog readback. An analog multiplexer is configured to provide the analog readback to a corresponding activation driver or switch driver. A computer having software configured to provide system control, data acquisition, data storage, and data analysis is in operable communication with the multiplexer, DVM and MCC

A test structure is disclosed for locating electromigration voids in a semiconductor interconnect structure having an interconnect via interconnecting a lower metallization line with an upper metallization line. In an exemplary embodiment, the test structure includes a via portion the top of the interconnect via at the upper metallization line. In addition, a line portion extends from the via portion, wherein the line portion connects to an external probing surface, in addition to a probing surface on the lower metallization line, thereby allowing the identification of any electromigration voids present in the interconnect via.
摘要:
A structure/method for reducing the stress between a dielectric, passivation layer and a metallic structure comprising coating the metallic structure with a low stress modulus buffer material, and forming the dielectric passivation layer covering the low stress modulus buffer material. The low stress modulus buffer material is composed of a layer of a polymeric material selected from at least one of the group consisting of a hydrogen/alkane SQ (SilsesQuioxane) resin, polyimide, and a polymer resin. The dielectric, passivation layer is composed of at least one layer of a material selected from at least one of the group consisting of silicon oxide and silicon nitride. A protective layer is formed over the dielectric, passivation layer. The low stress modulus buffer material has a thermal coefficient of expansion between that of the metallic structure and that of the dielectric passivation layer. In particular, the dielectric passivation layer between the metallic structure and the low stress modulus buffer material has a thermal coefficient of expansion between about 5 ppm/null C. and about 20 ppm/null C.
