Mechanical Properties Measurements of 0.35-µm BiCMOS MEMS Structures

Liu J., Fedder G.K., Sassolini S., Sarkar N., Carnegie Mellon University, US

A new Young’s modulus test structure has been designed and used in our lab. Simple models have been built in simulating lateral and vertical stress gradients. Test structures, measurements and FEA simulations are reported on [...]

Modeling Electrothermal Plastic Deformation

Geisberger A., Sarkar N., Ellis M., Skidmore G., Zyvex Corporation, US

Self-assembly of three-dimensional microstructures has been achieved using EPDA (Electrothermal Plastic Deformation Assembly). The EPDA process, in this case, is dependent on gold yielding within a gold and polysilicon bimorph. To plastically deform the bimorph [...]
