An All-in-One Testing Chip for the Simultaneous Measurement of Multiple Thermoelectric Parameters in Doped Polysilicon [PDF]

Micromachines
Polysilicon is widely used as a thermoelectric material due to its CMOS compatibility and tunability through doping. The accurate measurement of the thermoelectric parameters—such as the Seebeck coefficient, thermal conductivity, and electrical ...

Disclosing the Polysilicon Deposition Process [PDF]

, 2010
The chemical route for producing hyperpure silicon, referred to as polysilicon, is energy intensive. In this work two paths are analysed to reduce energy consumption during polysilicon deposition: reduce power loss and increase polysilicon productivity.

The Effect of Defect Charge and Parasitic Surface Conductance on Aluminum Nitride RF Filter Circuit Loss

Micromachines, 2023
When AlN thin films are deposited directly on the high-resistance silicon (HR-Si) substrate, a conductive layer will be formed on the HR-Si surface. This phenomenon is called the parasitic surface conduction (PSC) effect.

MEMS Reliability: On-Chip Testing for the Characterization of the Out-of-Plane Polysilicon Strength

Micromachines, 2023
Polycrystalline silicon is a brittle material, and its strength results are stochastically linked to microscale (or even nanoscale) defects, possibly dependent on the grain size and morphology. In this paper, we focus on the out-of-plane tensile strength
