Thermomechanical Properties of Elastomeric Stamps for Micro-Transfer Printing Applications

C. Reyes1, K. Oswalt 1, J. Thostenson1, J. Roe1, D. Gomez1
1X-Celeprint, Durham, NC, USA

Micro-transfer printing (MTP) enables mass-transfer of wafer-level chips having lateral dimensions ranging from 3 x 7 um to 650 x 650 um to a nonnative substrate. This is accomplished with an elastomeric stamp containing micrometer scale posts that have been precisely defined using ... En savoir plus

Silicon Nitride Corrugated Membrane with High-Width-Aspect-Ratio for MEMS Microphones

Shubham1
1Knowles Electronics, Itasca, IL, USA

Micro-Electro-Mechanical Devices such as acoustics sensors, finger print sensors, tunable capacitors etc. are widely used in commercial applications. The pressure sensors use membranes which deflect upon applied pressure load. The most important aspect of any pressure sensor is its ... En savoir plus
