In this paper, the change in partial discharge resistance of low density polyethylene and epoxy resin irradiated with γ-ray at high dose rate has been investigated. The samples were irradiated in air up to 100 kGy then up to 1000 kGy by means of a 60Co γ-source at a dose rate of 10 kGy/h. By applying an AC voltage of 8 kHz between a pair of needle-plane electrode, partial discharge was generated to...
We present a simple and low-cost fabrication process for microcantilevers from both pure Polymethylmethacrylate (PMMA) and magnetic PMMA composites with maghemite nanoparticle concentrations up to 3 vol.% (12 wt.%). The fabricated cantilevers have lengths of 30 – 300 µm, widths of 14 µm and a thickness of 3 µm. The presented fabrication process consists of structural layer patterning by hot embossing,...
Electro-optical composites based on the product of electro-strictive and elasto-optical effects were developed. Laminate composites of PbZr1-xTixO3 and Polycarbonate were synthesized. Their electro-optical properties were studied. The nominal transverse electro-optical coefficient of the composites was observed 3 times larger than the similar quantity of NbLiO3. Experiments and theoretical analysis...
By the product of magnetostriction and stress-birefringence, the laminate composites that can show Voigt effect was suggested and fabricated. Under a magnetic field no stronger than 1900 Oe, a phase difference of about 3.3π was observed for a trilayer composite Tb1-xDyxFe2-y / polycarbonate / Tb1-xDyxFe2-y with the polycarbonate layer in size of 5×2.75×20 mm3 at room temperature, resulting in a half-wave...
The 3 D interconnect technology with Thru Silicon Via (TSV) have gained tremendous advancement in recent years. Final adoption of TSV technologies requires a robust and cost competitive TSV processes. Sidewall plated TSV with polymer filling can reduce half of total process steps from TSV copper (Cu) seed deposition to front-via1 expose. TSV plating time can be reduced ~ 60% for sidewall plated TSV...
The first electrochemical actuator with a parylene bellows for intraocular drug delivery is presented in which the bellows separates the electrolysis actuation chamber from the drug reservoir. The parylene bellows was fabricated using a novel polyethylene glycol (PEG)-molding process and mechanically characterized. Optimization of the gas generation efficiency of the actuators was performed. We achieved...
The advances of semiconductor technology are mainly due to the advances of polymeric materials. These include the use of polymers as adhesives (both conductive and non-conductive), interlayer dielectrics (low-k, low loss dielectrics), encapsulants (discrete and wafer level packaging), embedded passives (high-k and high-Q materials), superhydrophobic self-cleaning lotus effect surfaces, and etc. In...
