The decomposition characteristics of poly(propylene carbonate) containing a photoacid generator have been studied. The influence of casting solvent, photoacid concentration and type, UV exposure dose, substrate surface, and ambient gas were included

Incorporation of copper ions into poly(propylene carbonate) (PPC) films cast from γ-butyrolactone (GBL), trichloroethylene (TCE) or methylene chloride (MeCl) solutions containing a photo-acid generator is shown to stabilize the PPC from thermal deco

The fabrication of low-loss transmission line structures with an air dielectric layer is described. The channels are characterized at low frequency (10 and 100 kHz) using capacitance and loss tangent and at high frequency (500 MHz to 10 GHz) using -p

A copper-to-copper bonding process was developed for an all- copper, chip-to-substrate interconnect technology. High aspect ratio, polymer molds for electroplating were formed using a photodefinable polymer on both the chip and the substrate surfaces

Chip-to-chip communication across conventional printed circuit boards is limited to low frequencies (a few GHz), thus limiting the aggregate bandwidth without the use of optics. Low-loss, air insulated transmission lines can extend the frequency rang

We present a novel CMOS compatible approach to fabricate on-chip microfluidic cooling channels using a spin-on sacrificial polymer material at wafer level. Deep trenches (>100 /spl mu/m) etched into the backside of an IC wafer were successfully fille
