A double barrier resonant tunneling diode (RTD) is formed and integrated with a level of CMOS / BJT / SiGe devices and circuits through processes such as metal-to-metal thermocompressional bonding, anodic bonding, eutectic bonding, plasma bonding, silicon-to-silicon bonding, silicon dioxide bonding, silicon nitride bonding and polymer bonding or plasma bonding. The electrical connections are made using conducting interconnects aligned during the bonding process. The resulting circuitry has a three-dimensional architecture. The tunneling barrier layers of the RTD are formed of high-K dielectric materials such as SiO2, Si3N4, Al2O3, Y2O3, Ta2O5, TiO2, HfO2, Pr2O3, ZrO2, or their alloys and laminates, having higher band-gaps than the material forming the quantum well, which includes Si, Ge or SiGe. The inherently fast operational speed of the RTD, combined with the 3-D integrated architecture that reduces interconnect delays, will produce ultra-fast circuits with low noise characteristics.

A gypsum board having glass fiber reinforcement. The glass fiber has sizing promoting bonding with a gypsum matrix. The glass fibers are added to the gypsum matrix cia a non-woven glass fiber mat bonded initially with a dissolvable or reversible binder to maintain the three dimensional architecture of the non-woven glass fiber mat during handling and insertion into a cast wet gypsum slurry forming a gypsum board. Upon insertion in the wet gypsum slurry, the dissolvable bond between the glass fibers in the non-woven glass fiber mat dissolves and allows the sizing coating on the glass fibers to make intimate contact with the gypsum matrix. In case of the reversible bond, the bond adhesive hydrolyzes during the gypsum board drying cycle providing intimate contact between the sizing coated glass fibers and the gypsum matrix. The non-woven glass fiber mats bonded to the gypsum matrix provides improved strength and flexure resistance of the gypsum board.
