Abstract: A method for measuring trace amounts of water in an atmosphere. A dry inert gas is used as the carrier gas and a dry gas comprising about 20 percent oxygen and about 80 percent inert gas is used as the reagent gas. The ionization source is operated at atmospheric pressure. A small electric field of about 200 volts per centimeter is applied across the ion drift chamber and it is biased to repel negative ions to a quadrupole mass filter. Measurements at an m/e value of 52 are integrated over a period of time. The results of the integration, when compared to a calibration chart, indicate the amount of water that had been present in the atmosphere being measured. PO9-79-016

Abstract: Sealing and stress relief are provided to a low-fracture strength glass-ceramic substrate. Hermeticity is addressed through the use of capture pads in alignment with vias and through polymeric overlayers with interconnection between the underlying via or pad metallurgy and the device, chip, wire or pin bonded to the surface of the layer. Multilevel structures are taught along with a self-aligned sealing and wiring process.
