This paper presents, for the first time, the thermo-mechanical reliability and the electrical performance of 30μm through package vias (TPVs) formed by Corning in ultra-thin low-cost bare glass interposers and metallized directly by sputter seed and electroplating. In contrast to glass interposers with polymer coated glass cores reported previously, this paper reports on direct metallization of thin and uncoated glass panels with fine pitch TPVs. The scalability of the unit processes to large panel sizes is expected to result in bare glass interposers at 2 to 10 times lower cost than silicon interposers fabricated using back end of line (BEOL) wafer processes. The thermo-mechanical reliability of 30μm TPVs was studied by conducting accelerated thermal cycling tests (TCT), with most via chains passing 1000 cycles from −55°C to 125°C. The high-frequency behavior of the TPVs was characterized by modeling, design and measurement up to 30 GHz.

The Stability

The stability of the coating is investigated. For the hydrothermal ageing, the result of ageing of glass fiber compatible to resin with ageing of coating, it is obvious to find out that the effect of ageing of glass fiber/resin composite to IFSS is more than ageing of coating. The composites have more depressed. When the coating degraded completely, the IFSS is near to the value of bare glass fiber. Ageing in the different time with different temperature showed that ageing of micro-composite was dependent on this compatible matrix. However, ageing of coating was dependent on its structure.

ABSTRACTThe microstructure of CdTe sources grown on bare 7059 and SnO2-coated 7059 glass substrates used in the close-space sublimation (CSS) growth of CdTe films, is affected by nucleation conditions during their fabrication. For CdTe sources grown on bare glass substrates, denser source microstructures with smaller grains are promoted by low-temperature nucleation conditions. Growth rates of CdTe films deposited using these source plates are inversely proportional to the packing density of the grains. CdTe sources grown on glass undergo significant texture changes during their use in subsequent CSS deposition. CdTe sources grown on SnO2-coated glass substrates exhibit dense structures both with and without low-temperature nucleation and increased grain size with low-temperature nucleation. These source plates show less texture change associated with thermal annealing than their bare-glass counterparts, however, they are much more susceptible to CdO formation during subsequent CSS deposition processes in which oxygen is present. Source oxidation results in a decrease of the (111)/(220) x-ray diffraction intensity. Analysis of the (111)/(220) intensity ratio with and without source oxidation suggests the preferential formation of CdO on the (111) planes. In general, source oxidation appears to be a inversely proportional to the grain size of the source material.
