Latest Patents
Froot's latest patents include innovative methods for the fabrication of semiconductor modules with ceramic substrates. One of his patents addresses the detection of residual glass that can appear at semiconductor chip pads and via holes during the fabrication of alumina/glass ceramic substrates. In this process, the glass used for forming the ceramic substrates is doped with a rare earth oxide. The ceramic structures are then irradiated after firing with radiation of wavelengths in the range of 350-500 nanometers to induce fluorescence in the glass. This technique allows for the identification of any residual glass on the surface of the metallic interconnector pads, enabling rework or scrapping of parts as necessary.
Another significant patent involves microanalysis by pulse laser emission spectroscopy. This system is designed to detect and identify the composition of materials, such as semiconductor wafers and chips, during various stages of processing. The material is laser irradiated to induce molecular fluorescence, and the decay rate of this fluorescence is measured. This decay rate is then compared with a record of acceptable modifications of the material, including any contaminants or impurities, to determine the state of the material's modification.
