Latest Patents

Dennis R. Sprague holds a patent for "Making hybrid IC with photoresist laminate." This patent describes a hybrid integrated circuit package and a method for fabricating the package. The package comprises a ceramic substrate with blank metallization and feedthroughs screen printed thereon. A ceramic seal ring is joined to the substrate to form the side walls of the package. The substrate metallization is plated with nickel and gold, and external leads are brazed to the ends of the feedthroughs. This design makes the package suitable for use with a wide range of different integrated circuits. The package can be adapted for specific integrated circuit functions by selectively patterning the blank substrate metallization. This is achieved by laminating a preformed piece of dry film photoresist material to the package bottom, which is then exposed through a photographic mask using a collimated light source. Dennis R. Sprague has 1 patent to his name.
