His work has been instrumental in advancing the capabilities of hybrid microcircuit assemblies.

Latest Patents

One of Grieger's latest patents is for a large area hybrid microcircuit assembly. This invention features a ceramic substrate that includes a multiplicity of alternately screened and fired conductor and dielectric levels. Interconnections between these levels are achieved through small via holes in the dielectric layers or by means of crossovers. Thick film resistors are incorporated throughout the ceramic substrate, wherever needed, and are printed and trimmed through windows that extend through any upper layers. Additionally, resistors may be printed directly on top of the dielectric layers when necessary. Selective area hermetic sealing is utilized for chips and wire bonds that require environmental protection. This is accomplished by placing a ring frame seal around the selected area and over insulation on substrate conductors routed directly beneath the sealing area. A lid is soldered to the frame, and a proper environment is created within the sealed area before final sealing. Where equivalent chip versions of electronic components are not available, discrete components are soldered directly to the ceramic substrate outside of the sealed area. Necessary thermal dissipation is achieved by directly mounting the multilevel substrate on a heat sink.
