  • Patent number: 10782339
    Abstract: Automatic test equipment with multiple components to generate highly accurate and stable analog test signals and method for operating the test system in semiconductor manufacturing process are disclosed. Output analog signals from existing test systems often fail the stability and accuracy requirement with less than 10 mV variations for testing certain electronic devices, due in part to environmental condition variations such as temperature fluctuations. Traditional compensation mechanisms for temperature variations involve time consuming and disruptive calibration procedures. Disclosed here is a system and method that provides near real-time monitoring and compensation for temperature-induced variations via a digital control mechanism that compensates for environmental variations in a time scale of less than 10 milliseconds and maintains the AC output analog signal with 10 milliVolt accuracy.

  • Patent number: 10734332
    Abstract: In conventional packaging strategies for mm wave applications, the size of the package is dictated by the antenna size, which is often much larger than the RFIC (radio frequency integrated circuit). Also, the operations are often limited to a single frequency which limits their utility. In addition, multiple addition build-up layers are required to provide the necessary separation between the antennas and ground layers. To address these issues, it is proposed to provide a device that includes an antenna package, an RFIC package, and an interconnect assembly between the antenna and the RFIC packages. The interconnect assembly may comprise a plurality of interconnects with high aspect ratios and configured to connect one or more antennas of the antenna package with an RFIC of the RFIC package.

  • Patent number: 10651080
    Abstract: Thin AlN films are oxidatively treated in a plasma to form AlO and AlON films without causing damage to underlying layers of a partially fabricated semiconductor device (e.g., to underlying metal and/or dielectric layers). The resulting AlO and AlON films are characterized by improved leakage current compared to the AlN film and are suitable for use as etch stop layers. The oxidative treatment involves contacting the substrate having an exposed AlN layer with a plasma formed in a process gas comprising an oxygen-containing gas and a hydrogen-containing gas. In some implementations oxidative treatment is performed with a plasma formed in a process gas including CO2 as an oxygen-containing gas, H2 as a hydrogen-containing gas, and further including a diluent gas. The use of a hydrogen-containing gas in the plasma eliminates the oxidative damage to the underlying layers.
