A method for wireless, noncontact testing of semiconductor wafers is presented. The technology applies to chips with active electronics, including standard integrated circuits (ICs), which require testing at the wafer level. The technology relies on short-range, near field communications to transfer data at gigabit per second rates between the probe card(More)
This paper presents a 324-element 2-D broadside array for radio astronomy instrumentation which is sensitive to two mutually orthogonal polarizations. The array is composed of cruciform units consisting of a group of four Vivaldi antennas arranged in a cross-shaped structure. The Vivaldi antenna used in this array exhibits a radiation intensity(More)
A non-contact method for parallel testing of system-in-package (SiP) assemblies is presented. This technology allows for JTAG testing of partially or fully populated SiPs in wafer form, in advance of final packaging. The technology utilizes non-contact GHz short-range, near field communications to transfer bi-directional data to SiP substrates; creating a(More)
Non-contact methods for testing system-on-chip (SoC) and system in package (SIP) assemblies are presented. This method allows for high speed testing at the wafer level for SoCs as well as testing during and after assembly for panel or wafer level SIP technologies. Wafer testing at advanced nodes is carried out without damaging underlying metallurgy - an(More)
