We introduce a new Periodic micro coaxial transmission line (PMTL) that is capable of sustaining a TEM propagation mode up to THz band. The PMTL can be manufactured using the current photolithographic processes. This transmission line can be embedded in microscopic layers that allow many new applications. We use the PMTL to develop a wideband highly scalable connector that is then used in a Probe that can be used for connecting to microscopic scale Integrated Circuits with picoseconds High Speed Digital and near THz Analogue performance in various stages of development from R&D to production testing. These probes, in one embodiment, provide a thin pen-like vertical probe tip that matches the die pad pattern precisely that can be as agile as a high speed plotter pen, connecting on the fly to any die pattern on a wafer. This approach allows the most valuable part of the test, namely the wafer to remain stationary and safe, and the least costly part of the test, namely the probe to take most of the wear and tear. We further use the embedded PMTL to develop a modular, scaleable and fully automated Universal Test Fixture for testing chips in various stages of development mainly for digital IC chips that can be utilized in production lines with pick and place of chips on tape to test every chip before insertion into circuits. One embodiment includes a low profile wideband Signal Launcher and an alligator type RF Clip that can be used at the edge of PCB's directly for validation broads. The Signal Launcher is used to develop a new versatile Flush Top Test Fixtures for individual device testing in various stages of development from die, to packaged, to Module, to Circuit Boards. The PMTL can also provide Confined Field Interconnects (CFI) between various elements on semiconductor wafers to reduce parasitic and radiation losses and practically eliminating cross talk, thus, increasing the speed of digital IC's. The PMTL is also used to develop a Universal Test Socket, and a Hand Probe with performance up to 220 GHz.
