Fluidic self-assembly (FSA) using molten metal bumps is one of the most promising heterogeneous integration (HI) technologies, which enable us to integrate devices made of various materials on various substrates. We can fabricate the metal bumps using Ga having diameters of 24, 18, 12, and 8 µm with good yield. Using Ga has significant advantages; especially, it includes no toxic metals. These bumps were used for the FSA process of the metal dummy blocks having a diameter of 18 µm, and a good yield of 84% was obtained all over the substrate of about 1×1 cm2. Finally, we applied this method to the resonant tunneling diode (RTD) to verify good electrical, mechanical, and thermal contacts. The RTD device blocks having a diameter of 24 µm have been successfully assembled using the molten Ga bumps. This method is promising for high-performance RTD integration.

“…Actually, the RTDs have been successfully applied to high-frequency samplers. 19 Needless to say, a coupling circuit element having finite physical size is required to establish the mutual synchronization between two distinct oscillators. At MMW frequencies, the signal delay caused by the transmission on the coupling element cannot be neglected.…”

Summary In a system of transmission lines with regularly spaced resonant‐tunneling diodes (RTDs), where several straight RTD lines are connected halfway to a closed RTD line, a pulse‐shaped rotary traveling wave develops on the closed line by mutual synchronization of the oscillatory edge developed in each straight RTD line. The oscillating edge on each straight line is synchronized with the traveling pulse, such that the system has the potential to generate multiphase oscillatory signals in millimeter‐wave frequencies. To examine the dynamics of traveling pulses at such high frequencies, the system is modeled in the framework of the finite‐difference time‐domain method. It is found that a traveling pulse develops in the closed RTD line synchronized with the oscillatory edges moving in the straight lines, assuming a microstrip structure for each RTD line. We then compare the results of the finite‐difference time‐domain calculation with those predicted by the transmission line theory with parameter values obtained by the quasi‐transverse electromagnetic estimation. In addition, the RTD line that compactly confines the electromagnetic fields is shown to have the potential to generate multiphase oscillatory signals at submillimeter‐wave frequencies.

Abstract:A super regenerative detector employing a resonant tunneling diode (RTD) was investigated for THz wave detection. A key is to use extremely high order harmonics of the fundamental oscillation of the regenerative oscillator. This has various advantages, such as circuit simplicity, easy design, and low power consumption. The basic operation and the possibility of the THz wave detection were demonstrated by circuit simulation.
