~ A s technology (= particle-enhanced isolation) was proposed to employ energetic proton beams on the already-manufactured mixed-mode IC wafers (prior to packaging) for the suppression of undesirable substrate coupling [I]
. However; up to this day the physics behind this proton-caused defect phase is never clear An effective I-level defict model is constructed using experimental results and existing single-trap-level theory [2] and TRIM (or SRIW [3] code-simulated parameters. The found effective single trap level (Er) is at about +0.24 eV in n-Si and at -0.34 eV in p-Si, measuring from the center of the energv band-gap.
As RF mixed-signal and patch-antenna-equipped SOC devices are becoming
the dominant products worldwide, concerns over the large real-estate
consumption by the spiral inductors (including those for microstrip antennas
and impedance-matching inductances), as well as their generally
Q-low (quality factor) performance, are now being discussed more than ever. Liao et al. have recently addressed
the Q-low issue via using location-selective proton beam bombardment,
whereby
Q-improvements of 100%–300% were evidenced. That success, nevertheless, is at times tarnished by some undesirable features, that is, the explosive rises of inductances near certain frequencies, which practically cut short the Q-enhancement and were identified to be due to resonant interactions between the inductor-propagating EM wave and the proton-caused defect dipoles. In this paper, however, the authors attempt to turn this resonance-caused undesirability to favor by proposing a new way to greatly shrink down the needed inductor size through dipoles engineering.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
