Acoustic concentration of micro/nanoparticles and cells on low-cost periodic patterned chips by operating over a wide frequency range.
Phononic crystals (PnCs) have been used to boost the quality factor (Q) of AlN-on-Silicon Lamb Wave Resonators (LWRs). But most reports on applying PnCs resonators focused common <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$< 110>$ </tex-math></inline-formula> orientation within (100) silicon. Little is known applicability other crystal orientations. In this work, we explore effect acoustic band...
Buried layers are used in bipolar devices to lower collector resistance bulk silicon and SOI (silicon-on-insulator) technologies. They also with deep trench for isolating different types. This work investigates the effect of buried layer processing on CMOS capacitor reliability, comparing results between substrates. Opposing from technologies indicate degradation mechanisms at play. The starting material requires that metal contaminant gettering be taken account layers.
We demonstrate the boosting of quality factor (Q) a <100> aligned Aluminum Nitride (AlN) on Silicon (Si) laterally vibrating resonator (LVR) by using wide acoustic bandgap (ABG) phononic crystal (PnC) anchors. To date, Q-boosting strategies have been studied predominantly for common <110> orientation. Given anisotropy Si, changing orientation could notably affect effectiveness strategies. show experimentally that Qs LVRs more than doubled to 10000 with PnC further corroborate PnCs, we also...
Acoustofluidic platforms typically enable only rectangular matrix-like of particle patterns in a closed microchamber actuated by surface acoustic wave (SAW) device. More complex and unique require sophisticated dedicated SAW transducer. As first, we demonstrate the generation ring-shape on-chip simple generic The ability to reshape field is realized using bulk micromachined microelectromechanical systems (MEMS) chip. We also show for first time creation two-dimensional (2D) pattern with just...
In this paper, a novel structure named as quasidouble silicon-on-insulator metal-oxide-semiconductor transistor (SOI MOSFET) is proposed. Compared with the of normal SOI MOSFET, ultrathin oxide layers and p+ wells are added under source drain regions, which successfully isolate from buried (BOX). The prevent leakage current back gate enhance its reliability. And P+ acting body ties suppress floating effect, but also decrease resistance contact. Transfer characteristic curve, output curve...
As a basic logic unit of integrated circuit, the stability parameters inverter have direct effect on performance system. This paper starts from parametric drift traditional caused by variation threshold voltage MOSFET. Then new drift-resistant is proposed. structure utilizes compensation circuit to solve such as decrease low level noise margin and high output, transfer characteristic curve. Finally, Cadence utilized verify validity this generalized NAND gate its drift.
From the varying threshold voltage of MOSFET caused by external factor, this paper analyzes variation tendency amplifier's gain. It makes clear how gain three different amplifiers changes in theoretical. After that, EDA tools are utilized to verify theoretical calculation. The and simulation result show that voltage(Vth) is a sensitive parameter In specific range, amplifier will becomes smaller with decreasing Vth input transistor.
Abstract Plug-and-play acoustofluidic devices are highly promising for dexterously aggregating microparticles owing to the advantages of being contactless, label-free, and cost-efficient. Despite extensive progress, existing largely limited addressing a single sample per device, lacking ability address multiple samples high-throughput operations in device. In this work, we report multi-sample aggregation device that enables manipulation up 12 simultaneously using reusable acoustic tweezer....

Phononic crystals (PnC) can help shape acoustic fields to enhance microfluidic functions in acoustofluidic devices. But operating within the defined phononic band gap (PBG) limits scope for optimizing functions. We show, first-time, efficient droplet centrifugation that works outside range of PBG. Instead using deep reactive ion etching (DRIE) create PnC, we here use laser machining with aim demonstrate low cost and rapid prototyping complex superstrates particle concentration greatly. The...
