FinFET has become the mainstream logic device architecture in recent technology nodes due to its superior electrostatic and leakage control [1,2,3,4]. However, parasitic capacitance has been a key performance detractor in 3D FinFETs. In this work, a novel low temperature ALD-based SiBCN material has been identified, with an optimized spacer RIE process developed to preserve the low-k value and provide...
In0.53Ga0.47As channel MOSFETs were fabricated on 300 mm Si substrate. The epitaxial In0.53Ga0.47As channel layer exhibits high Hall electron mobility comparable to those grown on lattice matched InP substrates. Excellent device characteristics (SS∼95 mV/dec., Ion/Ioff ∼105, DIBL ∼51 mV/V at Vds = 0.5V for Lg=150 nm device) with good uniformity across the wafer were demonstrated. The extracted high...
This paper reports the first MEMS device designed for in vitro measuring of electroisletogram (EIG) of individual rat islets. Using vacuum to hold an islet in proximity to a microelectrode, strong EIG signals in millivolt range are obtained, while the noise is about 100µV pk-pk. This work proves the feasibility of using MEMS and EIG for high-throughput screening, in contrast to patch-clamp measurements,...

By using sidewall electrode technology, both record small functional TiO2 selection device (1 × 5 nm2) and HfO2 based RRAM device (1 × 3 nm2) were for the first time successfully demonstrated in this work, improving the understanding of the switching mechanism in an ultra-small, functional resistive random access memory (RRAM) device. The tunneling based low temperature back-end selection devices...
Low-speed direct-drive gearless machines are highly desirable for electric vehicle/hybrid electric vehicle (EV/HEV) propulsion due to the elimination of the associated gear wear, oil maintenance and acoustic problems. Conventional gearless direct-drive permanent magnet (PM) machines generally suffer from heavy weight, structural bulkiness, and lubrication problems. Due to the “magnetic-gearing” effect,...
Memory motors [1] [2] equipped with either single low-coercive force (LCF) or hybrid magnets have been extensively investigated due to the elimination of the associated excitation loss during the flux adjustment. Thus, they enable high efficiency operation within a wide range of speeds and loads. Very recently, switched-flux topologies that feature high torque density, simple rotor, and expedient...
Nowadays, numerous electrical machine topologies have been proposed and extensively investigated, which can extend the operating speed range together with the improvement of flux weakening capability without scarifying high efficiency. Amongst these machine topologies, variable-flux permanent magnet machines (VFPMs) are a competent candidate for electric vehicle/hybrid electric vehicle (EV/HEV) propulsion.
Traditional direct-drive permanent magnet synchronous machine (PMSM) suffers from large bulk and complex topology structure [1], which extremely limits its industrial applications. As a novel embranchment of PMSM, PM vernier machine (PMVM) incorporates the magnetic gear effects into conventional PMSM producing high torque at a relatively low speed, which is desirable for direct-drive applications...
The linear-rotary permanent magnet actuator (LRPMA) has been widely used in industrial manufacturing, automation control field and so on. The mover of developed LRPMA needs a lot of NdFeB material with the Halbach structure. In order to decrease the amout of NdFeB, a novel LRPMA is proposed using interlaced poles, namely, permanent magnet (PM) poles and iron poles, as shown in Fig.1 (a), (b). The...
Pole-changing permanent magnet (PM) machines, which can offer wide operating speed range, have attracted global attention in industry application [1-3]. However, the previous pole-changing PM machines adopting distributed winding, suffer from lengthy end winding and relatively low efficiency. Therefore, this paper presents a new variable flux pole-changing PM memory machine (VF-PCPMMM) employing fractional...
Transverse flux permanent magnet generator (TFPMG) has attracted a great attention for the large torque and high efficiency at low speed, as well as the prominent capability of carrying considerable pole numbers [1]. Many new TFPMGs with attractive structures have been proposed such as a novel flux switching transverse flux PM generator (FS-TFPMG) presented to improve the stator space utilization...
The interface magnetic phenomenon, which forms the backbone of modern information technology, is of great interest for several decades. When two or more dissimilar materials with different long-range magnetic orderings and/or functionalities are combined together, it may give rise to new interfacial properties, such as the proximity effect [1]. The exchange coupling between two FM layers, as well...
Transverse flux permanent magnet generator (TFPMG) is especially suitable for wind power application for the merits of large pole numbers, decoupled magnetic circuit, and high power density. The distinguishing feature of TFPMG is the magnetic flux existed in three-dimensional space and three-dimensional finite element method (3-D FEM) is employed to analyze its characteristics. Such as flux-switching...

For the high-power module applications, direct-plated-copper (DPC) aluminum nitride (AlN) substrate with a high thermal conductivity provide a good alternative to conventional aluminum oxide (Al2O3) substrate for better heat dissipation. However, the DPC AlN substrate suffers the delamination failures between Cu film and AlN substrate during thermal cycling, due to the higher thermal expansion coefficient...
Owing to NAND flash technology facing its scaling limit, resistive random access memory (RRAM) with simple film stack and no cross coupling issue between cells is a promising candidate for future high density memory application [1,2]. The 1TnR architecture with 3D vertical RRAM (VRRAM) structure realizes ultra-low bit cost for high compact density array [3,4]. However, this novel 1TnR structure and...
We examine electromigration mass transport under pulsed-DC (PDC) and AC conditions by measuring the Cu drift velocity. We observed drift velocities that are constant as a function of duty ratio, confirm that there is no recovery of electromigration damage during current reversal, or off-cycles. Failure time distributions under PDC conditions can be accurately modeled by a void growth mechanism with...
