The stand-by current (Isb) performance is impacted by the failure of Cu interconnects due to Cu extrusion forming Cu-loss. This paper provides the solution to overcome the formation of Cu-loss without modifying via etching reactant to keep the capability of via etching tuning. Cu-loss strongly depends on the existence of Cu-F produced by via etching process. By inserting the NH3 flush step, Cu-F is completely removed. Moreover, 5 times the queue time extension is achieved. The Isb failure by Cu-loss is obviously exterminated.

The system is provided with humanized user interface and the function of facial recognition, which was completed through the cooperation with the Department of Special Education. In order to design and produce Jacky, this system (Figure 3), by ourselves, we actually found out the situation and needs of children with special education. The main function of Jacky (intelligent robot) is to track the face of subject target and then rating how much the subject pay attention to class. we had already finished the commissioning of the system on 9 subject respectively belong to 4 elementary schools, and this research had won the first place of Bio-Medical Electronics Education Consortium 2016 competition. Hope that this research would provide positive effects to autistic children, and help special education teachers on teaching further.

This paper presents an 11-bit 250MS/s subrange SAR ADC. The subrange SAR ADC in this paper consists of coarse conversions of 4-bit flash ADC and fine conversions of 8-bit SAR ADC, which fully combines high speed of flash ADC and low power consumption of SAR ADC. The design is fabricated in a 40nm low-leakage process, and the core area is 0.018mm2. The post layout simulation achieves an ENOB of 9.99 bits at Nyquist input and consumes 1.5mW from 1.1V supply, leading to a FOM of 5.86fJ/conv-step.

The Surface Acoustic Wave (SAW) sensor technology using piezoelectric material and surface interdigital electrodes are realized as a 2-port oscillator. To improve the selectivity and sensitivity, three polymers are individually coated onto the SAW oscillators to detect organic vapors. The vapor-sensing capability is evaluated based on a 4-SAW array scheme wherein four kinds of flammable vapor like propylene, ether, butanone and benzene are under tested with polymer films including poly-vinylphenol (PVP), polystyrene (PS) and Ethyl Carbamate (EC). After obtaining the experimental result of vapor sensing, the fingerprint of their sensing characteristics can be successfully demonstrated for vapor recognition application.

This study introduces an innovative multi-chip white LED (MCW-LEDs) that exploits a newly synthesized compound combining red Y2O3:Eu3+ with the in-cup phosphor package. The principal advantages of this solution is to enhance the color rendering index (CRI) of MCW-LEDs that have the correlated color temperature of 8500 K to a greater value than 84. In addition, impact of this red-color-adding approach on the light attenuation through silicone lens is also demonstrated using Beer-Lambert law.

The hardware aims to provide a robust solution for the extraction of complementary imperceptible structured light method. For solving the complicated synchronizing problem between the camera and the projector, a closed circle feedback strategy is proposed.

This paper presents a 3rd order continuous-time Delta-Sigma modulator with a tri-level quantizer, which provides 3-dB reduction of quantization noise without dynamic element matching (DEM). The tri-level DAC linearity is analyzed and it shows that a highly linear tri-level DAC can be realized in fully-differential active-RC Delta-Sigma modulator. The performance of the tri-level continuous-time Delta-Sigma modulator has been verified through simulations using a standard 0.18-μm CMOS process. It achieves 81-dB SNDR at 3.2-MS/s sampling rate and consumes 1.14-μW power with ideal amplifier.

The coercivity (Hc) and switching field (Hsw) of free layers increase remarkably with shrinking size, which reduces the sensitivity of spintronic devices. Conetic-alloy-based synthetic ferrimagnetic (SyF) trilayers are proposed to show reduced Hc and Hsw than single-layer in nanodots. The investigation on the thickness dependence reveals linear reliance of Hc and Hsw on amplification factor. Hc and Hsw are further reduced after field annealing at 200 °C. This work provides an approach to reduce the Hc and Hsw in nanomagnets.

X-ray absorption near edge structure (XANES) of O and Zn K-edge were shown, and a detailed analysis of extended x-ray absorption fine structure (EXAFS) of Zn K-edge indicates that difference substrates results in the contraction of Zn-O bond length.
