The enhanced oxidation of Cu on Ru/diffusion barriers was observed. The in-situ X-ray diffraction results reveal that the Cu oxidation can be inhibited by doping C in either Ru adhesion layer or TaN barrier layer. The RuC/barrier becomes more robust with certain amount of C doped in Ru. ALD Cu 2 O on the RuC substrate was carried out and the effect of C on reduction of Cu oxide was observed.

This paper summarizes our recent investigations of nano-wire n type tunneling field effect transistor (n-TFET) reliability by experimental measurements and physical analysis [1-3]. Large PBTI and HC degradations which are very different from those in conventional n-MOSFETs were observed. The results are interpreted by different degradation mechanism in TFET.
We demonstrate electrically-pumped room-temperature continuous-wave lasing in InP-based micro-disc lasers with threshold current of 6.5mA. A non-concentric hole inside the disc is used to extract the light and control...

LDPC coding has attracted much attention due to its high performance, and it has been widely used in telecommunication systems. This paper focuses on the decoder hardware architecture, especially on memory size reduction, which is an important part of the entire area cost. The design has been post-layout simulated using a UMC 0.18 micron technology at a clock speed of 74 MHz. Using the proposed 3-level memory structure together with the described control logic, the required number of bits of memory can be reduced by up to 34.9% compared to prior approaches.

This paper presents a theoretical study on the possible realization of high frequency ultrasonic phased array transducer (f>100 MHz) using MEMS technologies. A silicon based lithium niobate (LiNbO3) single crystal linear array is considered. Finite element method is employed for the simulation optimization design of such device. Continuous wave beam steering, focusing under different array and matching conditions are simulated and the beam performance is analyzed. The inter-element crosstalking and the element electrical impedance are also calculated.
We propose and experimentally demonstrate a novel architecture for OFDM-PON system. The down link is based on single side band OFDM modulation while the up link makes use of the carrier information retained in another...
