In this study, a cylindrical glass tube for near-field electrospinning (NFES) with multi-spinnerets is modified to fabricate polyvinylidene fluoride (PVDF) nanofibers on polyethylene terephthalate (PET) in large area. For the process, the traditional NFES is replaced by micro-drills technology which is used to design multi-spinnerets and drill spinnerets on the solder balls. PVDF solutions were formulated...
Based on the new finding on switching behavior, for the first time a new memory operation principle is proposed to control the switching and to achieve improved performance of oxide-based RRAM including device-to-device and cycle-to-cycle uniformity, RESET current, and window of RHRS/RLRS ratio. Furthermore, a numerical simulation method is developed to evaluate the validity of the new operation principle...
Effect of backend interconnect critical dimension variation on IMD TDDB is studied. Statistical data shows that low-k dielectric TDDB time to failure correlates well with leakage current, which reflects actual trench-to-trench or trench-to-via spacing. So a lifetime projection method, based on equal electric field, is reported. A more realistic lifetime is achieved while predicting whole lot TDDB...
During the growth of water trees in the XLPE cable insulation, the distribution of the electric field is modified because of the local change of the dielectric properties of the material. A better knowledge of the comparative danger for the different kinds of water trees could lead to a way of improving the quality of cable insulation. Numerical analysis results show that the dielectric permittivity...
