A beam scannable 4×4 patch array antenna using the tunable metamaterial (MTM) phase shifter has been designed at S-band. The phase shifter consists of four MTM unit cell composed of a series variable capacitor and a shunt tunable inductor. The inductor is realized by a variable capacitor and quarter wave impedance transformer. The phase shifting range of the phase shifter is 280° (from −87° to 193°)...
We compared WSix/WN and Ti/WN diffusion barriers for tungsten dual polymetal gate (W-DPG) application, in terms of device performance and gate oxide reliability. WSix/WN diffusion barrier shows degradation of gate oxide, which is found to be due to the B-N dielectric formation and subsequent breakdown of diffusion barrier. Relatively, Ti/WN diffusion barrier shows excellent device performance in terms...
