SiGe HBT is a key device for BiCMOS process used for high-speed communication, automotive radar and defense military. For normal SiGe process, the control of emitter window undercut is often not easy. In this paper, we studied the influence of emitter undercut on HBT parameters, through both TCAD simulation and wafer results. While transistors with larger area-to-perimeter ratio are supposed to have...
This paper reports on the first-ever integrated silicon microprobes for measuring strain and bio-electrical potentials wirelessly from the same location in biological tissue concurrently. Combining both modalities allows the study of coupled mechanical and electrical problems by simultaneous measurement. This can be useful for studying electrical and mechanical wave propagation in cardiac arrhythmias,...
Service selection is a kind of planning approach that evaluates and selects from multiple services to form a composite plan. In service selection, we found one additional issue that has not been investigated yet namely time constraints consistency among composite services. This issue is significant because there are potential time constraints involved that might cause inconsistency between selected...
In this paper, the authors present the performance characteristics of such a silicon nanocrystal split gate bitcell and report an optimal bitcell process and integration scheme for memory arrays.
