Silicon carbide (SiC) is used in electric vehicles due to its wide bandgap and great thermal conductivity. Gallium nitride (GaN) shares many characteristics with SiC while also minimizing RF noise.
GPU vs CPU is a parallelization vs complexity dilemma. While GPUs can manage very large parallel calculations, they struggle with linear, more heterogeneous tasks, where CPUs excel.
The move to CFET vs GAAFET marks a switch from horizontally stacked transistors to vertically stacked ones. This will allow further shrinking of semiconductor patterns and the advancement of Moore´s Law.
Wire bonding is a cheap and reliable semiconductor packaging method- Flip-chip is an advancement, creating more dense interconnections and allowing 3D vertical stacking.
