4. Applications of Si1-xGex alloys for Ge devices and monolithic 3D integration
Abstract : As the semiconductor industry moves beyond the 10 nm node, power consumption constraints and reduction of the negative impact of parasitic elements become important. Silicon germanium (Si1−xGex) alloys have been used to amplify the performance of Si based devices and integrated circuits (ICs) for decades. READ MORE
