From its beginning in 1978 as the GaAs IC symposium, the IEEE Compound Semiconductor IC Symposium (CSICS) has evolved to become the preeminent international forum for developments in compound semiconductor integrated circuits and devices, embracing GaAs, InP, GaN, SiGe, and CMOS technology. Coverage includes all aspects of the technology, from materials, device fabrication, IC design, testing, and system applications. CSICS provides the ideal forum to present the latest results in high-speed digital, analog, microwave, millimeter wave, THz, mixed-mode, and optoelectronic integrated circuits. First-time papers addressing the utilization and application of InP, GaAs, GaN, Silicon, Germanium, SiGe, and other compound.
