Continued growth in wireless, optical and other high-speed, high-frequency products has created a demand for integrated circuits that are opti-mized for performance, cost and practical development complexity. These radio-frequency ICs (RFICs) represent a wide range of requirements that continues to be met with an equally wide range of solu-tions, from low-cost ubiquitous CMOS to advanced III-V materials. In this tutorial, we’ll take a look at the major IC fabrication processes used for RFICs. Although there are variations among the var-ious facilities, there are general performance ranges that each process fits into. Hopefully, this note will provide an introductory-level understanding of the choices an engineer must make when choosing the right process to manufacture the device required for the end product being developed.
