Joe Mackey

Vice President, Technology Development

Joe began his career in the semiconductor industry in 1983 on the equipment engineering side of wafer manufacturing. Over the course of the next 16 years, Joe worked in various engineering departments covering equipment and device positions supporting wafer manufacturing and process development for integrated device manufacturers such as Synertek, TRW, Raytheon, and Applied Micro Circuits.

In 1998, Joe joined Atmel’s NVM technology development group as senior manager of their Device & Modeling engineering team. One notable achievement at Atmel was Joe’s success in the development of a robust Production and TD engineering e-test program. Joe then joined Silicon Laboratories in 2006, a fabless company, where he supported all foundry business & technical activities for the MCU – embedded mixed signal division. While there, Joe lead efforts in the development of a low mask count memory (flash) process which significantly lowered manufacturing cost and cycle time.

Joe joined TSI Semiconductors in 2011 and proceeded to set up the foundry process support and design enablement teams. Since joining TSI, Joe has spearheaded the development of 0.25um BCD process PDK and is actively engaged as the technology leader in the development of a high performance new technology node (0.18um). Beyond those accomplishments, Joe has supported mass production products run on BCD, flash, logic & mixed signal/RF from 0.8um to 55nm. Today, he manages the key technical teams – Process Integration, CAD, Customer Support, Device Modeling, Layout, and PDK development.

Joe earned his Bachelor of Science degree in Electrical Engineering from the University of California, San Diego and his Masters of Science degree in Electrical Engineering from Colorado Technical University, in Colorado Springs.
