LSI Computer Systems, Inc. (LSI/CSI)Founded in 1969 by Alvin Kaplan and Attila Tetik, LSI Computer Systems, Inc. began as the world’s first fabless semiconductor company. Today, the Melville, New York firm designs and produces integrated circuits for manufacturers whose products depend on precise electronic control, including full-custom chips developed for specific high-volume applications.MELVILLE, NY
Linear ASICsLinear ASICs helps embedded, IoT, and consumer-electronics companies turn discrete designs into application-specific integrated circuits, with a particular focus on analog and mixed-signal engineering. Based in Tallmadge, Ohio, the firm works with clients from system architecture and circuit optimization through ASIC development and high-volume production and test.TALLMADGE, OH
Slip Signal TechnologiesSlip Signal Technologies is a Baltimore semiconductor design company developing digital logic circuits that reduce electromagnetic interference at its source. The company grew from electrical engineers’ recurring lab problems with EMI and is led by co-founders and technology specialists with more than 50 years of combined experience in electronic design, interference, and regulatory compliance. Its next-generation circuits have progressed through simulation, functional testing, and a printed-circuit-board MVP.BOWIE, MD
Heisler Semiconductor LLCHeisler Semiconductor is an engineering-led company built around a Maryland lab and a domestic, NDA-first approach to difficult hardware programs. It helps fabless and other high-reliability teams move from design review to qualified volume, with the same engineers carrying ownership through development and validation on U.S. soil.HALETHORPE, MD
