Semiconductor Engineering was created by chip architects, engineers, journalists, end users, industry organizations and standards bodies to provide deep insights into the increasingly complex task of designing, testing, verifying, integrating and manufacturing semiconductors, as well as insights into the market dynamics that make it all possible. The goal of this site is to provide useful, independently developed content through targeted monthly newsletters, weekly updates, timely news alerts, videos, independent research, and a portal that serves as a forum for exchanging ideas and answering questions. While this site is supported by sponsors, all content developed by our writers adheres to the highest journalistic standards for editorial integrity and unbiased reporting. All stories are professionally written and edited by independent journalists and engineers with deep industry knowledge and experience, and all vendor involvement is limited to providing expertise rather than promoting their products. Sperling Media Group LLC was formed in 2008 to provide a free flow of unbiased information about technology and business issues in narrow but technologically challenging markets. At a time when complexity is at its peak and real insight is essential, the number of independent sources for that information is shrinking.
