eSilicon was founded in 1999 in San Jose, California, by Anjan AJ Sen.[3][4] He conceived the concept while attending Harvard Business School in 1997 based on his prior experience as a chip designer.
Sen wrote the business plan, assembled the initial team, incorporated the company in November 1999, and secured key alliances with TSMC and Artisan, which led to Series A financing in March 2000.
[10] In January 2008 eSilicon acquired the assets of Swedish-based Ethernet networking switch supplier SwitchCore AB and announced that they would seek further acquisitions.
[12][13][14] In 2011, eSilicon started the MoZAIC™ “Modular Z-axis Integrated Circuit” 2.5D ASIC program[15] to analyze new approaches that would provide more bandwidth for customers.
[17][18] Customer ASICs have been announced in a wide range of applications including high-bandwidth networking, high-performance computing, digital cameras, hearing aids, portable multimedia players and inkjet printers.
