Sand 9

Pritiraj Mohanty, a Boston University physicist, and Matt Crowley, former director of Boston University's technology development fund, co-founded Sand 9 in 2007.[1] The company aimed to produce timing products with a better price-to-performance ratio than quartz in core markets.[1]

Sand 9 introduced their first two products, TM061 and TM361, on September 3, 2013.[9] TM061 and TM361 are precision MEMS timing products for the Internet of Things and mobile devices.[9][10][11] On November 18, 2013, the TM651 was introduced for communications infrastructure, industrial and military applications.[9][10] According to EE Times, a trade publication, the TM651 is the first high-precision temperature compensated MEMS oscillator (TCMO) to meet the noise and stability demands of communication, industrial and military applications.[10][12] TM061 started sampling to lead customers in November and the TM361 in December 2013.[13]

GLOBALFOUNDRIES, a semiconductor foundry, is Sand 9's foundry partner.[4] GLOBALFOUNDRIES produces approximately one thousand 200 mm wafers per month.[4]

Sand 9 developed its piezoelectric MEMS resonator technology as an alternative to quartz timing devices.[16] Sand 9 uses aluminum nitride, a thin film that is deposited using standard semiconductor/MEMS fabrication technology, for the piezoelectric layer. The silicon MEMS products are smaller than comparable quartz devices and currently operate at fundamental frequencies up to 125 MHz.[4] Silicon-based MEMS products can simplify system design, reduce part counts, simplify the supply chain, and improve manufacturing yields when compared to quartz.[4] Sand 9 MEMS products can be co-packaged and overmolded with standard semiconductor ICs to eliminate the need for external timing.
