Marveling at MEMS: The New Superheroes of The Silicon World

Moore's Lobby: Where engineers talk all about circuits

Silicon transistors naturally get most of the attention. However, delicate silicon microelectromechanical systems (MEMS) with movements that are often measured in angstroms are making some noise of their own (metaphorically, because you won’t be able to hear those tiny vibrations!).

By focusing in parallel on the MEMS device and the silicon processing required to build them, SiTime has been able to improve MEMS resonator performance “close to 100,000” times, says Fari Assaderaghi, EVP of Technology and Engineering at SiTime.

Assaderaghi went on to state:

“Timing is like an unsung hero that is behind the scenes, but its performance actually limits or enables certain performance characteristics that you see at the end systems.”

Over his career, Fari learned many important lessons that he shares during this thoughtful interview. One of these is to “always go back to first principles.” He expounds on this by stating, “If you don't understand something, don't paper over it. Keep on digging.” He concludes with the warning, “There is no shortcut, and if the fundamental doesn't support it, eventually it's going to come and get you.”

Assaderaghi also learned to focus on your ultimate goal rather than what you think is possible. “If you start with what you want to achieve...you would be surprised that eventually what you thought was not possible, actually it is possible.”

Our Moore’s Lobby host, Daniel Bogndanoff, also discusses with Assaderaghi his fascinating personal journey. Over his career, Assaderaghi has had the pleasure of working alongside luminaries like Chenming Hu, the father of Finfets; Robert Dennard, the inventor of single-transistor DRAM; and Lisa Su, CEO of AMD.

Other highlights from this interview include:

-The unique SiTime culture that Fari credits to the CEO, Rajesh Vashist. -The importance of failure -The tuning of silicon’s mechanical properties, not just electrical

That’s a wrap on Season 6 of Moore’s Lobby. We hope you have enjoyed hearing from these amazing guests as much as we have. Please tell us what you think in the comments or share your suggestions and requests for guests and topics for Season 7.
