This disclosure describes a microelectromechanical device comprising at least one mobile rotor. The rotor comprises a rotor measurement region and a rotor stopper region and a rotor isolation region which connects the rotor measurement region mechanically to the rotor stopper region and isolates the rotor measurement region electrically from the rotor stopper region.

Microelectromechanical device with stopper

A microelectromechanical device comprising a mobile rotor in a silicon wafer. The rotor comprises one or more high-density regions. The one or more high-density regions in the rotor comprise at least one high-density material which has a higher density than silicon. The one or more high-density regions have been formed in the silicon wafer by filling one or more fill trenches in the rotor with the at least one high-density material. The one or more fill trenches have a depth/width aspect ratio of at least 10, and the one or more fill trenches have been filled by depositing the high-density material into the fill trenches in an atomic layer deposition (ALD) process.

MEMS element with increased density

An atomic deposition (ALD) thin film deposition apparatus includes a deposition chamber configured to deposit a thin film on a wafer mounted within a space defined therein. The deposition chamber comprises a gas inlet that is in communication with the space. A gas system is configured to deliver gas to the gas inlet of the deposition chamber. At least a portion of the gas system is positioned above the deposition chamber. The gas system includes a mixer configured to mix a plurality of gas streams. A transfer member is in fluid communication with the mixer and the gas inlet. The transfer member comprising a pair of horizontally divergent walls configured to spread the gas in a horizontal direction before entering the gas inlet.
