micromachining
Noun
Meaning
micromachining (plural micromachinings)
microfabrication
Examples
Analog Devices has pioneered the industrialization of surface micromachining and has realized the co-integration of MEMS and integrated circuits.
Bulk micromachining has been essential in enabling high performance pressure sensors and accelerometers that changed the sensor industry in the 1980s and 90's.
Integrated circuits are typically not combined with HAR silicon micromachining.
MEMS manufacturing technologies Bulk micromachining main Bulk micromachining is the oldest paradigm of silicon based MEMS.
The materials commonly used in HAR silicon micromachining are thick polycrystalline silicon, known as epi-poly, and bonded silicon-on-insulator (SOI) wafers although processes for bulk silicon wafer also have been created (SCREAM).
While it is common in surface micromachining to have structural layer thickness in the range of 2 µm, in HAR silicon micromachining the thickness can be from 10 to 100 µm.
