Prime Faraday Technology Watch – January 2002 14
The three most well known market studies are the Network of Excellence in Multifunctional Microsystems (NEXUS) study (1998), the System Planning Corporation (SPC) study (1999) and the Battelle study (1990) and there is discrepancy between each study [23, 24, 25 respectively]. The size of the MEMS market (M 3 ) is contingent on how MEMS is defined (M 3 is shorthand for MEMS, Microsystems and Micromachining and although it is not yet common, it is used as a reference for the entire MEMS market. Smaller M 3 figures are obtained if MEMS is considered as just micromachining, which is more elemental and at the device level. Alternatively, much larger M 3 figures arise if MEMS is examined at the system or subsystem level (as in the case of NEXUS). Depending on the study under review, the M 3
market today ranges from $4.2 billion to $14.2 billion. Much of the current market centres on read/write heads for computer disk drives, pressure sensors, inkjet printer heads and accelerometers. Table 3 provides the NEXUS worldwide M 3 market size in 1996 and forecasts for 2002 for existing MEMS product types.
