Microtechnology is the fabrication of millimetre sized devices with micron and nano-sized rules by bulk deposition and patterning millions of atoms in any part.
Micro-Nano-Technologyis the use of the properties of micro and or nano-technology in micro and macro applications for further shrinking, integration and miniaturisation of sensing & actuating functions and for microsystems.
Nano-Technology (Molecular T)is the building up of structures or materials in an atom-for-atom specific way; every atom counts Theoretically anything could be built

Advanced fabrication techniques• Development of etching and bonding techniques• Introduction of new equipment
Facilitating the next steps in MEMS technologyto provide improved design flexibility for future devices
These proposed structures will lead to new or improved devices, eg miniature pneumaticsthrusters, fuzing elements, actuators, motors etcPresent 2 1/2 D deep etch is
limited to ‘extrusion’ in 3rd dimension
