B 81MICRO-STRUCTURAL TECHNOLOGY [7]


B 81 BMICRO-STRUCTURAL DEVICES OR SYSTEMS, e.g. MICRO-MECHANICAL DEVICES (piezo-electric, electrostrictive or magnetostrictive elements per se H01L 41/00) [7]


Notes

(1)This subclass does not cover: [7]

 purely electrical or electronic devices per se which are covered by section H, e.g. subclass H01L; [7]

 purely optical devices per se which are covered by subclasses G02B or G02F; [7]

 essentially two-dimensional structures, e.g. layered products which are covered by subclass B32B; [7]

 chemical or biological structures per se which are covered by section C; [7]

 structures in atomic scale produced by manipulation of single atoms or molecules, which are covered by group B82B 1/00. [7]

(2)Devices or systems classified in this subclass are also classified in appropriate subclasses providing for their structural or functional features, if such features are of interest. [7]

(3)Attention is drawn to the following places: [7]

 A61K 9/50  Microcapsules for medicinal preparations [7] 

 B25J 7/00  Micromanipulators [7] 

 G02B 21/32  Micromanipulators combined with microscopes [7] 

 G11B 5/127  Magnetic heads [7] 

 H01P 3/08  Waveguide microstrips [7]
