Micro machining machining of micro parts is not literally correct.

Micro machining and fabrication wikipedia. The fabrication of these devices is usually done by two techniques surface micromachining and bulk micromachiningto do bulk micromachining the region needed is highly doped with boron and the unwanted silicon is etched in liquid silicon etches. Whereas surface micromachining creates structures on top of a substrate bulk micromachining produces. Material removal at micronano level with no constraint on the size of the component. Assisted hybrid micro machining processes. Replication and parallel fabrication of hundreds or millions of identical. For assisted hybrid micro machining the major machining process is superimposed with input from one or several types of energy such as ultrasonic vibration laser fluid magnetic field etc. Unlike surface micromachining which uses a succession of thin film deposition and selective etching bulk micromachining defines structures by selectively etching inside a substrate. Surface micro machining involves as many layers as are needed with a different mask producing a different pattern on each layer. Laser micro machining technique finds application in the manufacture of micro channels and micro holes in integrated chips and microchips. Isbn 978 953 307 906 6 pdf isbn 978 953 51 6095 3 published 2012 02 03. So as to improve the constituent micro machining process. If an internal link led you here you may wish to change the link to point directly to the intended article. The technique for fabrication of 3d and 2d structures on the micrometer scale. Creating micro features or surface characteristics especially surface finish in the micronano level. Surface micro machining is characterized by the fabrication of micro mechanical structures from thin deposited thin films.

Micro holes on integrated chips micro channels on integrated chips continued. Traditional machining techniques such as electro discharge machining spark erosion machining and laser drilling have been scaled from the millimeter size range to micrometer range but they do not share the main idea of microelectronics originated microfabrication. This disambiguation page lists articles associated with the title micromachining. Mechanical type advanced micro machining processes 2 abrasive jet micro machining ajmm 3 ultrasonic micro machining usmm 4 abrasive water jet micro machining awjmm part 2. Micro machining is a younger technology and usually uses no more than 5 or 6 layers. Modern integrated circuit fabrication uses this technique and can use as many as 100 layers. Micromachining techniques for fabrication of micro and nano structures. Removal of material in the form of chips or debris having the size in the range of microns.
