The invention provides methods and systems for the application and reading of micro markings for coding of information for placement on the surfaces of individual very small devices. In preferred embodiments, a two dimensional micro matrix of markings or dots is realized on a scale of a 25 um cell size and smaller.
Claims48
A method for marking an object with a micro marking, comprising the steps of:
- forming a micro matrix pattern on a surface of the object by changing at least one physical property of a portion of the surface of the object;
- and subsequently,
- reading the micro matrix pattern using a reader adapted for discerning the micro matrix pattern.
A micro matrix data marking and reading system comprising:
- a marking apparatus for forming micro matrix cells on the surface of an object by physically changing portions of the object surface;
- a reader for reading encoded micro matrix data cells formed by the marking apparatus;
- and
- a handler for manipulating the object for marking and reading.
