Abstract
The present invention provides for depositing a desired pattern (31) of magnetic material (30) on a non-magnetic substrate (20). Control of the deposition pattern (31) is achieved by use of a magnetised template (10) shaped to correspond to the desired deposition pattern. In use, the template (10) is placed behind the substrate (20). Subsequently, the front surface of the substrate (20) is exposed to a solution containing the magnetic material (30) to be deposited. The magnetic material (30) is attracted to the magnetised template (10) and consequently is deposited in a pattern (31) covering areas corresponding to the shape of the template (10).
Claims18
A method of selectively depositing a desired pattern of a material on a front surface of a non-conductive substrate, the method comprising the steps of:
- providing a magnetised template corresponding to the pattern to be deposited;
- positioning the template behind the substrate;
- and exposing at least the front surface of the substrate to one or more solutions containing magnetic catalytic material to be deposited and selectively depositing a desired secondary material on the deposited catalyst pattern.
