Abstract

A method of forming a ramp of material on a stepped portion of an item, comprises applying material in liquid form to the item in the vicinity of the stepped portion, the liquid having properties such that the liquid moves by capillary attraction to the stepped portion, and causing or allowing the material to solidify to form a ramp on the stepped portion. By using capillary flow, it is not necessary for the material to be placed in position very accurately. Variations in position of placement can be accommodated by the flow to the stepped region. The greater tolerance in accuracy of positioning means that processing can be performed more quickly.
