Abstract
<PICT:0942135/C3/1> <PICT:0942135/C3/2> A method of treating, e.g. etching or plating, the surface 32 of a semi-conductor 23 comprises directing a jet 27 of a liquid against a portion 31 of the surface so as to form a sheet of liquid 33 flowing outwardly away from the portion 31 and breaking up into drops 36 in a region 35 remote from the portion 31, and directing a current of gas, e.g. air, across the sheet 33 with such a velocity as to carry the drops 36 away from the region 35 without reversing the flow of liquid in the sheet 33. The semi-conductor 23 is mounted in a closed-ended housing 10 the other end of which is connected to an air pump which discharges into a reservoir from which liquid is pumped to a nozzle 20. The housing 10 may be transparent and be illuminated from directions 25, 26. An air current 37 is drawn in at 29 and traverses the sheet 33 diametrically, removing the drops 36 mainly from an arc of the periphery 34 of the sheet 33 located downstream of the portion 31, the speeds of the pumps being suitably adjusted. In the modification, Fig. 5 (not shown), the workpiece 23 is introduced longitudinally into the end of the housing 10, which is open at both ends, and opposed jets of liquid are delivered radially into the housing. In another modification, Fig. 6, the workpiece 23 is supported transversely of the housing 70 and a jet 75 is delivered normal to the workpiece 23 and axially of the housing 70 which is again open at both ends, the air stream 81 carrying the drops 78 from the periphery 80 of the sheet 79. An electrode may contact the liquid where electrolytic etching or plating is required.
