Abstract:
Disclosed herein is a workpiece processing method including a mask preparing step of preparing a mask that covers devices on a front surface of a workpiece and exposes streets, a plasma etching step of repeating an operation of supplying plasmatized SF 6  through the mask to the workpiece accompanied by a holding member disposed on a back surface thereof, to form grooves, then supplying plasmatized C 4 F 8  to the workpiece through the mask to deposit a coating on the workpiece, and thereafter supplying plasmatized SF 6  to the workpiece through the mask to remove the coating present at bottoms of the grooves, thereby etching the groove bottoms, and a foreign matter removing step of cleaning the workpiece with a cleaning liquid, after the plasma etching step is conducted, to remove the coating produced in the plasma etching step.

Claim (Index 1):
A processing method for a workpiece which has a front surface formed with a device in each of regions partitioned by a plurality of intersecting streets, the device being provided with projecting electrodes, the processing method comprising:\n a mask preparing step of preparing a mask that covers the devices on the front surface of the workpiece and exposes the streets; a plasma etching step of repeating an operation of supplying plasmatized SF 6  through the mask to the workpiece in which the devices on the front surface are covered with the mask and which is accompanied by a holding member disposed on a back surface thereof, to form grooves, then supplying plasmatized C 4 F 8  to the workpiece through the mask to deposit a coating on the workpiece, and thereafter supplying plasmatized SF 6  to the workpiece through the mask to remove the coating present at bottoms of the grooves, thereby etching the groove bottoms; and a foreign matter removing step of cleaning the workpiece with a cleaning liquid, after the plasma etching step is conducted, to remove the coating produced in the plasma etching step.
