Lapping carrier and method

A method of lapping comprising:

• a. providing a double-sided lapping machine having two opposed lapping surfaces or a single-sided lapping machine;
• b. providing a carrier comprising a base carrier having a first major surface, a second major surface and at least one aperture for holding a workpiece, said aperture extending from the first major surface through the base carrier to the second major surface, wherein
• i) the base carrier comprises a first metal,
• ii) the circumference of said aperture is defined by a third surface of the base carrier consisting of the first metal and,
• iii) at least a portion of the first major surface or at least a portion of each of the first and the second major surfaces comprises a polymeric region, said polymeric region comprising a polymer having a work to failure of at least 10 Joules;
• c. providing a workpiece;
• d. inserting the workpiece into the aperture;
• e. inserting the carrier into the lapping machine;
• f. providing relative motion between the workpiece and the lapping surface while maintaining contact between the lapping surface and the workpiece;
• and
• g. removing at least a portion of the workpiece.
