Abstract: The present disclosure includes methods of lapping that include energizing one or more elements that are located proximal to a first magnetoresistive element in a transducer region and generate heat and cause the first magnetoresistive element to selectively expand in the lapping direction relative to one or more other magnetoresistive elements. The present disclosure also includes methods of lapping that use one or more thermal sensors located proximal to the first magnetoresistive element to help control lapping in the lapping direction. The present disclosure includes related lapping systems and sliders.

Abstract: Described are methods for processing microelectronic device substrates by a lapping step, e.g., a final lapping step, wherein the step includes the use of an elastomeric pressure-sensitive adhesive to secure the microelectronic device substrate to a carrier that holds the substrate to a surface of the carrier during the lapping step, and wherein the pressure-sensitive adhesive can be a non-polysilicone based adhesive having mechanical properties that include a tan delta that is below about 0.2.

Abstract: The present disclosure involves apparatuses and methods for coating a lapping plate with an aqueous composition. The apparatus can be configured and the aqueous composition can be formulated so that the aqueous composition can flow to a spray nozzle device solely due to gravity in a batchwise manner.

Abstract: The present disclosure includes a lapping system that includes a temperature control system system to heat or cool the lapping plate while lapping. The temperature control system can include a closed circuit fluid system and/or one or more electrical resistive heating elements. In some embodiments that cooling system can control the temperature of the lapping plate during lapping to within +/−5° C., or even +/−0.5° C.
