摘要:
A method for measuring an area resistance of a magneto-resistance effect element which includes an upper-barrier layer having a first sheet resistivity Rt, a barrier layer, and a lower-barrier layer having a second sheet resistivity Rb, includes a resistance measurement step, a sheet resistivity measurement step and a establishing step. The resistance measurement step is the step of measuring a resistance R of the magneto-resistance effect element by using predetermined terminals. The sheet resistivity measurement step measures the first sheet resistivity Rt and the second sheet resistivity Rb. The establishing step determines the area resistance RA of the magneto-resistance effect element using the first sheet resistivity Rt, the second sheet resistivity Rb, the resistance R and the intervals among the predetermined terminals.

A method of measuring resistance of a tunnel magnetoresistive element having a first conductive layer, a resistive layer and a second conductive layer stacked on a substrate in this order. This magnetoresistive element has a pinned layer on one of the first and second low resistance layers, and a free layer on the other, and a barrier layer sandwiched between the pinned and free layers serving as the resistive layer. The method includes preparing a sample including in the following stacking order on the substrate a first low resistance layer having a low resistance, a thin film constituting the tunnel magnetoresistive element and having a constitution identical to the thin films formed of the first conductive, resistive, and second conductive layers and a second low resistance layer having a low resistance, and applying a resistance measurement probe to a surface of the sample to measure resistance of the thin film.

In editing of a job parameter in a semiconductor exposure apparatus controlled by the job parameter, which is a collection of parameters, a first parameter set independent of the model of the semiconductor exposure apparatus and a second parameter set dependent upon the model are edited and saved independently. This makes it possible to improve operability of parameter editing and management in the semiconductor exposure apparatus, ease of maintenance thereof and the ability to use job parameters among various models of apparatus.
