摘要： In a thin film magnetic head of the present invention, lead formation patterns of a first lead for connection between a lower shield layer and a first extraction electrode portion and a second lead for connection between an upper shield layer and a second extraction electrode portion are each formed so as not to have an overlapping portion with a heatsink layer but to bypass the heatsink layer when observing from the upper shield layer side toward the lower shield layer in a transparent state in plan view. Therefore, it is possible to increase an effect of heat radiation to the substrate side on the basis of the presence of the heatsink layer to thereby limit propagation of heat to a magnetoresistive effect layer as much as possible and further to achieve a drastic improvement in recording and reproducing characteristics at high recording frequencies, i.e. frequency characteristics (f characteristics) in a high frequency region.

摘要： A lapping monitor element that is juxtaposed with a magnetic transducer element having a magnetoresistance effect film to determine the lapping position upon lapping the element height of the magnetic transducer element to a predetermined dimension. The lapping monitor element includes a resistance film to be resistance measured. The resistance film is a metal film of nonmagnetic transition metal or of alloy composed mainly of nonmagnetic transition metal, or a multilayered film where two or more such metal films are laid one upon another. The lapping monitor makes it possible to extremely stabilize the ELG sensor resistance measured values upon lapping as well as to provide a high accuracy MR height control.

摘要： The present invention relates to a wafer formed with an evaluation element and capable of improving productivity and a manufacturing method of an electronic component using the same. In a wafer according to the present invention, a plurality of elements connected to electrode films through lead-out conductive films are arranged and a chip area is defined for cutting out the plurality of elements in a given number. In the wafer, at least one evaluation element is formed in an area outside the chip area. The lead-out conductive films extend to the outside area and are connected to the evaluation elements. With this wafer, since the lead-out conductor is shared between the element and the evaluation element, the electrode film connected therewith can be shared, too. Accordingly, evaluation can be performed by using the evaluation element without the need of providing the wafer with a lead-out conductor and an electrode film exclusively for the evaluation element, so that the chip area to be cut out from the wafer can be made larger than before.
