    • 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.
    • 本发明涉及一种形成有评估元件并且能够提高生产率的晶片以及使用其的电子部件的制造方法。 在根据本发明的晶片中,布置了通过引出导电膜连接到电极膜的多个元件,并且限定了用于切割给定数量的多个元件的芯片面积。 在晶片中,在芯片区域外的区域中形成至少一个评估元件。 引出导电膜延伸到外部区域并连接到评估元件。 对于该晶片,由于引出导体在元件和评估元件之间共享,所以与其连接的电极膜也可以共享。 因此,可以通过使用评估元件进行评价,而不需要为评估元件专门提供引出导体和电极膜,从而可以使从晶片切出的芯片面积更大 比以前。

    • Provided is a thin-film magnetic head in which the magnetic spacing can be appropriately controlled by dynamically and accordingly, by adjusting the pressure working between the thin-film magnetic head and the magnetic recording medium according to the change of conditions such as the change over time. The thin-film magnetic head comprises at least one cavity for adjusting a pressure working between the thin-film magnetic head and the magnetic recording medium, provided in a surface of the head opposed to the magnetic recording medium, and a volume of the at least one cavity being variable. When the magnetic recording medium passes through near the cavity, the cavity generates a (negative) pressure that attracts the head and the medium toward each other. The amount of the negative pressure depends on the volume of the cavity; thus, a magnetic spacing dMS can be controlled dynamically and accordingly by adjusting the volume.
