Title: Method for measuring life of electromigration of wiring layer and instrument therefor
Inventor: HIRAOKA KAZUNORI
IPC: G01R31/26
Filed: 1989-08-18
Abstract: PURPOSE:To allow error-free measurement by supplying a DC current in one direction to one of the same two wiring layers and the DC current alternately iterating in forward and backward directions in the other thereof respectively until the wiring layers are disconnected and determining TE=T1.T2/(T2-T1) from both time T1, T2 thereof. CONSTITUTION:The same two wiring layers 11, 12 to be measured are prepd. The resistance value between connecting terminals P1 and P2 changed at the point t0 of energization start time and the point ts of disconnection start time when the wiring layer 11 is first connected between the terminals P1 and P2 and when the DC current is supplied in one direction from the power source 2 until the wiring layer is discon nected. The measurement output S1 indicating this change is, therefore, obtd. by the measuring instrument 3 and the time T1 between the points t0 and ts of time is obtd. by a time measuring instrument 4. The wiring 12 is then changed to 11 and the DC current alternately iterating in forward and backward directions is supplied thereto until the wiring is disconnected. The time T2 is similarly obtd. The TE=T1.T2/(T2-T1) is determined therefrom and the measurement output E is obtd. The measurement which does not include the errors by the thermal migration effect is executed in this way.

Filed: 1992-08-11
Abstract: PURPOSE:To obtain a high change rate of magnetoresistance by using an Ni-Fe based alloy having a face-centered cubic lattice structure as the magnetic layer to orient the (100) face of a magnetic layer crystal in parallel with the substrate. CONSTITUTION:In a magnetoresistance effect element using a multilayer that is a laminate of nonmagnetic layers 12, an Ni-Fe based allay having a face- centered cubic lattice structure is used as a magnetic layer 11 to orient the crystal (100) face of the magnetic layer 11 in parallel with the substrate. The relation between X-ray diffraction strength I200 by the crystal (200) face of the magnetic layer 11 and X-ray diffraction strength I111 by the crystal (111) face is designed so as to be I200/(I111+I200)>=0.4. The film thickness per layer of Ni-Fe based alloy should be 2.5-5mm. This process can provide a low saturation magnetic field and a high magnetoresistance effect simultaneously, which are suitable for magnetoresistance effect element, magnetic field sensor, magnetic head, etc., and this magnetic head is used to provide a high performance magnetic recording reproducer.
