Title: Magneto-resistance effect type thin film head
Inventor: NAMIKATA RYOJI
IPC: G11B5/39
Filed: 1986-10-09
Abstract: PURPOSE:To suppress generation of Barkhausen noise by forming the magneto- resistance effect element itself to a folded shape and juxtaposing plural groove- shaped recesses to said magneto-resistance effect element in the direction of the axis of easy magnetization. CONSTITUTION:An upper yoke 6 is provided oppositely to the other end part side of an upper yoke via a gap 5 of a prescribed width. A base material 8 having the groove of a rectangular section in the longitudinal direction is pro vided on the lower side of the gap 5 and the magneto-resistance effect element (MR element) 7 which makes magnetical coupling to the upper yokes 4.6 is formed on the surface thereof. The MR element 7, therefore, has the longitudinal direction of the gap 5 in the longitudinal direction thereof and since the MR element 7 itself is formed by folding the element, the element has eventually the plural groove-shaped recesses 7a in the direction of the axis of easy magneti zation. The magnetic anisotropy in the direction of the axis of easy magnetiza tion is thereby provided on the MR element, by which the single magnetic domain is formed and the Barkhausen noise is suppressed.

Abstract: PURPOSE:To eliminate fluctuation in operation characteristics by forming a tunnel oxide film so as to obtain a tunnel current density that is sufficient for writing and erasing in the tunnel oxide film when a voltage which is smaller than a threshold voltage for generating electron-hole pairs is applied to the tunnel oxide film. CONSTITUTION:In an FLOTOX type nonvolatile memory, N<+> diffused layers 3 and 3' are formed in a P-type Si substrate 1. A tunnel oxide film having a thin oxide film, a floating gate 5, an insulating layer 6 and a control gate 7 are sequentially formed on said layer 3. Here, electron-hole pairs are generated when a voltage that is applied to the tunnel oxide film exceeds a certain threshold voltage value. When a voltage which is smaller than the threshold voltage value for generating the electron-hole pairs is applied at the time of electron injection, an electric field having the sufficient tunnel current density for writing and erasing is formed. The tunnel oxide film is formed with a thin oxide film so that said electric field is applied to the tunnel oxide film. In this way, the sufficient tunnel current density can be obtained without fluctuating the threshold voltage for writing and erasing.
