摘要: Apparatus, and their methods of manufacture, including an integrated circuit device having metallization layers for interconnecting underlying electronic devices. Contacts contact conductors of an uppermost one of the metallization layers. A planarized first dielectric layer covers the contacts and the uppermost one of the metallization layers. An anisotropic magnetoresistive (AMR) stack is on the first dielectric layer between vertically aligned portions of an etch stop layer formed on the first dielectric layer and a second dielectric layer formed on the etch stop layer. Vias extend through the first dielectric layer to electrically connect the AMR stack and the contacts. A chemical-mechanical planarization (CMP) stop layer is on the AMR stack. A third dielectric layer is on the CMP stop layer. A passivation layer contacts the second dielectric layer portions, the third dielectric layer, and each opposing end of the AMR stack and the CMP stop layer.

摘要: A semiconductor package includes a semiconductor chip having Hall elements built therein, and external terminals arranged on one surface side of the semiconductor chip. A first Hall element and a second Hall element are arranged to be point-symmetrical with respect to a center point of the semiconductor package in a plan view. The first Hall element is at least partially covered by a first external terminal among first external terminals in a plan view, and the second Hall element is at least partially covered by a second external terminal among second external terminals in a plan view. A first region covered by the first external terminal of the first Hall element in a plan view and a second region covered by the second external terminal of the second Hall element in a plan view are point-symmetrical with respect to the center point of the semiconductor package in a plan view.

摘要: The output voltage of an MRAM is increased by means of an Fe(001)/MgO(001)/Fe(001) MTJ device, which is formed by microfabrication of a sample prepared as follows: A single-crystalline MgO (001) substrate is prepared. An epitaxial Fe(001) lower electrode (a first electrode) is grown on a MgO(001) seed layer at room temperature, followed by annealing under ultrahigh vacuum. A MgO(001) barrier layer is epitaxially formed on the Fe(001) lower electrode (the first electrode) at room temperature, using a MgO electron-beam evaporation. A Fe(001) upper electrode (a second electrode) is then formed on the MgO(001) barrier layer at room temperature. This is successively followed by the deposition of a Co layer on the Fe(001) upper electrode (the second electrode). The Co layer is provided so as to increase the coercive force of the upper electrode in order to realize an antiparallel magnetization alignment.

摘要: A method of manufacturing and resultant device are directed to an inverted wide-base double magnetic tunnel junction device having both high-efficiency and high-retention arrays. The method includes a method of manufacturing, on a common stack, a high-efficiency array and a high-retention array for an inverted wide-base double magnetic tunnel junction device. The method comprises, for the high-efficiency array and the high-retention array, forming a first magnetic tunnel junction stack (MTJ2), forming a spin conducting layer on the MTJ2, and forming a second magnetic tunnel junction stack (MTJ1) on the spin conducting layer. The first magnetic tunnel junction stack for the high-retention array has a high-retention critical dimension (CD) (HRCD) that is larger than a high-efficiency CD (HECD) of the first magnetic tunnel junction stack for the high-efficiency array. The second magnetic tunnel junction stack (MTJ1) is shorted for the high-retention array and is not shorted for the high-efficiency array.
