    Abstract: In a method of manufacturing an MRAM device, a first sacrificial layer, an etch stop layer, and a second sacrificial layer are sequentially formed on a substrate and then partially etched to form openings therethrough. Lower electrodes are formed to fill the openings. The first and second sacrificial layers and portions of the etch stop layer are removed to form etch stop layer patterns surrounding upper portions of sidewalls of the lower electrodes, respectively. An upper insulating layer pattern is formed between the etch stop layer patterns to partially define an air pad between the lower electrodes. A first magnetic layer, a tunnel barrier layer, a second magnetic layer, and an upper electrode layer are formed, and are etched to form a plurality of magnetic tunnel junction (MTJ) structures. Each MTJ structure includes a sequentially stacked first magnetic layer pattern, tunnel layer pattern, and second magnetic layer pattern, and each of the MTJ structures contacts a corresponding one of the lower electrodes.

    Abstract: A semiconductor device is formed with a normal, non-recessed, spacer structure in a cell region and a recessed spacer structure in a peripheral region. The recessed spacer structure is formed as by etch masking those in the cell region and exposing those in the peripheral region, then performing an etch process. The increased height of the cell region spacers is adapted to further prevent over-etching during gate interconnect formation which would otherwise result in etching through the spacer to the substrate and subsequent short circuit. Therefore, it is also possible to prevent bridge defects due to over-etching, which occurs because the barrier metal layer for a subsequent interconnection contact is accidentally connected to the underlying substrate. Also, since the recessed spacer structure is provided in the peripheral region, it is possible to remarkably enhance a resistance distribution of a cobalt silicide layer occurring in a gate line width of 100 nm or less.

    Abstract: An image pickup device and a manufacturing method thereof. A digital signal processing (DSP) chip is attached on a first surface of a substrate. A CMOS image sensor (CIS) chip is attached on an active surface of the DSP chip. The DSP chip and the CIS chip may be electrically connected to the substrate by wire bonding. A housing kit having a lens configured to transmit an image to the DSP chip may be mounted on the substrate. An inner space between the housing kit and the substrate is not molded, thereby simplifying a manufacturing process and providing a thinner and/or lighter image pickup device.

    Abstract: A method for fabricating a MOS transistor using a self-aligned silicide technique is provided. The method includes forming a gate electrode and a silicidation resistant layer pattern that are sequentially stacked on a predetermined region of a semiconductor substrate. Impurities are implanted into the semiconductor substrate to form a source/drain region. A first metal silicide layer is selectively formed on the surface of the source/drain region. The silicidation resistant layer pattern is then removed to expose the gate electrode. A second metal silicide layer is selectively formed on the exposed gate electrode. Consequently, the first metal silicide layer can be formed of a metal silicide layer having superior tolerance with respect to junction spiking. Also, the second metal silicide layer can be formed of another metal silicide layer having a low variation of resistivity due to the variation of the line width of the gate electrode. Therefore, it is possible to fabricate a high-performance MOS transistor suitable for a highly integrated semiconductor device.
