    摘要: Device and methods of forming a device are disclosed. The method includes providing a substrate defined with at least first and second regions. A first dielectric layer is provided over the first and second regions of the substrate. The first dielectric layer corresponds to pre-metal dielectric (PMD) or CA level which comprises a plurality of contact plugs in the first and second regions. A first interlevel dielectric (ILD) layer is provided over the first dielectric layer. The first ILD layer accommodates a plurality of metal lines in M1 metal level in the first and second regions and via contact in V0 via level in the first region. A magnetic random access memory (MRAM) cell is formed in the second region. The MRAM cell includes a magnetic tunnel junction (MTJ) element sandwiched between the M1 metal level and CA level.

    摘要: Devices and methods for forming a device are disclosed. The method includes providing a substrate having first and second surfaces. At least one through silicon via (TSV) opening is formed in the substrate. The TSV opening extends through the first and second surfaces of the substrate. An alignment trench corresponding to an alignment mark is formed in the substrate. The alignment trench extends from the first surface of the substrate to a depth shallower than a depth of the TSV opening. A dielectric liner layer is provided over the substrate. The dielectric liner layer at least lines sidewalls of the TSV opening. A conductive layer is provided over the substrate. The conductive layer fills at least the TSV opening to form TSV contact. A redistribution layer (RDL) is formed over the substrate. The RDL layer is patterned using a reticle to form at least one opening which corresponds to a TSV contact pad. The reticle is aligned using the alignment mark in the substrate.
