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.

摘要: Methods of producing integrated circuits are provided. An exemplary method includes patterning a source line photoresist mask to overlie a source line area of a substrate while exposing a drain line area. The source line area is between a first and second memory cell and the drain line area is between the second and a third memory cell. A source line is formed in the source line area. A source line dielectric is concurrently formed overlying the source line while a drain line dielectric is formed overlying a drain line area. A drain line photoresist mask is patterned to overlie the source line in an active section while exposing the source line in a strap section, and while exposing the drain line area. The drain line dielectric is removed from over the drain line area while a thickness of the source line dielectric in the strap section is reduced.

摘要: Embodiments of a method for forming a device using test structures are presented. The method includes providing a wafer with a device layer. The device layer includes a main device region and a perimeter region. The device layer is patterned with active and test patterns. Test patterns include dummy patterns disposed in a test device area. The wafer is processed to form at least one test device disposed in the perimeter region and one or more active devices disposed in the main device region. The test device determines a design window of the one or more active devices. Additional processing is performed to complete forming the device.

摘要: Integrating magnetic random access memory with logic is disclosed. The magnetic tunnel junction stack of a magnetic memory cell is disposed within a dielectric layer which serves as a via level of an interlevel dielectric layer with a metal level above the via level. An integration scheme for forming dual damascene structures for interconnects can be formed to logic and memory cells easily.

摘要: A semiconductor device with a temporary discharge path. During back-end-of-line (BEOL), the temporary discharge path discharges a plasma charge collected in a device well, such as a floating p-type well. After processing, the temporary discharge path is rendered non-function, enabling the device to function properly.
