Structure and fabrication of an MRAM cell

MTJ stacks formed using prior art processes often fail because of shorts between the pinned layer and the top electrode. This problem has been overcome by depositing a protective layer on the MTJ sidewalls followed by an inter-layer dielectric. Then planarizing until the protective layer is just exposed. Finally, an etching (or second CMP) process is used to selectively remove the protective layer from the top surface of the cap layer.

Process options of forming silicided metal gates for advanced CMOS devices

Silicide is introduced into the gate region of a CMOS device through different process options for both conventional and replacement gate types processes. Placement of silicide in the gate itself, introduction of the silicide directly in contact with the gate dielectric, introduction of the silicide as a fill on top of a metal gate all ready in place, and introduction the silicide as a capping layer on polysilicon or on the existing metal gate, are presented. Silicide is used as an option to connect between PFET and NFET devices of a CMOS structure. The processes protect the metal gate while allowing for the source and drain silicide to be of a different silicide than the gate silicide. A semiconducting substrate is provided having a gate with a source and a drain region. A gate dielectric layer is deposited on the substrate, along with a metal gate layer. The metal gate layer is then capped with a silicide formed on top of the gate, and conventional formation of the device then proceeds. A second silicide may be employed within the gate.

Optimal Compression Process Selection Methods

A mechanism for determining an optimal compression technique for each data file when creating a computer archive file from a set of data files. A local archiving application receives an instruction to archive a set of data files and determines the file type and size of a data file in the set of data files. An optimal compression method for the data file is selected based on the file type and size of the data file. The archiving application compresses the data file using the optimal compression method. The archiving application updates meta data associated with the compressed file to include a meta compression format identifier of the optimal compression method used to compress the data file. The archiving application then repeats the determining, selecting, compressing, and updating for each data file in the set of data files to create an archive of the set of data files.
