摘要:
Fail sites in a semiconductor are isolated through a difference image of a fail area and a healthy area. The fail area comprises an image of a semiconductor with a fail. The healthy area comprises an image of a semiconductor absent the fail or, in other words, an image of a semiconductor with healthy structure. Instructions cause a variation in the intensities of the difference image to appear at the fail site.

A structure is provided with a metal cap for back end of line (BEOL) interconnects that substantially eliminates electro-migration (EM) damage, a design structure and a method of manufacturing the IC. The structure includes a metal interconnect formed in a dielectric material and a metal cap selective to the metal interconnect. The metal cap includes RuX, where X is at Boron, Phosphorous or a combination of Boron and Phosphorous.
摘要:
A metal interconnect structure includes at least a pair of metal lines, a cavity therebetween, and a dielectric metal-diffusion barrier layer located on at least one portion of walls of the cavity. After formation of a cavity between the pair of metal lines, the dielectric metal-diffusion barrier layer is formed on the exposed surfaces of the cavity. A dielectric material layer is formed above the pair of metal lines to encapsulate the cavity. The dielectric metal-diffusion barrier layer prevents diffusion of metal and impurities from one metal line to another metal line and vice versa, thereby preventing electrical shorts between the pair of metal lines.

A method of monitoring and testing electro-migration and time dependent dielectric breakdown includes forming an addressable wiring test array, which includes a plurality or horizontally disposed metal wiring and a plurality of segmented, vertically disposed probing wiring, performing a single row continuity/resistance check to determine which row of said metal wiring is open, performing a full serpentine continuity/resistance check, and determining a position of short defects.

A metal resistor and resistor material and method of forming the metal resistor are disclosed. The metal resistor may include an infused metal selected from the group consisting of: copper (Cu) infused with at least one of silicon (Si), nitrogen (N2), carbon (C), tantalum (Ta), titanium (Ti) and tungsten (W), and aluminum infused with at least one of silicon (Si), nitrogen (N2), carbon (C), tantalum (Ta), titanium (Ti) and tungsten (W). The method is less complex than conventional processes, allows control of the resistance by the amount of infusion material infused, and is compatible with conventional BEOL processes.

The invention predicts premature dielectric breakdown in a semiconductor. At least one dielectric breakdown mode is calculated for the semiconductor wafer. If a one mode is calculated, premature dielectric breakdown will be associated with any semiconductor with a breakdown voltage less than a predetermined standard deviation of a plurality of breakdown voltages within said calculated mode. If multiple modes are calculated, the mode that most accurately represents dielectric breakdown for the semiconductor wafer is determined and premature dielectric breakdown will be associated with any semiconductor with a breakdown voltage less than a predetermined standard of the calculated mode that most accurately represents dielectric breakdown for the semiconductor wafer.
摘要:
A method of fabricating a semiconductor device having a dielectric structure on which an interconnect structure is optionally patterned using lithographic and etching techniques, within a single deposition chamber, is provided. The dielectric structure may optionally be covered by diffusion barrier materials prior to a sputter etching process. This sputter etching process is used to remove the native oxide on an underneath metal conductor surface and includes a directional gaseous bombardment with simultaneous deposition of metal neutral. Diffusion barrier materials may also be deposited into the pattern.

A BEOL e-fuse is disclosed which reliably blows in the via and can be formed even in the tightest pitch BEOL layers. The BEOL e-fuse can be formed utilizing a line first dual damascene process to create a sub-lithographic via to be the programmable link of the e-fuse. The sub-lithographic via can be patterned using standard lithography and the cross section of the via can be tuned to match the target programming current.
