摘要:
In sophisticated integrated circuits, an electronic fuse may be formed such that an increased sensitivity to electromigration may be accomplished by including at least one region of increased current density. This may be accomplished by forming a corresponding fuse region as a non-linear configuration, wherein at corresponding connection portions of linear segments, the desired enhanced current crowding may occur during the application of the programming voltage. Hence, increased reliability and more space-efficient layout of the electronic fuses may be accomplished.

摘要:
Metal fuses in semiconductor devices may be formed on the basis of additional mechanisms for obtaining superior electromigration in the fuse bodies. To this end, the compressive stress caused by the current-induced metal diffusion may be restricted or reduced in the fuse body, for instance, by providing a stress buffer region and/or by providing a dedicated metal agglomeration region. The concept may be applied to the metallization system and may also be used in the device level, when fabricating the metal fuse in combination with high-k metal gate electrode structures.

An electronic fuse may receive a silicon/germanium material in the fuse body, which in turn may result in the formation of a metal silicide material of reduced thickness. Consequently, the current density and, thus, the electromigration and heat generation in the metal silicide material may be increased for a given amount of current. Consequently, transistor switches for applying the programming pulse to the electronic fuse may be reduced in size.

In integrated circuits, resistors may be formed on the basis of a silicon/germanium material, thereby providing a reduced specific resistance which may allow reduced dimensions of the resistor elements. Furthermore, a reduced dopant concentration may be used which may allow an increased process window for adjusting resistance values while also reducing overall cycle times.

An embedded or buried resistive structure may be formed by amorphizing a semiconductor material and subsequently re-crystallizing the same in a polycrystalline state, thereby providing a high degree of compatibility with conventional polycrystalline resistors, such as polysilicon resistors, while avoiding the deposition of a dedicated polycrystalline material. Hence, polycrystalline resistors may be advantageously combined with sophisticated transistor architectures based on non-silicon gate electrode materials, while also providing high performance of the resistors with respect to the parasitic capacitance.
摘要:
In SOI devices, the PN junction of circuit elements, such as substrate diodes, is formed in the substrate material on the basis of the buried insulating material that provides increased etch resistivity during wet chemical cleaning and etch processes. Consequently, undue exposure of the PN junction formed in the vicinity of the sidewalls of the buried insulating material may be avoided, which may cause reliability concerns in conventional SOI devices comprising a silicon dioxide material as the buried insulating layer.
