摘要:
In a replacement gate approach, the semiconductor material or at least a significant portion thereof in a non-transistor structure, such as a precision resistor, an electronic fuse and the like, may be preserved upon replacing the semiconductor material in the gate electrode structures. To this end, an appropriate dielectric material may be provided at least prior to the removal of the semiconductor material in the gate electrode structures, without requiring significant modifications of established replacement gate approaches.
摘要:
In a replacement gate approach, a spacer may be formed in the gate opening after the removal of the placeholder material, thereby providing a superior cross-sectional shape upon forming any electrode metals in the gate opening. Moreover, the spacer may be used for reducing the gate length, while not requiring more complex gate patterning strategies.

In a stacked semiconductor device, a Peltier element may be incorporated as a distributed element so as to provide active heat transfer from a high power device into a low power device, thereby achieving superior temperature control in stacked device configurations. For example, a CPU and a dynamic RAM device may be provided as a stacked configuration, wherein waste heat of the CPU may be efficiently distributed into the low power memory device.

When forming sophisticated high-k metal gate electrode structures, the removal of a dielectric cap material may be accomplished with superior process uniformity by using a silicon dioxide material. In other illustrative embodiments, an enhanced spacer regime may be applied, thereby also providing superior implantation conditions for forming drain and source extension regions and drain and source regions.

In sophisticated transistor elements, integrity of sensitive gate materials may be enhanced while, at the same time, the lateral offset of extension regions may be reduced. To this end, at least a portion of the extension regions may be implanted at an early manufacturing stage, i.e., in the presence of a protective liner material, which may, after forming the extension regions, be patterned into a protective spacer structure used for preserving integrity of the sensitive gate electrode structure.
摘要:
In sophisticated semiconductor devices, replacement gate approaches may be applied in combination with a process strategy for implementing a strain-inducing semiconductor material, wherein superior proximity of the strain-inducing semiconductor material and/or superior robustness of the replacement gate approach may be achieved by forming the initial gate electrode structures with superior uniformity and providing at least one cavity for implementing the strained channel regions in a very advanced manufacturing stage, i.e., after completing the basic transistor configuration.
摘要:
Sophisticated high-k metal gate electrode structures are provided on the basis of a hybrid process strategy in which the work function of certain gate electrode structures is adjusted in an early manufacturing stage, while, in other gate electrode structures, the initial gate stack is used as a dummy material and is replaced in a very advanced manufacturing stage. In this manner, superior overall process robustness in combination with enhanced device performance may be achieved.

摘要:
When forming a sophisticated high-k metal gate stack in an early manufacturing stage, the dielectric cap layer may be efficiently removed without unduly affecting the drain and source extension regions. To this end, a specifically designed sidewall spacer structure may be used, such as a silicon dioxide spacer element in combination with a silicon nitride etch stop liner. The spacer structure may thus enable the removal of the dielectric cap layer while still maintaining the functions of an implantation mask and a silicidation mask during the further processing.
