摘要:
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.
摘要:
In a semiconductor device, optical signal transfer capabilities are implemented on the basis of silicon-based monolithic opto-electronic components in combination with an appropriate waveguide. Thus, in complex circuitries, such as microprocessors and the like, superior performance may be obtained in terms of signal propagation delay, while at the same time thermal requirements may be less critical.
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:
A method for formally verifying the equivalence of an architecture description with an implementation description. The method comprises the steps of reading an implementation description, reading an architecture description, demonstrating that during execution of a same program with same initial values an architecture sequence of data transfers described by the architecture description is mappable to an implementation sequence of data transfers implemented by the implementation description, such that the mapping is bijective and ensures that the temporal order of the architecture sequence of data transfers corresponds to the temporal order of the implementation sequence of data transfers, and outputting a result of the verification of the equivalence of the architecture description with the implementation description.
摘要:
Deep drain and source regions of an N-channel transistor may be formed through corresponding cavities, which may be formed together with cavities of a P-channel transistor, wherein the lateral offsets of the cavities may be adjusted on the basis of an appropriate reverse spacer regime. Consequently, the dopant species in the N-channel transistor extends down to a specific depth, for instance down to the buried insulating layer of an SOI device, while at the same time providing an efficient strain-inducing mechanism for the P-channel transistor with a highly efficient overall manufacturing process flow.

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.

By providing a CMP stop layer in a metal gate stack, the initial height thereof may be efficiently reduced after the definition of the deep drain and source areas, thereby providing enhanced process conditions for forming highly stressed dielectric materials. Consequently, the dielectric material may be positioned more closely to the channel region substantially without deteriorating gate conductivity.
摘要:
In a replacement gate approach in sophisticated semiconductor devices, the placeholder material of gate electrode structures of different type are separately removed. Furthermore, electrode metal may be selectively formed in the resulting gate opening, thereby providing superior process conditions in adjusting a respective work function of gate electrode structures of different type. In one illustrative embodiment, the separate forming of gate openings in gate electrode structures of different type may be based on a mask material that is provided in a gate layer stack.

In sophisticated semiconductor devices, the threshold voltage adjustment of high-k metal gate electrode structures may be accomplished by a work function metal species provided in an early manufacturing stage. For this purpose, a protective sidewall spacer structure is provided, which is, in combination with a dielectric cap material, also used as an efficient implantation mask during the implantation of extension and halo regions, thereby increasing the ion blocking capability of the complex gate electrode structure substantially without affecting the sensitive gate materials.
