摘要:
A dual damascene process and structure for fabricating semiconductor devices are disclosed. In one embodiment of the invention, a protection layer is deposited on top of a metal layer to protect the metal layer during subsequent etching of an oxide layer to form the via and damascene trench. Because the selectivity between the oxide layer and the protection layer is high, the number and complexity of processing steps are thereby reduced. Other embodiments of the present invention use a metal sealant layer and/or anti-reflective coating in conjunction with the protection layer in a dual-damascene process.

One aspect of the present invention relates to a method for reducing resist residue defects on a wafer structure. The method involves providing a semiconductor structure having a photoresist, the photoresist comprising open areas and circuit areas thereon; irradiating the open areas and circuit areas through a first photomask with a first energy dose to effect an image-wise pattern in the photoresist; irradiating the open areas of the photoresist through a second photomask with a second energy dose; and developing the photoresist.

A system for monitoring and/or controlling an etch process associated with a dual damascene process via scatterometry based processing is provided. The system includes one or more light sources, each light source directing light to one or more features and/or gratings on a wafer. Light reflected from the features and/or gratings is collected by a measuring system, which processes the collected light. The collected light is indicative of the etch results achieved at respective portions of the wafer. The measuring system provides etching related data to a processor that determines the desirability of the etching of the respective portions of the wafer. The system also includes one or more etching devices, each such device corresponding to a portion of the wafer and providing for the etching thereof. The processor produces a real time feed forward information to control the etch process, in particular, terminating the etch process when desired end points have been encountered.

The present invention provides systems, methods, and standards for calibrating nano-measuring devices. Calibration standards of the invention include carbon nanotubes and methods of the invention involve scanning carbon nanotubes using nano-scale measuring devices. The widths of the carbon nanotube calibration standards are known with a high degree of accuracy. The invention allows calibration of a wide variety of nano-scale measuring devices, taking into account many, and in some cases all, of the systematic errors that may affect a nano-scale measurement. The invention may be used to accurately calibrate line width, line height, and trench width measurements and may be used to precisely characterize both scanning probe microscope tips and electron microscope beams.

A system for monitoring and controlling a boron phosphorous doped silicon oxide (BPSG) deposition and reflow process is provided. The system includes one or more light sources, each light source directing light to one or more portions of a wafer upon which BPSG is deposited. Light reflected from the BPSG is collected by a measuring system, which processes the collected light. Light passing through the BPSG may similarly be collected by the measuring system, which processes the collected light. The collected light is indicative of the conformality of the BPSG deposition of the respective portions of the wafer. The measuring system provides BPSG deposition related data to a processor that determines the BPSG deposition of the respective portions of the wafer. The system also includes a plurality of reflow controlling devices, each such device corresponding to a respective portion of the wafer and providing for the heating and/or cooling thereof. The processor selectively controls the reflow controlling devices so as to regulate temperature of the respective portions of the wafer.

A system for monitoring and controlling aperture etching in a complimentary phase shift mask is provided. The system includes one or more light sources, each light source directing light to one or more apertures etched on a mask. Light reflected from the apertures is collected by a measuring system, which processes the collected light. Light passing through the apertures may similarly be collected by the measuring system, which processes the collected light. The collected light is indicative of the depth and/or width of the openings on the mask. The measuring system provides depth and/or width related data to a processor that determines the acceptability of the aperture depth and/or width. The system also includes a plurality of etching devices associated with etching apertures in the mask. The processor selectively controls the etching devices so as to regulate aperture etching.
