A mood-interacting shoe device includes a shoe body and an interactive sensing mechanism. The interactive sensing mechanism further includes a heart rate sensor, a speed sensor, a pressure sensor, a microprocessor and a radio frequency emitter. The heart rate sensor senses the heart rate value, the speed sensor senses the marching rate, and the pressure sensor senses the pressure distribution value when the thenar exerts pressure. The sensed values will be transmitted to the microprocessor, where the sensed values are analyzed and thereby the mood of the user is determined accordingly. The analysis result is transmitted to the video and music player through the radio frequency emitter, such that the video and music player can play music corresponding to the mood; and a LED display unit is further provided such that the user can understand whether each sensor operates normally or not.

Structures including a refractory metal collar at a copper wire and dielectric layer liner-less interface, and a related method, are disclosed. In one embodiment, a structure includes a copper wire having a liner-less interface with a dielectric layer thereabove; a via extending upwardly from the copper wire through the dielectric layer; and a refractory metal collar extending from a side of the via and partially along the liner-less interface. Refractory metal collar prevents electromigration induced slit voiding by improving the interface around the via, and prevents void nucleation from occurring near the via. Also, the refractory metal collar provides electrical redundancy in the presence of voids around the via and dielectric layer liner-less interface.
摘要:
An interconnect structure in which the adhesion between an upper level low-k dielectric material, such as a material comprising elements of Si, C, O, and H, and an underlying diffusion capping dielectric, such as a material comprising elements of C, Si, N and H, is improved by incorporating an adhesion transition layer between the two dielectric layers. The presence of the adhesion transition layer between the upper level low-k dielectric and the diffusion barrier capping dielectric can reduce the chance of delamination of the interconnect structure during the packaging process. The adhesion transition layer provided herein includes a lower SiOx— or SiON-containing region and an upper C graded region. Methods of forming such a structure, in particularly the adhesion transition layer, are also provided.

Methods are disclosed for providing stacking fault reduced epitaxially grown silicon for use in hybrid surface orientation structures. In one embodiment, a method includes depositing a silicon nitride liner over a silicon oxide liner in an opening, etching to remove the silicon oxide liner and silicon nitride liner on a lower surface of the opening, undercutting the silicon nitride liner adjacent to the lower surface, and epitaxially growing silicon in the opening. The silicon is substantially reduced of stacking faults because of the negative slope created by the undercut.

A method for reducing dendrite formation in a self-aligned, silicide process for a semiconductor device includes forming a silicide metal layer over a semiconductor substrate, the semiconductor device having one or more diffusion regions, one or more isolation areas and one or more gate structures formed thereon. The concentration of metal rich portions of the metal layer is reduced through the introduction of silicon thereto, and the semiconductor device is annealed.
摘要:
Disclosed is a method for depositing a metal layer on an interconnect structure for a semiconductor wafer. In the method, a metal conductor is covered by a capping layer and a dielectric layer. The dielectric layer is patterned so as to expose the capping layer. The capping layer is then sputter etched to remove the capping layer and expose the metal conductor. In the process of sputter etching, the capping layer is redeposited onto the sidewall of the pattern. Lastly, at least one layer is deposited into the pattern and covers the redeposited capping layer.
