    • An apparatus and method provide deposition on a surface by angled sputtering using a collimation grid having angled vanes which limit the distribution of trajectories of particles in at least one coordinate direction around a central axis oriented at an angle of less than 90.degree. to said surface; resulting in improved uniformity of deposition and/or selective favoring of deposition on surfaces at a high angle to the deposition surface (e.g. sidewalls). Substantially parallel orientation and uniform spacing of the sputtering target and deposition surface provides good uniformity of results over the deposition surface. The angled trajectories of sputtered particles provides improved deposition on sides of upstanding mandrel features and filling of recessed features of high aspect ratio, especially when the collimation grid is rotated about an axis generally perpendicular to the deposition surface. Angled, collimated deposition also allows for control of deposition at potentially sub-lithographic feature sizes by using portions of features as a mask with deposition being performed only on remaining exposed portions of features or deposition on selected sides of a mandrel feature. Sidewall image transfer techniques may thus be extended to non-symmetrical and singular features. At very shallow angles to the deposition surface, deposited material has a fibrous texture with greatly increased effective surface area.
    • 一种装置和方法通过使用具有成角度的叶片的准直栅格通过成角度的溅射来提供沉积在表面上,所述准直网格限制了颗粒在至少一个坐标方向上的轨迹的分布,所述中心轴线围绕所述表面以小于90°的角度定向; 导致沉积的均匀性和/或选择性地有利于在沉积表面(例如侧壁)上以高角度沉积在表面上。 溅射靶和沉积表面的基本平行取向和均匀间隔提供了超过沉积表面的结果的良好均匀性。 溅射颗粒的倾斜轨迹提供了直立心轴特征的侧面上的改进的沉积以及高纵横比的凹陷特征的填充,特别是当准直格栅围绕大致垂直于沉积表面的轴线旋转时。 倾斜的准直沉积还允许通过使用特征部分作为掩模来控制潜在的亚光刻特征尺寸下的沉积,仅在特征的剩余暴露部分或沉积在心轴特征的选定侧上进行沉积。 因此,侧壁图像传送技术可以扩展到非对称和奇异的特征。 与沉积表面非常浅的角度,沉积材料具有大大增加的有效表面积的纤维织构。

    • A semiconductor device or other suitable substrate and method with single or multi layers of buried micro pipes are disclosed. This is achieved by controlling the aspect ratio of trenches as well as controlling the deposition characteristics of the material used to fill the trenches. A buried micro pipe is formed by filling a trench that has a height which is larger than a width thereof, so that the trench filler material lines sidewalls and bottom of the trench, and covers the top of the trench to form the micro pipe within the trench. Another layer can be formed over the filler material and planarized. Alternatively, the filler material itself can be planarized. Forming trenches in the planarized layer, and repeating the above steps forms a second set of buried micro pipes in these new trenches. This forms a semiconductor device having multiple layer of buried micro pipes. Via holes may be etched to contact a micro pipe, or to inter connect micro pipes buried at different levels. Thus, instead of eliminating defective voids in trenches, the voids are controlled to form the micro pipes, which may be used to circulate a cooling fluid, or lined with a conductive material to form a micro light pipe channel, or buried conductive pipes.
    • 公开了一种具有单层或多层埋入微管的半导体器件或其它合适的衬底和方法。 这通过控制沟槽的纵横比以及控制用于填充沟槽的材料的沉积特性来实现。 通过填充具有大于其宽度的高度的沟槽而形成埋入的微管,使得沟槽填充材料管道沟槽的侧壁和底部,并且覆盖沟槽的顶部以在该沟槽内部形成微管 沟。 可以在填料材料上形成另一层并进行平面化。 或者,填充材料本身可以被平坦化。 在平坦化层中形成沟槽,并重复上述步骤,在这些新的沟槽中形成第二组埋入的微管。 这形成具有多层埋藏微管的半导体器件。 可以蚀刻通孔以接触微管,或者将不同层次的微管相互连接。 因此,不是消除沟槽中的有缺陷的空隙,而是控制空隙以形成可用于循环冷却流体或用导电材料衬里以形成微光管通道的微管或埋入的导电管。
