摘要： A method for planarizing metal plugs for device interconnections. The process begins by providing a semiconductor structure with at least one device thereon. A dielectric layer is formed over the device and the semiconductor structure. A first barrier metal layer is formed on the dielectric layer, and a sacrificial oxide layer is formed on the first barrier metal layer. The sacrificial oxide layer, the first barrier metal layer, and the dielectric layer are patterned to form contact openings. A second barrier metal layer is formed over the semiconductor structure, and a metal contact layer is formed on the second barrier metal layer. The metal contact layer and the second barrier metal layer are planarized using a first chemical mechanical polishing process and the sacrificial oxide layer is removed. The metal contact layer and the first barrier metal layer are planarized using a second chemical mechanical polishing process.

摘要： A method of manufacturing a shallow trench isolation using a polishing step with reduced dishing. A pad layer, a polish stop layer, a buffer layer and a hard mask layer are formed over a substrate. The hard mask layer has a hard mask opening. We etch a trench opening in the buffer layer, the polish stop layer, the pad layer and form a trench in the substrate using the hard mask layer as an etch mask. We form an oxide trench liner layer along the sidewalls of the trench and an oxide buffer liner layer on the sidewalls of the buffer layer using a thermal oxidation. The hard mask layer prevents the oxidation of the top surface of the buffer layer during the oxidation of the oxide trench liner. This prevents the buffer layer from being consumed by the oxidation and leaves the buffer layer to act in the subsequent chemical-mechanical polish (CMP) step. Next, an insulating layer is formed at least partially filling the trench. The insulating layer is chemical-mechanical polished using the polish stop layer as a stop layer. The buffer layer acts to prevent field oxide dishing during the chemical-mechanical polish.

摘要翻译： 使用具有减少的凹陷的抛光步骤制造浅沟槽隔离的方法。 在衬底上形成焊盘层，抛光停止层，缓冲层和硬掩模层。 硬掩模层具有硬掩模开口。 我们使用硬掩模层作为蚀刻掩模，在缓冲层，抛光停止层，焊盘层中蚀刻沟槽开口，并在衬底中形成沟槽。 我们使用热氧化沿着沟槽的侧壁和缓冲层的侧壁上的氧化物缓冲衬垫层形成氧化物沟槽衬里层。 硬掩模层防止在氧化物沟槽衬垫的氧化期间缓冲层的顶表面的氧化。 这防止缓冲层被氧化消耗，并使缓冲层在随后的化学 - 机械抛光（CMP）步骤中起作用。 接下来，形成至少部分地填充沟槽的绝缘层。 绝缘层使用抛光停止层作为停止层进行化学机械抛光。 缓冲层用于防止化学机械抛光过程中的场氧化物凹陷。

摘要： An example device includes a U-shaped body to be placed around a guide on which a scanner carriage is to be guided. A fixed leg of the U-shaped body is attached to a linearly translatable scanner carriage. A free leg of the U-shaped body is not attached to the scanner carriage and has inward facing ribs. The ribs on the free leg of the U-shaped body are positioned to come into contact with the guide to align the scanner carriage with the guide.

摘要： The present invention provides a clock and data recovery circuit, including an n-phase clock, a sampling and edge detection unit, an edge determination unit, a clock picking unit and a data picking unit. The sampling and edge detection unit performs spaced sampling on the input serial data using the n-phase clock, and performs edge detection and resampling on the sampled data. The edge determination unit filters the resampled data by the counting units, and obtains the positions of the edges of the serial data according to the counting result of the counting units. The clock picking unit selects a clock from the n clocks that is the farthest away from the edges as the recovered clock. The data picking unit obtains the recovered data according to the recovered clock. The present invention also provides a parallel output circuit.

摘要： Storage class memory may be used in an architecture to achieve high performance, high reliability, high compatibility. In some embodiments, reads may be handled in a conventional way used in a memory based model. However writes do not use a memory based model but instead correspond to a storage based model. The hybrid nature can be achieved by setting the storage class memory to be write protected so that all writes must go through a software based block device interface. In some embodiments, the software based block device interface prevents erroneous writes to the storage class memory.
