A method for manufacturing a semiconductor device includes forming a contact etch stop layer on an active area of a substrate that has a gate stack formed thereon. The gate stack includes a metal gate and a metal oxide. The contact etch stop layer includes a silicon oxide layer sandwiched between a first silicon nitride layer and a second silicon nitride layer that is disposed on the active area. The method further includes forming a contact hole extending through an interlayer dielectric layer on the first silicon nitride layer using the first silicon nitride layer as a protection for the active area, removing a portion of the first silicon nitride layer disposed at the bottom of the contact hole using the silicon oxide layer as a protection for the active area, and removing the metal oxide using the second silicon nitride layer as a protection for the active area.

摘要:
The present invention belongs to the field of biomedical material, and is particularly related to a method of preparing bioactive glass coatings by liquid precursor thermal spray. The objective of the present invention is to overcome the shortcomings of the air plasma spraying where the powder feedstock preparation is complicated and time-consuming, and sol-gel or other wet chemistry method where the synthesized coating generally has thin coating thickness and with low production efficiency. Therefore, a new method is provided for preparation of bioactive glass coatings. In this method, organic and inorganic raw materials were first weighed in accordance with the chemical composition of bioactive glasses, and sol or suspension was prepared; then the sol or suspension was used as the feedstock for thermal spray, and was deposited on the biomedical materials substrate, at high temperature to form the bioactive glass coating. The invention possesses the following advantages: simple operation, less complicated procedures, synthesis with high efficiency, low production cost, suitable for industrial production, and so on. This method can be used to prepare bioactive glass coatings.
