Methods for high temperature deposition an amorphous carbon film with improved step coverage are provided.

提供了一种以提高的台阶覆盖率高温沉积非晶碳膜的方法。

The films have advantages of slightly compressive stress, very low pin-hole density and superior step coverage.

这种薄膜具有很小的压应力，很低的针孔密度，良好的台阶覆盖性等优点。

Therefore, the substrate temperature was the main factor which obviously affected the atoms distribution and step coverage of Al thin films.

衬底温度决定原子的表面迁移率，衬底温度是影响淀积的铝膜的均匀性和台阶覆盖能力的主要因素。

So we called on insurance companies to step up, provide coverage to our most vulnerable Americans.

WHITEHOUSE: Strengthening Our Health Care Workforce

There is a fear that by taking the unusual step of making a National Coverage Assessment (NCA) of Provenge, Medicare is looking to avoid paying for Provenge at all.
