    • The method comprises depositing a layer (10) of a material (10) on the surface of an article (1) such that the layer (10) covers the mouth of a recess (3) leaving a void below the closed mouth. Subsequently, without elevating their temperature, the article (1) and layer (10) are subjected to elevated pressures (e.g. pressurised liquid) sufficient to cause the layer (10) to deform into the recess (3). Furthermore, the invention provides a method for forming a layer on such a surface, using the technique of magnetron sputtering and heating the article to increase the mobility of the deposited material. Also provided is apparatus for use in carrying out these methods, which methods are of particular use in the processing of semiconductor wafers.
    • 该方法包括在物品(1)的表面上沉积材料(10)的层(10),使得层(10)覆盖凹口(3)的口,在封闭口下方留下空隙。 随后,在不升高其温度的情况下,使物品(1)和层(10)承受足以使层(10)变形成凹部(3)的高压(例如加压液体)。 此外,本发明提供了一种在这种表面上形成层的方法,使用磁控溅射技术和加热制品以增加沉积材料的迁移率。 还提供了用于实施这些方法的装置,哪些方法在半导体晶片的处理中特别有用。
