摘要： A sputtering source having a bias field generated between the substrate and the sputtering source. A conductive louver or grid arrangement is positioned in front of the substrate, and is biased by an RF or DC source. The substrate itself may or may not be biased, as needed. The conductive louvers are rotatable to also function as shutters or collimator to control the flux of the deposited species. The shutter arrangement is mounted onto the sputtering opening of a facing target source (FTS). The shutter is biased by an RF or DC source and the applied power and rotation position of each slat in the shutter are controlled to achieve the desired flux and collimation.

摘要： A deposition system is provided, where conductive targets of similar composition are situated opposing each other. The system is aligned parallel with a substrate, which is located outside the resulting plasma that is largely confined between the two cathodes. A “plasma cage” is formed wherein the carbon atoms collide with accelerating electrons and get highly ionized. The electrons are trapped inside the plasma cage, while the ionized carbon atoms are deposited on the surface of the substrate. Since the electrons are confined to the plasma cage, no substrate damage or heating occurs. Additionally, argon atoms, which are used to ignite and sustain the plasma and to sputter carbon atoms from the target, do not reach the substrate, so as to avoid damaging the substrate.
摘要翻译：提供了一种沉积系统，其中具有相似组成的导电靶位于彼此相对的位置。该系统与衬底平行排列，衬底位于所得到的等离子体的外部，其主要被限制在两个阴极之间。形成“等离子体笼”，其中碳原子与加速电子碰撞并被高度电离。电子被捕获在等离子体笼内，而电离的碳原子沉积在衬底的表面上。由于电子被限制在等离子体笼中，所以不会发生衬底损坏或加热。另外，用于点燃和维持等离子体并从靶上溅射碳原子的氩原子不会到达衬底，以避免损坏衬底。

摘要： A perpendicular magnetic recording medium having a substrate, an amorphous soft underlayer of thickness 30 nm or greater, and a granular magnetic recording layer for perpendicular recording is disclosed. The granular magnetic recording layer includes a non-magnetic region between magnetic grains, wherein the non-magnetic region includes metal nitride or metal carbide and provides exchange decoupling between the magnetic grains. The perpendicular recording medium of this invention reduces DC noise and increases media signal-to-noise ratio; it reduces surface roughness, which in turn reduces the head-to-media spacing and the head-to-amorphous soft underlayer spacing.
