摘要： Aluminum or aluminum alloy sputter targets and methods of making same are provided. The pure aluminum or aluminum alloy is mechanically worked to produce a circular blank, and then the blank is given a recrystallization anneal to achieve desirable grain size and crystallographic texture. A 10-50% additional strain is provided to the blank step after the annealing to increase the mechanical strength. Further, in a flange area of the target, the strain is greater than in the other target areas with the strain in the flange area being imparted at a rate of about 20-60% strain. The blank is then finished to form a sputtering target with desirable crystallographic texture and adequate mechanical strength.
摘要翻译： 提供铝或铝合金溅射靶及其制造方法。 对纯铝或铝合金进行机械加工以产生圆形坯料，然后将坯料进行再结晶退火，以获得所需的晶粒尺寸和晶体织构。 在退火之后向坯料步骤提供10-50％的附加应变以增加机械强度。 此外，在靶的凸缘区域中，应变大于在其他目标区域中的应变，其中凸缘区域中的应变以约20-60％应变的速率施加。 然后将坯料完成以形成具有所需晶体学结构和足够的机械强度的溅射靶。

摘要： A method of making a diffusion bonded sputter target assembly is provided. A target blank comprising a first metal or alloy has a first surface defining a sputtering surface and a second surface. A second metal or alloy is placed around the target blank. A backing plate is provided adjacent the second metal or alloy that is positioned alongside of the second target surface. This assembly is then diffusion bonded, and a portion of the second metal overlying the sputtering surface of the target is removed to expose the target sputtering surface. W target or W alloy target/Ti or Ti alloy backing plate assemblies are provided with an Al interlayer positioned intermediate the W or W alloy target and backing plate. The assembly has a bond strength exceeding 50 MPa.

摘要： A non-planar sputter target having differing crystallographic orientations in portions of the sputter target surface that promote more desirable deposition and density patterns of material sputtered from the target surface onto a substrate. A closed dome end of the sputter target is comprised of a first crystallographic orientation and sidewalls of the sputter target are comprised of a crystallographic orientation different from that of the dome. The sputter target is formed, preferably by hydroforming or other metal working techniques, in the absence of annealing. The hydroforming manipulations result in the different crystallographic orientations while minimizing, or ideally omitting, the application of heat. Quick and cost effective non-planar sputter targets that are easily repeatably producable are achievable as a result.

摘要： A vacuum seal having an O-ring between two mating parts. One of the mating parts has a groove configured to receive the O-ring. The groove has a modified dovetail shape with at least one side wall having a compound slope formed with a first portion forming an angle of less than 90 degrees with respect to a base wall and a second portion extending substantially perpendicular to the sealing face of the mating part. The cross-sectional area of the groove is less than 95% of the cross sectional area of the O-ring and the width of the groove mouth is at least 94% of the diameter of the O-ring.
