Hmmm…at least shows the US still has an independent judiciary system . Which is something to be commended.

Nah, there's nothing to commend. This is their "reward" for a company agreeing to play by their rules and it hopes to set a precedent that other Chinese companies do so as well under the belief that it isn't a total waste of time, but when it counts, the US courts will always rule against Chinese companies. It's an old scammer's trick. Open up a company; nobody trusts your company because you have no history. Do an amazing job for the first XX clients to build a good reputation so they can spread the word about how awesome the company is. XXXX potential clients drop their guard and send in huge orders to the company, then the nightmares begin. America will never do another commendable thing again until they've woken up and accepted the new reality that China is the new premier power of the world and America can just comfortably and happily cruise at #2; it's not the end of the world and everyone is less stressed.

Conformal polishing of NiP grating microstructures using SiO2/Al2O3 mixed abrasive slurry.​

​

Abstract​

Nickel-phosphorus (NiP) coatings are widely used for surface modification of metal mirrors due to their excellent physical and chemical properties, such as in the collector mirrors of extreme ultraviolet (EUV) lithography machines. Grating microstructures can be fabricated on NiP coatings using Single-Point Diamond Turning (SPDT) to enhance the optical performance of mirrors. However, the SPDT process often introduces periodic marks on the surface, increasing surface roughness, causing optical flux loss, and reducing reflectance, which negatively impact the performance of mirrors. In this study, SiO2/Al2O3 mixed abrasive is employed for Chemical Mechanical Polishing (CMP) to investigate conformal polishing processes for NiP grating microstructures. The mixed abrasive leverages the advantages of both abrasives: Al2O3 abrasive effectively removes periodic marks and reduces the spatial frequency errors in the 101∼102 mm−1 range, while SiO2 abrasive further smooths the surface and reduces the spatial frequency errors in the 102∼103 mm−1 range. Through experiments, factors such as Al2O3 particle size, Al2O3 abrasive concentration, pH, and H2O2 concentration are comprehensively considered to precisely control the synergistic effects of the mechanical removal and chemical reactions of CMP, balancing the optimization of surface quality and conformality of microstructures. By optimizing the polishing slurry and utilizing a combination of soft and hard polishing pads, a uniform RMS roughness of 0.8 nm (scanned area: 218 × 218 μm2) was achieved across a 100 mm diameter NiP grating microstructures sample. Importantly, the grating microstructures retained their shape, with only an 84 nm reduction in the grating height and a 12.98 μm increase in the transition area width after polishing. These results highlight the excellent conformal polishing capability of the process. This study provides a promising strategy for the conformal polishing of large-area and high-precision NiP grating microstructures on EUV collector mirrors, while also offering an important reference for the industrial-scale production of other optical microstructures.​
