    摘要: A substrate with a patterned opaque coating formable into an opaque aperture in one process is provided. The opaque coating includes at least a bottom layer and a top layer. The bottom and top layers each include a material selected from the group consisting of chrome and chrome oxide. The top layer has a compressive stress, which makes the opaque coating more resistant to pinhole formation during downstream processing.

    摘要: A substrate includes an opaque chrome coating on a surface of the substrate dry-etched to form an aperture, wherein chrome in the aperture is below detectable limit. A method of forming an opaque chrome coating having at least two layers on a substrate includes depositing an initial chrome layer having a thickness of less than 10 nm on the substrate without ion-assist or with undetectable ion-assist, and then depositing the remainder of the at least two layers, with or without ion-assist, to form an opaque chrome coating.

    摘要: Disclosed is a process for making thin hard pellicle for photomasks used in projection photolithography. The process can be used for making thin hard pellicles comprising a pellicle layer having a thickness in the range of about 5 to 120 μm and a mount frame attached to the peripheral area of a surface of the pellicle layer. The pellicle layer can consist essentially of a material selected from silica, fluorine doped silica, aluminum doped silica, methylated silica, fluorinated and methylated silica, fluorinated aluminum doped silica, CaF2, MgF2, BaF2 and SiC. The mount frame is preferred to have substantially the same CTE of the pellicle layer to minimize stress caused by temperature change. The mount frame is preferred to be porous to the purging gas. The process for making the hard pellicle involves deposition of an intermediate layer comprising a hydrogenated amorphous silicon layer on a flat substrate, deposition of the pellicle layer on the intermediate layer, mounting the frame to the pellicle layer and the separation of the pellicle from the substrate by heat treatment.

    摘要: The invention is directed to a process of purifying metal fluoride materials used to make metal fluoride single crystals suitable for making optical elements used in the transmission of wavelengths below 200 nm, and in particular to a process of purifying such materials by the use of a halogen containing plasma to convert metal oxygenates contaminating the feedstocks used in the preparation of the crystals to metal fluorides. The invention also is directed to a process of growing a metal fluoride single crystal using a crystal growth furnace to carry out the foregoing purification procedure followed by the steps of melting the purified material and cooling it using s selected time and temperature cycle to from a metal fluoride single crystal. The plasmas used in practicing the invention can be derived from a variety of halogenated materials including, for example, fluorocarbons, chlorocarbons, boron trihalides, chlorine, fluorine, xenon difluoride and other gaseous or easily volatilized halogenated substances known in the art.
