    Abstract: A system and method for repairing a photolithographic mask is provided. An embodiment comprises forming a shielding layer over an absorbance layer on a substrate. Once the shielding layer is in place, the absorbance layer may be repaired using, e.g., an e-beam process to initiate a reaction to repair a defect in the absorbance layer, with the shielding layer being used to shield the remainder of the absorbance layer from undesirable etching during the repair process.

    Abstract: A deflecting plate includes a silicon-on-insulator (SOI) substrate. The SOI substrate includes: an insulator layer having a top surface and a bottom surface; a device layer coupled to the insulator layer at the top surface, wherein multiple deflecting apertures are disposed in the device layer, each of which extending from a top open end to a bottom open end through the device layer, and wherein the bottom open end is coplanar with the top surface of the insulator layer; and a handle substrate coupled to the insulator layer at the bottom surface, wherein a cavity is disposed in the handle substrate and extends from a cavity open end to a cavity bottom wall, and wherein the bottom wall is coplanar with the top surface of the insulator layer, such that the bottom open end of each deflecting aperture is exposed to the cavity.

    Abstract: Structure of mask blanks and masks, and methods of making masks are disclosed. The new mask blank and mask comprise a tripe etching stop layer to prevent damages to the quartz substrate when the process goes through etching steps three times. The triple etching stop layer may comprise a first sub-layer of tantalum containing nitrogen (TaN), a second sub-layer of tantalum containing oxygen (TaO), and a third sub-layer of TaN. Alternatively, the triple etching stop layer may comprise a first sub-layer of SiON material, a second sub-layer of TaO material, and a third sub-layer of SiON material. Another alternative may be one layer of low etching rate MoxSiyONz material which can prevent damages to the quartz substrate when the process goes through etching steps three times. The island mask is defined on the mask blank by using various optical proximity correction rules.
