    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.

    Abstract: A method for reducing layer overlay errors by synchronizing the density of mask material in the frame area across the masks in a set is disclosed. An exemplary method includes creating a mask design database corresponding to a mask and containing a die area with one or more dies and a frame area outside the die area. Fiducial features within the frame area are identified, and from the fiducial features, an idle frame area is identified. A reference mask design, which corresponds to a reference mask configured to be aligned with the mask, is used to determine a reference density for the idle frame area. The idle frame area of the mask design database is modified to correspond to the reference density. The modified mask design database is then available for further use including manufacturing the mask.

    Abstract: A metal-oxide-semiconductor (MOS) device having a selectable threshold voltage determined by the composition of an etching solution contacting a metal layer. The MOS device can be either a p-type or n-type MOS and the threshold voltage is selectable for both types of MOS devices. The etching solution is either an oxygen-containing solution or a fluoride-containing solution. The threshold voltage is selected by adjusting the flow rate of inert gases into an etching chamber to control the concentration of oxygen gas or nitrogen trifluoride.
