  • Patent number: 7785754
    Abstract: A method of repairing a photomask with a depression defect includes providing a photomask including a depression defect on a transparent substrate, forming a protection layer which covers the depression defect, etching a predetermined depth of the transparent substrate of the photomask with the protection layer as the etch mask, and removing the protection layer and the transparent substrate under the unetched protection layer, wherein a defect free photomask is produced.

  • Publication number: 20100119710
    Abstract: An apparatus and a method according to example embodiments is capable of patterning ink on a substrate by using dip-pen nanolithography regardless of the interaction between the ink and the substrate. The patterning apparatus may includes a heat supply control device. The heat supply control device may supply heat so as to liquefy the ink and facilitate the patterning of the ink on the substrate. The melting point of the ink may be set within the predetermined temperature controlled by the heat supply control device.

  • Patent number: 7521156
    Abstract: A photo mask for use in forming a pattern, such as a photoresist pattern, is corrected to compensate for discrepancies in the transmissivity of the photo mask which results in the pattern having a distribution of critical dimensions that is too great or which deviates too much from the target critical dimension of the pattern. The photo mask includes a transparent substrate, a light-shielding layer pattern defining transmission sites on the transparent substrate, and at least some of which sites have a relatively low transmissivity. The method of correcting the photo mask includes doping a front surface of the transparent substrate of the photo mask with ions. A predetermined number of the sites can be doped to narrow the distribution of the critical dimensions of the pattern formed using the photo mask, or all of the transmission sites of the photo mask can be doped to make the average of the critical dimensions of the pattern closer to the target critical dimension of the pattern.
