  • Publication number: 20220404710
    Abstract: The present invention relates to a photoresist stripper composition for manufacturing a display, and more particularly, to an integrated photoresist stripper composition which can be used in every process for manufacturing a display. More specifically, the photoresist stripper composition for manufacturing a display according to the present invention can be applied to all of transition metals and oxide semiconductor wirings, and has an excellent ability to remove modified photoresist after a hard bake process, and implant process, and a dry etch process have been performed. In particular, the photoresist stripper composition for manufacturing a display according to the present invention exhibits a corrosion inhibitory effect that has been further specialized for copper (Cu) wiring pattern edge portions which are susceptible to corrosion following dry-etching.

  • Patent number: 8740520
    Abstract: There is provided a beveller for processing an edge of a member to be processed into a slanted surface (a bevel), and, more particularly, to a multi-purpose beveller which improves a level of completion of bevel process through thoroughly processes an edge positioned at a corner by using a beveling tool for a corner mounted onto the beveller and which expands the application fields of the beveller through processing a curved section by simply replacing a rotary cutter for a corner coupled to an adapter with a cutter for a curved section.

  • Patent number: 7635242
    Abstract: The present invention relates to a beveling machine which makes a slanting surface on the edge of a member to be processed, and more particularly, to a beveling machine which is capable of easily controlling the extent of bevel, by minutely controlling the extent of bevel by a simple method of using a bevel-extent controlling unit which is one-touch operated, accurately maintaining the extent of bevel which is automatically controlled at the moment of unloosing the bevel-extent controlling unit which is held, and quickly and easily resetting a reference point of the extent of bevel which is changed after replacing a cutting tip.
