1. A method of forming a lithographic mask comprising the steps of:
- in a computer system, generating a lithographic mask design file by the steps comprising;
(a)(i) inputting sequence information into said computer system, said sequence information defining monomer addition steps in a molecular synthesis wherein each monomer addition step is associated with at least one opening location in a mask design of said lithographic mask;
(a)(ii) identifying open locations in said mask design of said lithographic mask and joining said open locations in said mask design of said lithographic mask to form a joined location, said open locations defining flash locations for forming said lithographic mask, said joined location defining a larger flash location for forming said lithographic mask;
(a)(iii) outputting said mask design file, said mask design file defining locations for openings in said lithographic mask, wherein at least one flash location in said mask design file corresponds to a joined location; and
(b) with a computer-controlled system, forming said lithographic mask according to said mask design file, whereby at least some flash locations on said lithographic mask are connected.

2. A method of forming a lithographic mask comprising the steps of:
-
in a computer system, generating a lithographic mask design file by the steps comprising; (a)(i) inputting sequence information into said computer system, said sequence information defining monomer addition steps in a molecular synthesis wherein each monomer addition step is associated with at least one opening location in a mask design of said lithographic mask; (a)(ii) identifying a first rectangular flash location as an open location in said mask design of said lithographic mask; (a)(iii) evaluating an adjacent rectangular location to determine if said adjacent location is an open location and, if said adjacent location is an open location, connecting it with said first rectangular flash location to form a joined rectangular flash opening; (a)(iv) outputting said mask design file, said mask design file defining locations for openings in said lithographic mask, wherein a flash location in said mask design file corresponds to said joined rectangular flash opening; and (b) with a computer-controlled system, forming said lithographic mask according to said mask design file, whereby at least one flash location on said lithographic mask is connected. - View Dependent Claims (3, 4)
