  • Patent number: 7531275
    Abstract: A photomask assembly and method for protecting the photomask assembly from contaminants generated during a lithography process are disclosed. A photomask assembly includes a pellicle assembly formed from a pellicle frame and a pellicle film coupled to a first surface of the pellicle frame. The pellicle frame further includes an inner wall and an outer wall. A photomask is coupled to a second surface of the pellicle frame opposite the pellicle film. A molecular sieve that prevents airborne molecular contaminants (AMCs) generated during a lithography process from contaminating the photomask is associated with the pellicle assembly.

  • Patent number: 7425393
    Abstract: A phase shift photomask and method for improving printability of a structure on a wafer are disclosed. The method includes providing a photomask including a zero degree PSW formed on a top surface of a substrate and a 180 degree PSW formed in a first region of the substrate. An orthogonal PSW that facilitates projection of an increased intensity of radiant energy through a second region of the substrate during a lithography process is formed in the second region between the zero degree PSW and the 180 degree PSW.

  • Patent number: 7398509
    Abstract: A computer network for generating instructions for photomask manufacturing equipment, based on photomask specification data input by a customer. A series of order entry screens are downloaded to a remote customer's computer, typically via an internet connection. The customer is prompted to enter photomask specification data, which is delivered to computing equipment on the manufacturer's local network. The manufacturer's computing equipment validates the photomask specification data, and uses this data to generate fracturing instructions and equipment control instructions. The fracturing instructions, together with pattern design data from the customer, are delivered to a fracture engine, which provides fractured pattern data. The control instructions and the fractured pattern data may then be electronically delivered to the manufacturing equipment.

  • Patent number: 7277159
    Abstract: A system and method for automatically mounting a pellicle assembly on a photomask are disclosed. The method includes loading a photomask into a mounting apparatus and loading a pellicle assembly into a back plate of the mounting apparatus opposite the photomask. The back plate includes at least one load cell that measures a force applied by the mounting apparatus to the photomask and the pellicle assembly. The measured force associated with the at least one load cell is received and the pellicle assembly is mounted on the photomask to create a photomask assembly if the measured force is greater than or approximately equal to a minimum force.

  • Patent number: 6978437
    Abstract: A photomask for eliminating antenna effects in an integrated circuit and integrated circuit manufactured with the photomask are disclosed. The photomask includes a substrate and a patterned layer formed on at least a portion of the substrate. The patterned layer may be formed using a mask pattern file created by analyzing a pattern in a mask layout file to identify a region including an antenna ratio less than a first design rule. A feature located in the identified region is moved based on a second design rule from a first position to a second position in the mask layout file to create a space in the identified region. A grounding feature is placed in the space and automatically connected to a gate feature in the mask layout file such that the antenna ratio is increased to greater than or approximately equal to the first design rule.
