摘要:
In one embodiment, a method of manufacturing a semiconductor device includes using a processor to generate a first three dimensional (3-D) resist profile for a first process condition using an layout mask of a target structure. The method further includes using a processor to generate a second 3-D resist profile for a second process condition using the layout mask. The first process condition includes a plurality of process variables, and the second process condition includes different values of the plurality of process variables than the first process condition. The method includes generating a 3-D process variable (PV) band profile by combining the first 3-D resist profile with the second 3-D resist profile and displaying a 3-D image of the 3-D PV band profile on a display.

A stray light feedback system and method for a lithography exposure tool. The stray light feedback helps control critical dimension (CD) within a stray light specification limit. A stray light dose control factor is calculated as a function of the stray light measured in the exposure tool and the sensitivity of the resist. The stray light dose control factor is used to adjust the exposure dose to achieve the desired CD. The stray light may be monitored, and if a threshold level of stray light is reached or exceeded, the use of the exposure tool may be discontinued for a particular type of semiconductor product, resist, or mask level, until the lens system is cleaned.

Disclosed herein is an automatic fluid dispensing method and system for dispensing fluid on the surface of a plate-like material, or substrate, including a semiconductor wafer for imprint lithography processes. The dispensing method uses fluid dispenser and a substrate stage that may generate relative lateral motions between a fluid dispenser tip a substrate. Also described herein are methods and devices for creating a planar surface on a substrate using a substantially unpatterned planar template.

Exemplary embodiments include a method for edge correction in pattern recognition, the method including receiving a design layout, receiving a sample plan based on the design layout, receiving user-generated edge input and generating a recipe output from the design layout, the sample plan and the user-generated edge input. The incorporation of the edge input results in SEM recipes that are much more successful in recognizing patterns that have tendency to deviate in appearance from design by, for example, moderate to severe sidewall angle.

Described are imprint lithography templates, methods of forming and using the templates, and a template holder device. An imprint lithography template may include a body with a plurality of recesses on a surface of the body. The body may be of a material that is substantially transparent to activating light. At least a portion of the plurality of recesses may define features having a feature size less than about 250 nm. A template may be formed by obtaining a material that is substantially transparent to activating light and forming a plurality or recesses on a surface of the template. In some embodiments, a template may further include at least one alignment mark. In some embodiments, a template may further include a gap sensing area. An imprint lithography template may be used to form an imprinted layer in a light curable liquid disposed on a substrate. During use, the template may be disposed within a template holder. The template holder may include a body with an opening configured to receive the template, a support plate, and at least one piezo actuator coupled to the body. The piezo actuator may be configured to alter a physical dimension of the template during use.

Methods of forming a mask for implanting a substrate and implanting using an implant stopping layer with a photoresist provide lower aspect ratio masks that cause minimal damage to trench isolations in the substrate during removal of the mask. In one embodiment, a method of forming a mask includes: depositing an implant stopping layer over the substrate; depositing a photoresist over the implant stopping layer, the implant stopping layer having a density greater than the photoresist; forming a pattern in the photoresist by removing a portion of the photoresist to expose the implant stopping layer; and transferring the pattern into the implant stopping layer by etching to form the mask. The implant stopping layer may include: hydrogenated germanium carbide, nitrogenated germanium carbide, fluorinated germanium carbide, and/or amorphous germanium carbon hydride (GeHX), where X includes carbon. The methods/mask reduce scattering during implanting because the mask has higher density than conventional masks.
