About the job

As a Resolution Enhancement Techniques (RET) modeling engineer youll create and optimize OPC models for Texas Instruments most advanced technology nodes. Models will include both lithography and etch-based models. Responsibilities will include but are not limited to:

• Partnering with design process engineering and process integration teams to define design shapes needed for building accurate models.
• Designing parameterized mask layouts needed for model building inputs.
• Investigating and implementing ML and AI methods for improving model accuracy and runtime.
• Implementing advanced optimization techniques.
• Working with process engineering and process integration teams on wafer verification to validate model quality.
• Working with OPC verification engineers to improve the accuracy of post-OPC verification models. These include but are not limited to weak image assist feature printing and resist top-loss models.
• Troubleshooting photolithographic patterning related issues related to OPC modeling for all fabs within TI.
• Developing and maintaining a suite of model quality checks for unit testing. These include but are not limited to grid checks stability tests OPC convergence tests and ghost contour checks.
• Developing models that can support multi-patterning approaches such as SADP and LELE.

The person performing this role must be capable to plan effectively drive schedules meet critical deadlines on multiple tasks in parallel lead technical discussions in their area of expertise and work effectively across organizational boundaries. They must be able to clearly communicate project status and actions. Additionally they must be able to interface with multiple organizations and work well on a diverse team to accomplish goals.
