In electronics, large crystal of silicon is used as the basis for semiconductor computer chips and switching devices for electric grid applications. The efficiency of electronic devices is dependent on the perfection of the crystals as it offers better control of electron flow without loss. Different types of semiconductor crystals, like diamond, can outperform silicon but are essentially unavailable for use. The current project proposes to use artificial intelligence on the data generated and collected during crystal growth to predict parameters instead of trial and error for growth of defect free crystals. The use artificial intelligence will assess the data generated during the growth process itself, the current state of crystal growth, and predict the growth results. Development and integration of deep learning artificial intelligence architectures in the Chemical Vapor Deposition process will make growth predictions more accurate and add defect assessment to the prediction for manufacturing of diamond material System. Outcome of the project will accelerate the development cycles and reduce costs for manufacturing processes which will be adaptable to a broad range of crystal growth processes for electronics. Concepts developed in the project will be integrated into existing courses, capstone projects will be designed for students, and education modules will be developed for training operators. A course in data collection, handling, and interpretation will be developed for vocational workers to understand, adapt, and team with artificial intelligence augmented manufacturing machines in the work environment. The course will be disseminated to manufacturing community by partnering with the Automation Alley, an industry manufacturing consortium.The proposed project will design and develop a holistic artificial intelligence platform to solve the problems of traditional approaches for growth of large-scale crystalline diamond material system. The approach will focus on increasing the resolution of image collection and training the program to resolve problems with spatio-temporal data, including: (1) checkerboard artifacts, (2) lack of photo-realism, and (3) inability to prevent feature loss, while maintaining a large frame resolution. Further, the artificial intelligence architectures developed for this project will be merged into solutions for frame prediction based on input time series parameters like temperature and defects to achieve state-of-the-art accuracy metrics in growth state prediction. The large scale and defect free diamond material system is one of the most challenging and holds the promise of revolutionizing power device technology. The enhanced predictive capabilities proposed in this project derived from higher resolution images and incorporation of microscope defect data will enable in-process control of the evolving growth process for diamond and will lead the way for fully automated process control of crystal growth processes for manufacturing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在电子领域，大硅晶体被用作半导体计算机芯片和电网应用开关装置的基础。电子设备的效率取决于晶体的完美程度，因为它可以更好地控制电子流而不会造成损失。不同类型的半导体晶体（例如金刚石）的性能可以优于硅，但基本上无法使用。当前的项目建议利用人工智能在晶体生长过程中生成和收集的数据来预测参数，而不是反复试验来生长无缺陷晶体。使用人工智能将评估生长过程本身产生的数据、晶体生长的当前状态，并预测生长结果。化学气相沉积过程中深度学习人工智能架构的开发和集成将使生长预测更加准确，并将缺陷评估添加到金刚石材料系统制造的预测中。 该项目的成果将加快开发周期并降低制造工艺的成本，这将适用于广泛的电子晶体生长工艺。该项目中开发的概念将整合到现有课程中，将为学生设计顶点项目，并为培训操作员开发教育模块。 将为职业工人开发一门数据收集、处理和解释课程，帮助他们在工作环境中理解、适应人工智能增强制造机器并与之合作。该课程将通过与工业制造联盟 Automation Alley 合作向制造界传播。拟议项目将设计和开发一个整体人工智能平台，以解决传统方法生长大型结晶金刚石材料系统的问题。该方法将侧重于提高图像采集的分辨率并训练程序来解决时空数据的问题，包括：（1）棋盘伪影，（2）缺乏照片真实感，以及（3）无法在保持大帧分辨率的同时防止特征丢失。此外，为该项目开发的人工智能架构将被合并到基于温度和缺陷等输入时间序列参数的帧预测解决方案中，以在生长状态预测中实现最先进的准确度指标。大规模且无缺陷的金刚石材料系统是最具挑战性的系统之一，并且有望彻底改变功率器件技术。该项目提出的增强预测能力源自更高分辨率的图像和显微镜缺陷数据的结合，将能够对不断发展的金刚石生长过程进行过程控制，并将引领制造晶体生长过程的全自动过程控制。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
