Patent number: 9574265Abstract: In some embodiments, the present disclosure relates to a plasma processing system having a magnetron that provides a symmetric magnetic track through a combination of vibrational and rotational motion. The disclosed magnetron has a magnetic element that generates a magnetic field. The magnetic element is attached to an elastic element connected between the magnetic element and a rotational shaft that rotates the magnetic element about a center of the sputtering target. The elastic element may vary its length during rotation of the magnetic element to change the radial distance between the rotational shaft and the magnetic element. The resulting magnetic track enables concurrent motion of the magnetic element in both an angular direction and a radial direction. Such motion enables a symmetric magnetic track that provides good wafer uniformity and a short deposition time.Type: GrantFiled: July 6, 2015Date of Patent: February 21, 2017Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Bo-Hung Lin, Ming-Chih Tsai, You-Hua Chou, Chung-En Kao

Patent number: 9543125Abstract: Plasma-enhanced chemical vapor deposition (PECVD) devices enable the generation of a plasma in a plasma zone of a deposition chamber, which reacts with a surface of a substrate to form a deposited film in the fabrication of a semiconductor component. The plasma generator is often positioned over the center of the substrate, and the generated plasma often remains in the vicinity of the plasma generator, resulting in a thicker deposition near the center than at the edges of the substrate. Tighter process control is achievable by positioning one or more electromagnets in a periphery of the plasma zone and supplying power to generate a magnetic field, thereby inducing the charged plasma to achieve a more consistent distribution within the plasma zone and more uniform deposition on the substrate. Variations in the number, configuration, and powering of the electromagnets enable various redistributive effects on the plasma within the plasma zone.Type: GrantFiled: April 3, 2013Date of Patent: January 10, 2017Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventors: Hsiang-Wei Lin, Chia-Ho Chen, Bo-Hung Lin

Patent number: 9279179Abstract: In some embodiments, the present disclosure relates to a plasma processing system configured to form a symmetric plasma distribution around a workpiece. In some embodiments, the plasma processing system comprises a plurality of coils symmetrically positioned around a processing chamber. When a current is provided to the coils, separate magnetic fields, which operate to ionize the target atoms, emanate from the separate coils. The separate magnetic fields operate upon ions within the coils to form a plasma on the interior of the coils. Furthermore, the separate magnetic fields are superimposed upon one another between coils to form a plasma on the exterior of the coils. Therefore, the disclosed plasma processing system can form a plasma that continuously extends along a perimeter of the workpiece with a high degree of uniformity (i.e., without dead spaces).Type: GrantFiled: February 6, 2012Date of Patent: March 8, 2016Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Ming-Chin Tsai, Bo-Hung Lin, Chung-En Kao, Chin-Hsiang Lin

Patent number: 9026241Abstract: The present disclosure relates to semiconductor tool monitoring system having multiple sensors configured to concurrently and independently monitor processing conditions of a semiconductor manufacturing tool. In some embodiments, the disclosed tool monitoring system comprises a first sensor system configured to monitor one or more processing conditions of a semiconductor manufacturing tool and to generate a first monitoring response based thereupon. A redundant, second sensor system is configured to concurrently monitor the one or more processing conditions of the manufacturing tool and to generate a second monitoring response based thereupon. A comparison element is configured to compare the first and second monitoring responses, and if the responses deviate from one another (e.g., have a deviation greater than a threshold value) to generate a warning signal. By comparing the first and second monitoring responses, errors in the sensor systems can be detected in real time, thereby preventing yield loss.Type: GrantFiled: February 24, 2012Date of Patent: May 5, 2015Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Wen-Cheng Yang, Chung-En Kao, You-Hua Chou, Ming-Chih Tsai, Chen-Chia Chiang, Bo-Hung Lin, Chin-Hsiang Lin

Patent number: 8884526Abstract: In some embodiments, the present disclosure relates to a plasma processing system that generates a magnetic field having a maximum strength that is independent of workpiece size. The plasma processing system has a plurality of side electromagnets that have a size which is independent of the workpiece size. The side electromagnets are located around a perimeter of a processing chamber configured to house a semiconductor workpiece. When a current is provided to the side electromagnets, separate magnetic fields emanate from separate positions around the workpiece. The separate magnetic fields contribute to the formation of an overall magnetic field that controls the distribution of plasma within the processing chamber. Because the size of the plurality of separate side magnets is independent of the workpiece size, the plurality of side magnets can generate a magnetic field having a maximum field strength that is independent of workpiece size.Type: GrantFiled: January 20, 2012Date of Patent: November 11, 2014Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Bo-Hung Lin, Ming-Chih Tsai, Chia-Ho Chen, Chung-En Kao
