    摘要: 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.

    摘要: In some embodiments, the present disclosure relates to a plasma processing system comprising a magnetron configured to provide a symmetric magnetic track through a combination of vibrational and rotational motion. The disclosed magnetron comprises a magnetic element configured to generate a magnetic field. The magnetic element is attached to an elastic element connected between the magnetic element and a rotational shaft configured to rotate magnetic element about a center of the sputtering target. The elastic element is configured to 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.

    摘要: 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.

    摘要: 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).

    摘要: The present disclosure is directed to a physical vapor deposition system configured to heat a semiconductor substrate or wafer. In some embodiments the disclosed physical vapor deposition system comprises at least one heat source having one or more lamp modules for heating of the substrate. The lamp modules may be separated from the substrate by a shielding device. In some embodiments, the shielding device comprises a one-piece device or a two piece device. The disclosed physical vapor deposition system can heat the semiconductor substrate, reflowing a metal film deposited thereon without the necessity for separate chambers, thereby decreasing process time, requiring less thermal budget, and decreasing substrate damage.
