Description
Technical Field
The invention relates to the technical field of semiconductor equipment, in particular to a bearing device and semiconductor equipment.
Background
At present, in semiconductor processing equipment, a mechanical chuck is generally used for bearing a highly warped substrate, a bonded substrate and an insulating substrate, and can be applied to a normal-temperature sputtering process of semiconductor processing to bear a wafer.
In the existing semiconductor processing equipment, a base assembling device, a pressure ring and a mechanical chuck are generally arranged in a process chamber, wherein the mechanical chuck comprises a tray arranged on the base assembling device and used for bearing a wafer, and a clamping ring arranged around the tray. When a sputtering deposition process is carried out, the upper surfaces of the wafer, the clamping ring and the pressure ring are exposed in the environment of plasma and are bombarded by charged particles, wherein the upper surface of the wafer can accumulate charges due to poor conductivity of the material, the clamping ring and the pressure ring are usually made of metal materials and are connected with the base assembling device through the tray, so that the charges on the upper surfaces of the clamping ring and the pressure ring can be freely migrated and released, and therefore, a potential difference is generated between the upper surface of the wafer and the upper surface of the clamping ring, a sparking (point discharge) phenomenon occurs between the edge of the wafer and the clamping ring, and a series of serious consequences such as damage to the wafer, excessive particles and poor process performance are caused.
In order to avoid the sparking phenomenon, the pressing ring is pressed against the edge area of the upper surface of the wafer during the sputtering deposition process, so that the charges on the upper surface of the wafer can be released through free migration of the pressing ring, and the potential difference between the wafer and the clamping ring is reduced.
However, since the edge region of the upper surface of the wafer is pressed by the pressing ring, the edge region cannot be deposited during the sputtering deposition process, thereby affecting the subsequent processes (such as electroplating). Moreover, during the continuous process, the heat accumulated on the pressure ring can be transferred to the wafer, which causes the temperature at the edge of the wafer to be too high, thereby affecting the process performance. In addition, in some apparatuses such as Physical Vapor Deposition (PVD), when a rf bias is applied to the susceptor assembly, most of rf energy is introduced to the edge portion of the wafer through the pressure ring, and only a small amount of rf energy is applied to the middle portion of the wafer through the susceptor, so that the rf energy density applied to the wafer is gradually reduced from the edge to the center of the wafer, resulting in a large influence on the uniformity of film Deposition.
