Used AMAT / APPLIED MATERIALS Centura 4.0 DPN Gate Stack #293812988 for sale

AMAT Centura 4.0 DPN Gate Stack is a chemical vapor deposition (CVD) reactor for fabricating advanced integrated circuits. It is a multi-chamber equipment that allows for the deposition of a range of materials, including state-of-the-art silicides, dielectrics, metal contacts, and passivated gate oxides. The system is equipped with a robust gas management unit to accurately control pressure and flow. The reactor also features a temperature control unit allowing for precise temperature control in all chambers. The temperature control is further enhanced by the high resolution temperature sensors distributed throughout the machine. The Centura 4.0 is also equipped with a state-of-the-art loadlocks to ensure uniformity of the process chamber, and features low substrate capacitance for improved repeatability and reduced charging. In the deposition process, a chamber is pre-loaded with a wafer carrier and then pumped down to a specified pressure, generally below 50 milliTorr. The wafer substrate is tranfered into the load lock and the transfer chamber is closed to create an isolated environment. Gases are introduced and all flows are accurately sensed and monitored. Temperature and pressure are then regulated to ensure uniformity throughout the chamber, and the process chemistry is initiated. Various materials used in integrated circuits can then be deposited onto the wafer substrate based on the deposition parameters. This includes: silicides, dielectrics, metal contacts, and passivated gate oxides, as well as high-k dielectrics. These materials are coaxially monitored to ensure that the desired temperature is achieved, and it is also possible to monitor concentrations of some process gases, such as silane, to ensure a proper reaction. Once the process has been completed, the wafer is released from the transfer chamber and loaded into a wafer transporter, ready for shipping or final metrology. The Centura 4.0 DPN Gate Stack gives engineers and scientists the ability to quickly and effectively fabricate advanced integrated circuits, resulting in higher yields and improved performance.
