The 25.4mm size is a commonly used size for research and development, as it allows for the production of smaller quantities of devices at a lower cost compared to larger wafer sizes. The smaller size also allows for more flexibility in the design and layout of the devices, as it allows for a higher level of integration on a single wafer.
Silicon wafers are used in a wide range of applications, including electronics, optoelectronics, and photovoltaics. They are also used in the production of sensors, actuators, and other microelectromechanical devices. In addition to their use in the microelectronics industry, silicon wafers are also used in the biomedical field for applications such as tissue engineering and drug delivery.
Below is just a small inventory of our 25.4mm silicon wafers that we have in stock and ready to ship.
| Note: Surface - P = Polished, E = Etched, C = AsCut, G = Ground, Ox = Oxide (on that surface); Material - CZ unless noted Note: Items sold in quantities of 25, unless noted |
