Used OAI (Exposure Systems) for sale

OAI (Optical Associates Inc.) is a renowned manufacturer of advanced exposure equipment used in the semiconductor and microelectronics industry. Their exposure systems use cutting-edge optical technology to transfer intricate patterns onto silicon wafers during the photolithography process. One of the main analogues of OAI's exposure units is their use of proximity exposure, also known as projection lithography. This technique involves placing a mask or photomask very close to the wafer, and light is transmitted through the mask to create the desired pattern. This proximity exposure method ensures high precision and accuracy in transferring patterns onto the silicon wafer. One of the advantages of OAI's exposure machines is their ability to achieve sub-micron resolution, making them ideal for manufacturing small-scale and intricate electronic components. These tools also offer high throughput, allowing for faster production cycles and increased productivity. OAI's exposure assets have been widely adopted by leading semiconductor manufacturers worldwide. Examples of their exposure models include the Model 358, Model 306, and Model 0130-067934. These models offer a range of features such as multiple exposure modes, automatic mask alignment, and advanced control equipment. In conclusion, OAI's exposure systems are renowned for their proximity exposure technique, high resolution, and high throughput capabilities. With their advanced features and wide adaptation in the industry, OAI continues to be a trusted choice for semiconductor manufacturers looking for reliable and efficient exposure units.
