  • Method of growing epitaxial layers from a liquid phase
    Patent number: 4373988
    Abstract: A rotary head is provided with supply chambers near the center of rotation ommunicating with slot-like channels extending radially to a surrounding annular space. Substrates are set into holders, such as dovetail guides in the channel walls to expose surfaces to the liquid that flows by through the channels from the supply chambers when the head is set into rotation. The used liquid, after it reaches the annular space, flows down into a catch basin at the bottom of a surrounding casing, which casing also has an opening at the top for loading the supply chambers.
