HMDS Vapour Phase Substrate Coating Oven, Vacuum HMDS Vapour Phase Oven, HMDS Furnace
In the photolithography process of integrated circuit manufacturing, to ensure better graphic transfer during wafer processing, it is necessary to first apply an HMDs pre-treatment process to the wafer. This replaces the hydrophilic surface of the wafer with hydrophobic, achieving a contact angle of 65 degrees or higher on the wafer surface.
HMDS can be directly spun onto the wafer by rotating the diluted solution, and allows for the rotation to dry (HMDS is highly volatile at room temperature). Inadequate drying of HMDS can result in significant loss of adhesion. Although direct spinning is straightforward, it is effective only when displacing a small portion of the alcohol groups. To date, the preferred method for applying an adhesive agent is to place the substrate in an HMDS vapor, typically under elevated temperature and reduced pressure. This allows for good coating of the substrate without excessive HMDS deposition, and higher temperatures lead to better reaction. After proper treatment with HMDS, the substrate can be stored for several days without significant reabsorption of moisture.
