The relentless advancement in semiconductor technology demands materials with ever-increasing precision and performance. Hexamethyldisilazane (HMDS), a versatile organosilicon compound, plays a critical role in this sector, particularly as an adhesion promoter for photoresists during photolithography. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the importance of HMDS in enabling sophisticated microelectronic fabrication and are dedicated to supplying high-quality HMDS to meet these demands.

In semiconductor manufacturing, the process of photolithography involves transferring circuit patterns onto silicon wafers using photoresist materials. For this intricate process to be successful, the photoresist must adhere uniformly and strongly to the wafer surface. Silicon wafers inherently possess hydrophilic hydroxyl (-OH) groups on their surface. These groups can cause issues like poor adhesion, leading to pattern defects and reduced device yield. HMDS effectively addresses this challenge.

When applied to the silicon wafer surface, HMDS reacts with these surface hydroxyl groups, replacing them with hydrophobic trimethylsilyl (TMS) groups. This surface modification renders the wafer hydrophobic, creating an ideal interface for the subsequent application of the photoresist. The TMS layer dramatically improves the adhesion of the photoresist to the wafer, preventing undercutting and ensuring precise pattern replication. This enhanced adhesion is crucial for achieving high-resolution features and maximizing the yield of complex integrated circuits.
