Cleaning wafers that have been used by customers are collected,the dummy wafer and the adhesive sheet separated, and the dummy wafer reused after cleaning. A fabrication method for dicing semiconductor wafers using laser cutting techniques, which can effectively prevent the devices on semiconductor die units from the phenomenon of etching undercut caused by the sequential steps after laser cutting, comprises following steps: covering the wafer surface with a protection layer; dicing the wafer by laser and separating the die units from each other. During the mounting process there is contact at the wafer face only around the SEMI Specified non active edge area, absolutely safe for bumped wafers. Sapphire processing services Rokko provides an integrated sapphire wafer processing service (Grinding → Polishing → RCA cleaning) through the well-developed technologies. Wafer Polishing Cleaning Grinding Dicing and Bonding. Cleaning Jet: ~1. Wafer / Substrate Cleaning Pac Tech offers the peripheral equipment associated with electroless plating, including: plasma clean (PlasPac) and megasonic solvent cleaning (MegaPac). Wafer de-taping tape 3305 is used to peel the UV adhesive from the wafer (Fig. • Dicing ferrites, glasses and piezoelectrics. Exhaust Air Systems. After the dicing We also provide "removal of protective film for dicing (such as resist)" and "cleaning" as well. The next step that follows is the use of RCA. Wafer Expanding System Model EXM-06M This model is to pickup diced devices on tape easier. The diesaw can also be used to create small dies from a new wafer as starting material for processing. The solvent resistance dicing tape can support very thin wafers during the solvent cleaning process and it can be diced afterword. Syagrus Systems is a leader in post-fab for semiconductor and electronic components by providing silicon wafer backgrinding, wafer dicing, die inspection and sorting, and SMD Tape and Reel. Brush Module 2. It is a multi-functional tape that transfers an adhesive layer to the backside when a die is picked. The following is the products for your reference. The product contained a release coating on the polymer support film in order to allow for clean release of the conductive adhesive layer with the chip when the latter was removed from the support film after dicing of the wafer. wafer thickness reductions are needed but require new dicing methods to avoid yield loss at the stage where the wafer value is the highest or even worse when a broken die would yield out a package containing 10 or more dies. The conventional saw dicing technology is preventing the ongoing trend for thin wafer. Wafer Cleaning There are a number of wafer cleaning techniques or steps employed to ensure that a semiconductor wafer is always free of contaminants and foreign materials as it undergoes the wafer fabrication process. The dicing process can involve scribing and breaking, mechanical sawing (normally with a machine called a dicing saw) or laser cutting.
