UV Tapes; Help Protect Surface of Semiconductor Wafer during Back Grinding Process

 

UV Tapes

UV tapes (dicing tapes) are pressure-sensitive tapes used to hold wafer strongly during wafer back-grinding or wafer dicing process. These tapes have high adhesion strength. UV tapes are made up of Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), or Polyolefin (PO) backing product along with acrylic adhesive to hold pieces of semiconductor in correct place. UV tapes are adhesive tape for semiconductor process and are also used in the glass dicing applications. UV tapes help protect the wafer (temporarily) from surface damage and surface scratching during the fabrication, storage, and shipping of semiconductor wafers.

UV tapes are also applicable for various work pieces such as sapphire, glass, ceramics, etc. These tapes are pressure-sensitive tapes in which the adhesive bond breaks after exposure to UV light, making the adhesive strong during cutting while allowing clean and easy removal. UV tapes are useful during distribution, storage, and manufacturing of semiconductor wafers as they help protect wafers from surface scratching and surface damage. UV tapes hold semiconductor pieces during the cutting process and mount them to a thin metal frame.

UV tapes are extensively used in the electronics industry for glass dicing applications, PCB grinding, back grinding, and wafer dicing. The most appropriate condition for UV tape varies by wafer surface condition, type of UV lamp, and tape grade. These tapes offer specific features and properties that allow them to work well in direct sunlight and other demanding external environments. Semiconductors are the brains of modern electronics, enabling highly advanced technologies in computing, communications, transportation, and healthcare, among many other applications.

Thus, with the growing demand for semiconductor goods worldwide, the demand for UV tapes is also increasing. According to the U.S., Semiconductor Industry Association (SIA), the global semiconductor sales increased 6.5% in 2020, demonstrating growing demand for chips across a range of end markets.
