Semiconductors have truly become a familiar and necessary part of daily life. Semiconductors will need to offer increased functionality in order to process and utilize the huge amounts of big data that will be generated with the arrival of the age of IoT. These components are expected to continue to grow thinner and denser. Higher grade cutting and separation (dicing) of IC chips from wafers will be required to meet these needs, and a variety of manufacturing methods are already being proposed.
In conventional manufacturing processes, mechanical methods are used to dice wafers into several IC chips. However, in order to obtain chips with better yields and improved quality, methods in which it is made easier for wafers to be broken into chips (such as using a laser to form a modifying layer inside the wafer) and in which wafers are separated and cut by expanding semiconductor tape applied to wafers in a radial direction are gaining recent attention.
Furukawa Electric has begun mass producing expand separation dicing tape, a type of tape for use with semiconductors. In addition to not breaking even under high speed/high pull expansion conditions subject to heavy loads, expand separation dicing tape offers uniform expansion without any internal stretching (“necking”), allowing for wafers to be separated in excellent condition regardless of chip size. The product also offers excellent expansion and preservation characteristics between chips, helping to significantly reduce process machining time. Die attach film (DAF), a crucial component in mounting semiconductor chips, can also be separated and cut along with the chips, resulting in reliable pickup functionality.
Product Features & Data/Specifications
- In addition to separating wafers via expansion using semiconductor tape, the product offers superior DAF separation and expansion/preservation characteristics between chips, allowing for simple pickup.
- Comes in a roll shape with circular DAF attached to dicing tape. Standard length of 100 m/roll; tape thickness varies by type (100 to 200 μm).
