The chemical nature of plasma dicing produces only gaseous by-products which are removed by vacuum pumping leaving a clean wafer surface, critical in applications such as hybrid bonding. Mechanical dicing or laser ablation can result in debris or particulate contamination across the wafer surface (which can be … See more Plasma dicing removes the material in the dicing lane chemically. There is no mechanical damage, no heat affected zones or other physical impact on the die. This means that plasma dicing causes no damage. Die, … See more Blade dicing and laser dicing are “serial” processes cutting along the dicing lanes one after the another. For laser, specifically, multiple passes may be needed. Plasma dicing removes all the dicing lanes “in … See more As the wafer layout is not constrained by the need to have linear dicing paths, plasma dicing can offer device designers much greater … See more Without any physical restrictions such as blade width, or laser spot size, to accommodate plasma can enable a move to narrower dicing lanes, providing an opportunity to … See more WebThis all contributes to lower die yield per wafer. Modern applications are moving towards thinner wafers to enable more technology in smaller volumes. Plasma dicing, with gentle but high-speed etching, makes an impact on advanced packaging. Several approaches are available for plasma dicing, and all are suitable for thick or thin wafers.
Ultra-thin Wafer Fabrication Through Dicing-by-Thinning
WebAug 23, 2024 · For traditional thickness wafers, dicing was typically accomplished by physical means - using a saw or blade, various grits, and water as the die were physically separated. With thin wafers, three options for dicing include not only physical (cutting) technology, but also laser techniques and plasma dicing. Mechanical Dicing WebSep 21, 2024 · 2.1 Experimental material. Experiments used a 12 in. dummy sample wafer with a final grinding thickness of 200 µm, A Disco DFD-6361 (Disco Co.) dicing machine with a 6.00 (mm) × 8.00 (mm) die was used, with a dicing tape thickness of 110 µm, and UV type adhesion layer material, popularly two kind of dicing type, one is UV type other is Non-UV … twitch fugu
