Strong demand for thinner wafers and smaller die is driving the evolution of dicing technologies
Demand for thinned wafers is growing strongly!
Driven by consumer applications such as smartphones, smart cards and stacked packages, the demand for thinned wafers has increased over recent years.
We estimate that the number of thinned wafers used for MEMS devices, CMOS Image Sensors, memory and logic devices, including those with TSVs, as well as and Power devices exceeded the equivalent of 16.5 million 8-inch wafer starts per year (WSPY) in 2015. This is mainly supported by CMOS Image Sensors, followed by Power devices. We expect that this number of thinned wafers will peak at the equivalent of almost 32 million 8-inch WSPY by 2020. This would represent a 14% compound annual growth rate (CAGR) from 2015 to 2020.
Thinner wafers bring several benefits, including enabling very thin packaging, and therefore better form factors, improved electrical performance and high heat dissipation.
Miniaturization towards smaller, higher-performing, lower-cost device configurations has thinned wafers below 100 µm or even 50 µm for some applications, such as memory and power devices.
Forecasts for the number of thinned wafers by thickness and by application are analyzed in this report. It also includes insights on the number of thinning tools, breakdowns by wafer size, and technological highlights affecting the applications mentioned above...
