MKS has won significant business from a Korean end-user for ALD high flow of ozone systems

Since basically the start of ALD in high volume DRAM manufacturing on 300 mm wafers, ozone has been employed as the co-reactant for ALD of hafnia and zirconia based high-k node dielectrics in the DRAM capacitor memory cell. The ozone concentration directly controls through-put, uniformity and conformalty of the deposited high-k and most importantly also the high-k dielectric performance of the layer including CET/Leakage performance and log term reliability. Please see this early post on details for these processes (LINK)

Just recently MKS Instruments reported (Seeking Alpha Earnings call transcript, LINK) that they won significant business from a Korean end-user for a high flow of ozone systems used in atomic layer deposition to fabricate DRAM memory devices. In addition, MKS reported to have just received a significant suppler award from another major Korean OEM.

MKS further stated that they have made strategic investments with a significant impact on their semiconductor OEM and end-user businesses. Amazingly, the revenue in Korea has increased 250% since 2012. In 2017 alone, their Korea end-user business grew 114%, while the Korea OEM business grew 96%.

Based on this we may assume that high concentration ozone supply i still crucial for the ALD oxide processes in DRAM manufacturing.
