NCD Supplied new ALD equipment for protective coating of semiconductor equipment’s products

본문

<Lucida GSH500>

NCD supplied new ALD equipment to the customer based in Korea for coating products used in semiconductor equipment to protect from corrosion and plasma arcing. The customer could expect longer part lifetime and lower operation expense through this special coating because of improving reliability of process and protecting parts from damages.
Productivity and cost competitiveness have been more and more important in semiconductor industry. Using special coating, the competitiveness could be much increased by protecting particle generation and damage of semiconductor production, and cost down by longer maintenance period.

Normally protective coating on parts is used thermal spray coating, anodizing process and sputtering but they have some limitation because it is difficult to coat uniformly on complicated and micro-shaped products by those methods. However ALD process could solve that problem.

Complex shaped shower heads and electro static chucks in the equipment using etching and dry cleaning process with corrosive gases as well as plasma, could be expected to apply ALD process. Because shower heads have a lot of fine holes and ESCs have wafer lift pin holes so those products couldn’t be coated uniformly by CVD and PVD methods. Therefore ALD might be very essential for special coating for these products.

ALD Al2O3 coating to protect part damage is used normally because Al2O3 process has already been confirmed in many application area. ALD Y2O3 will be studied actively for the next protective coating because it has much more anticorrosive property than ALD Al2O3.

This supplied equipment, Lucida GSH500, applied NCD’s creative high throughput and large area ALD technology could load multi semiconductor products at the same time and run uniform ALD coating. NCD will keep our best to develop the more competitive ALD technology and equipment to expand various new application fields in the future.
