Traditional Patterning is Complex & Expensive

Traditional patterning methods require multiple complex steps and specialized equipment to selectively remove sections of a thin film layer. By selectively removing part of a thin film layer a pattern is formed by the material that is left behind. However these methods require harsh processing conditions, are expensive, and generate large volumes of hazardous waste.

New patterning technology without these limitations is highly sought after by the electronics industry.

Introducing OTI CPM™ Patterning Technology

CPM™ Patterning is a new technology developed by OTI that uses self-assembly to control the growth of thin films as they form in real time. As a result the CPM™ process works under mild conditions, does not require extra specialized equipment, and does not generate hazardous liquid wastes. The technology has been qualified for mass production by leading manufacturers.

CPM™ Patterning technology is protected by numerous granted and pending patents globally.

CPM™ Technology is Scalable from Nano-to-Macro Scale

CPM Patterning can be used to pattern feature sizes across multiple length scales, making it applicable to multiple markets
