Hiperetch™
eXPertise & PartnersHiP
Merck supports the Display industry with the background of more than 100 years of experience in high technology products, e.g. Liquid Crystals. The local expertise and global competence cover development, application know-how, manufacturing expertise and worldwide market presence. As reliable partner we develop tailor-made, innovative structuring concepts for our partners in the display manufacturing business, e.g. touchpanel.
innoVation & QUalitY
With the isishape™ concept Merck offers a broad range of innovative structuring materials that simplifies the processes and enables environmentally friendly production, high utilization and production speed.
The isishape™ concept is recommended particular for production of new generation Touchpanel, Flexible displays, OLEDs, EL backlights and others.

The Screen Printing of isishape™ etching pastes is an efficient and high throughput process. In comparison to other removal techniques such as laser ablation or lithography it provides lower operating and investment costs. Moreover it does neither cause particles nor damages the substrate surface.
isishape™ structures layers of nearly all types of transparent conductive oxides, nitride or oxygen compound materials (e.g. SiO2, SiNx), semiconductors (e.g. a-Si, poly-Si) and metals (e.g. aluminium)

enVironment & Waste Water
Being environmentally friendly, isishape™ products support the green factory concept because they contain lowest concentrations of etching species and organic solvents. Due to the very good material utilisation the water consumption in the cleaning process is minimal. In addition cleaning and rinsing in DI water does not require organic detergents. Both leading to extremely low COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand) values.
