Resist performance factors

The search for quantitative structure-property relationships for the control and prediction of the mechanical behaviour of polymers has occupied a central role in the development of polymer science and engineering. Mechanical performance factors such as creep resistance, fatigue life, toughness and the stability of properties with time, stress and temperature have become subjects of major activity. Within this context microhardness emerges as a property which is sensitive to structural changes. 

It was observed that ECP with high crystallinity formed distinct crystalline lamellar structure in the rubber domains, whereas ECP with low crystallinity did not. The average lamella thickness in the blend of PP/EPR/ECP with high crystallinity was 10-20 nm. The scratch resistance of the surface of these blends was measured since the surface toughness of the products, such as car bumpers, is an important performance factor. The surface resistance usually depends on the...

So far, consideration has been given largely to the chemical factors determining the resist performance. The exposure method and quality of the hardware, however, are fundamental in dictating the type of resist, its many requirements and the quality of images produced. One aspect of this is the chosen irradiation wavelength.
