Radiation properties, change during

The thermal decomposition of the resist photoactive compound or radiation-sensitive components during prebake is modeled using first-order kinetics this often results in a change in the resist s optical properties, mostly the Dill A and B parameters. ... 

Poly(sulfone) has the characteristic properties such as chemical inertness, excellent strength, stiffness, high resistance to radiations and temperature, dimensional stability, and biocompatibility [2,16,56], These properties resemble the properties of light metals [57], Further, the properties of poly(sulfone) do not change during... 

As drying proceeds, the material that is dried suffers a change in its radiation properties, increasing its reflectivity, and consequently lowering its absorptivity at low water contents. It is then possible to change adequately the temperature of the emitter in order to improve the absorption of radiation during drying. 

Figure 5.24 Property changes in PE-LD films (180pm thick) stabilized with HALS and Ni-quenchers during exposure in a greenhouse compared to open-air exposure (Saudi Arabia, total radiation energy 5.75 10 W h/rrf) according to ASTM D 1435 [65]...
