Inna, Second hand input from the field is with deep UV the amount of light is far less than the more normal frequencies. Also the depth of focus is less. This leads to either a move to thinner resist or to Silylation to produce a silicon rich mask in the resist. With Silylation you can produce a silicon rich area where you expose and this helps to create an SiO2 layer in Oxygen plasma. with this you can get plasma development with Oxygen RIE provided the plasma pressure is very low. I like to think of it as the equivalent of a resist M@M with a crisp outer shell of Si and SiO2. Hope this helps.

For instance, what are the most popular deep UV resists used on the market? Who are the manufacturers? Is there something special about deep UV resists processing (special equipment different from what us used for processing of i- and g-line resists)?
