Dry-etching durable resists The real conflict requirement in positive electron resists exists in the relationship between dry-etching durability and sensitivity. Figure 2 depicts this situation. Clearly, aromatic polymers show high durability but low sensitivity (24) Poly(phenylmethacrylate) (PPhMA) withstands reactive sputter-etching more than 2 times longer than... 

In colloquial terminology, plasma etching usually implies conditions that result in rather weak ion bombardment of the wafer. Reactive ion etching (also referred to as reactive sputter etching) implies intense ion bombardment (see Section 4.1). In this Chapter, the term plasma etching will be used throughout. 

Finally, the metallisation layer usually requires patterning, which can be done by reactive ion etching (RIE) or back-sputtering. The two processes are similar. In both techniques accelerated ions hit the substrate and forcibly detach atoms or molecules from the surface. RIE uses reactive gases such as chlorine, Cl or trichlorofluoromethane [75-69-4] CCl E. Inert gases such as argon or neon are used in back-sputtering. 

Fabrication was done by photolithography and deep reactive ion etching (DRIB). The catalyst was inserted by sputtering. Such a prepared microstructure was sealed with a Pyrex cover. The bonded micro device was placed on a heating block containing four cartridge heaters. Five thermocouples monitored temperature on the back side. A stainless-steel clamp compressed the device with graphite sheets. 

A wide variety of process-induced defects in Si are passivated by reaction with atomic hydrogen. Examples of process steps in which electrically active defects may be introduced include reactive ion etching (RIE), sputter etching, laser annealing, ion implantation, thermal quenching and any form of irradiation with photons or particles wih energies above the threshold value for atomic displacement. In this section we will discuss the interaction of atomic hydrogen with the various defects introduced by these procedures.

The reactive ion etching system used for the delineation of tin oxide thin film is a diode RF sputtering system and was described in our earlier paper (8). For tin oxide etching, the etching parameters used are as follows ...
