An additional use of polyimide resin is as an insulating and passivation layer in the manufacture of digital semiconductor and MEMS chips.
43.
In DRIE of polymers, Bosch process with alternating steps of SF 6 etching and C 4 F 8 passivation take place.
44.
The passivation layer required to prevent CNT oxidation may reduce the optical transparency of the electrode region and lower the photovoltaic efficiency.
45.
Glass frit as a dielectric material does not need additional passivation for preventing leakage currents at process temperatures up to 125 �C.
46.
A thin insulating layer is formed to achieve surface passivation via the attachment of polymeric materials on CQDs surface treated by acid.
47.
Figure 2 shows an example of a CPB fabricated by Intel and incorporated into their passivation layer at the top of the picture.
48.
In one study, the silicon surface is washed with ammonium hydrogen fluoride leaving it covered with silicon hydrogen bonds ( hydride passivation ).
49.
These industry standards generally list several passivation processes that can be used, with the choice of specific method left to the customer and vendor.
50.
With cryogenic RIE, the low temperature and oxygen gas achieve this sidewall passivation by forming, easily removed from the bottom by directional ions.
