Abstract
Semiconductor devices may be made by forming a silicided layer on a silicon material such as that used to form the extractor of a field emission display. The silicided layer may be self-aligned with the emitter of a field emission display. It the silicided layer is treated at a temperature above 1000° C. by exposure to a nitrogen source, the silicide is resistant to subsequent chemical attack such as that involved in a buffered oxide etching process.
Claims4
A method for forming a field emission display comprising the steps of:
- forming an extractor;
- forming a coating on said extractor to prevent light from passing through said extractor;
- and
- treating said coating to make said coating resistant to chemical attack.
