high-temperature processes relate to materials development for corrosion resistance at hightemperatures, high-temperature
membrane and separation processes, heat exchangers, and heat storage media. Design aspects and safety are also important for high-temperature processes.
-Thermo-chemical water splitting
For example, Thermo-chemical water splitting is the conversion of water into hydrog
hightemperatures. For safety reasons, all activities in the RCA clean procedure should be performed in a Clean Station Work Area which is located under an exhaust fume hood.
[Figure 1] RCA cleaning
the RCA clean proceedure consists of the following steps
: Chemical Storage ⇒ Mix Organic Solution ⇒ Mix Ionic Solution ⇒ Mix HF Solution ⇒ Set-Up Bubbler Rinse
Ⅰ. INTRODUCTION
In fourth semester most of our department students attend the subject of mechanical manufacturing practice and we have made a bolt by ourselves. But the process was not a soft job. A bolt and nut is used diversely but it seemed that we don't know much about a importance and manufacture of bolts.
A bolt is a threaded fastener used in industry to make two or more mechanical

4. Fluid handling system
materials to be used in processing for CMOS devices
Process compatibility - for one, the film must survive sufficiently hightemperatures such as a Rapid thermal anneal to 1000 °C for say, 10 s (as dictated by the CMOS technological process)
Reliability
Stability against degradation by the electric field and injected carriers.
