Discuss the reasons for the low resistivity of silicon core materials in reduction furnaces
Thread Content
Let’s discuss the reasons for the low resistivity of silicon cores in reduction furnaces. The resistivity of silicon cores in our company is often below 10; please share your insights on this topic.
Is it N-type or P-type? The resistivity is mainly related to the B content; it is recommended to test the B content of the trichlorosilane impurities
Reply to 2# cjzhx123: They are all N-type now; when P-type ones were available, the resistivity was higher
We have encountered this situation here as well; N-type ones are used more often. Since the silicon cores are produced in batches, this situation will improve over time. Basically, it only has a slight impact when starting up the furnace; there’s no difference in the later stages
