I believe the answer is:

semiconductor

I'm a little stuck... Click here to teach me more about this clue!

'circuit material' is the definition.
'semiconductor' can be an answer for 'circuit' (thesaurus). I am unsure of the 'material' bit.

'comedic turn so dreadful' is the wordplay.
'dreadful' indicates anagramming the letters.
'comedic'+'turn'+'so'='comedicturnso'
'comedicturnso' anagrammed gives 'SEMICONDUCTOR'.

'making' is the link.

Can you help me to learn more?

(Other definitions for semiconductor that I've seen before include "No CID customer (anag.)" , "IT board member" , "Material such as silicon" , "Electronic material" , "transistor?" .)

I've seen this clue in The Telegraph.
