Is USDC backed by USD 1 to 1?

I've been hearing a lot about USDC recently, and I'm trying to understand its underlying mechanism. Could you clarify for me whether USDC is indeed backed by the US dollar in a one-to-one ratio? This is a crucial aspect for me as I'm considering investing in it. I've read some conflicting information on this matter, and I'm hoping you can provide me with a clear and concise answer. I understand that stability is a key factor in cryptocurrency, and if USDC is indeed fully backed by the US dollar, it would certainly give me more confidence in its value. Could you please elaborate on this point?
