What is the IDM revenue exposure right now
tually will like to see that. So I think the macro trend is very clear.
But in terms of, how do we take one step to another, the reality is very complicated. You will really have to have a foundry development, you have to have the architectural development, material process, the mechanical, thermal, and all of the things will take a unique company to put a lot of R&D resource to make sure they can define the standard for that. And I think that's what we're seeing today. The good thing is packaging is emerging as a more critical integral part for the whole semiconductor ecosystem. And that's welcome. But in terms which technology will be more industrial lies pervasive. And I think the time would prove that but ASE will not be missing this part.

Next question?
Operator
Next question is from Mr. Bruce Lu of Goldman Sachs. Bruce?
Bruce Lu -- Goldman Sachs -- Analyst
Okay. I want to have a quick follow up for the CapEx. What's the CapEx allocation for testing, bonding, wire bonding for this year?
Ken Hsiang -- Head of Investor Relations
The CapEx location or allocation.
Bruce Lu -- Goldman Sachs -- Analyst
Allocation?
Ken Hsiang -- Head of Investor Relations
Okay. So you're asking about basically cap, planned CapEx for test?
Bruce Lu -- Goldman Sachs -- Analyst
For everything, I mean, you know, what's the CapEx allocation? Yes.
Joseph Tung -- Chief Financial Officer
I think for this year, the likely allocation will be around 65% for assembly, roughly 23% to 25% for tests, a little bit for material and then roughly 9% to 10% for EMS.
Bruce Lu -- Goldman Sachs -- Analyst
Okay. So assuming that your equipment lead time right now is more than a year, so your CapEx for next year should be foreseeable?
Joseph Tung -- Chief Financial Officer
Ah?
Bruce Lu -- Goldman Sachs -- Analyst
Because you already mentioned that the CapEx, the equipment lead time right now is more than a year, right?
Joseph Tung -- Chief Financial Officer
Yes.
Bruce Lu -- Goldman Sachs -- Analyst
So basically you know how many equipment you're going to spend for the coming like 12/15 months already. So which means that your CapEx for next year should have a very clear pictures.
Joseph Tung -- Chief Financial Officer
Well, when we talked about CapEx, we're talking about required CapEx. It's not necessarily the test CapEx that we're talking about.
Bruce Lu -- Goldman Sachs -- Analyst
Oh, I see. Okay. Oh, then the next question is a good question. Can you give us the revenue contributing from automotive or from the IDM in your ATM business?
Ken Hsiang -- Head of Investor Relations
Bruce, so you're looking for how much revenue the automotive sector represents?
Bruce Lu -- Goldman Sachs -- Analyst
Yes, in ATM.
Joseph Tung -- Chief Financial Officer
Oh, roughly, the second quarter is around 6%, 5% to 6%.
Bruce Lu -- Goldman Sachs -- Analyst
Do you see a clear uptrend?
Joseph Tung -- Chief Financial Officer
Yeah. Well, I think we're pretty aggressive in terms of programming of our auto business.
Bruce Lu -- Goldman Sachs -- Analyst
Do you expect it to be more than 10% in 2022?
Joseph Tung -- Chief Financial Officer
Well, we'll look at it. But it's actually -- it's going to be quite a bit of growth this year, over 50% type growth.
Bruce Lu -- Goldman Sachs -- Analyst
Wow! Okay. So what is the IDM revenue exposure right now?
Joseph Tung -- Chief Financial Officer
The IDM exposure?
Bruce Lu -- Goldman Sachs -- Analyst
Yes, IDM customers.
Joseph Tung -- Chief Financial Officer
Yeah. Around 1/3 of all this is coming from IDM.
Bruce Lu -- Goldman Sachs -- Analyst
I see, I understand. Thank you.
Ken Hsiang -- Head of Investor Relations
Do we have additional questions at this time?
Operator
There is no question.
Ken Hsiang -- Head of Investor Relations
Okay. I'll turn it over to Dr. Tien Wu to wrap up the call.
Tien Wu -- Chief Operating Officer
