Even a brief perusal of a grep at google will tell you as much.

You just babbling because you are lonely or something?

There is processing, of course, but the question is whether it changes
the Raw sensor data. But ....

First, of course, there has to be processing even to obtain what we
think of as the Raw sensor data. Sensors deliver electrons, and cameras
do not just store a count of electrons into the Raw file. So they must
have an algorithm for converting the count of electrons, or amount of
charge, into the numbers held in the Raw file or used for further
processing.

Second, I have seen a suggestion that the Nikon D70 does further
processing in order to compress the sensor data further. I think this
is the only case of lossy compression of sensor data I've read about,
and I have no independent evidence for this statement:

"The Compressed NEF format is the only one that comes close to
retaining the full data set the D70 is capable of acquiring. I say
"close to retaining" because the compression scheme Nikon uses is not
lossless. Basically, the camera takes the highlight data and places
them into groups (essentially a rounding of many of the data points),
producing the equivalent to somewhere between 9 and 10 bits of data.
When this is returned to 12-bit form, there's a bit of posterization in
the highlight data. The reason this works as a visually lossless scheme
is that our eyes really can't resolve more than about an 8-bit value
can produce (and our eyes aren't linear in response to light, either).
For the most part it isn't a big thing that the compression loses data,
though there may be some post-processing manipulations that will render
slightly differently because of the data rounding."

Third, generating the file itself is not really an issue. A Raw file is
a container, and generating the tags or whatever of the container
doesn't itself mean that the sensor data is being changed.

None of the above is about any type of processing that uses data from
more than one pixel (or "sensel"?) at a time. (Sharpening, noise
reduction, etc). I think that is what people are normally talking about
when they distinguish between Raw and other formats.

So what? Each cell is doing the subtraction from it's own ambient noise
level to get the signal value. How do you see this as an image
enhancement? [I assume your refer processing as noise
reduction/enhancement.] And do you know how much is the noise floor
level of your CCD? How about the noise generated by the amplifier used
to capture the signal from the CCD? If you don't like CMOS, then don't
dream of D2X.
