No, I do not think so.
When we design a device, what appear in our mind is energy band diagram, not
equations. Without a physical picture in mind, how can one understand how
the device works.
What more important is that for new designs,( I do not mean those conventional
structure, such as basic MOS, BJT), there is no equation or math  available
to describe them. Since even a small variation from the basic structure, it
will make the math much more complicated. No device guy would like to work
with device physicist to work out the equations. They just keep  the physical
model in their mind and first fabricate the device out. They will test the
idea by experiments.  This is the way how device guy works at least here.

【 在 tamubird (tamubird) 的大作中提到: 】
: I don't think so. Frankly, I think everything is mathematics.
: The mathematics in device or analog is just a little bit more
: complex. Analog will seem obscure if you are not good at
: complex mathematics.
: Surely I don't mean I need know nothing about device. I mean
: not too much. I learn some device physics before. But after
: design for many years, the device physics is more and more
: obscure while the equations are clearer and clearer.
: Most EE students are poor at mathematics. That's a tragedy.
: Including me. hehe.
: 【 在 photonwave (laser) 的大作中提到: 】
: : Stupid thought!
: : 要是以后定位在只作DESIGN,DEVICE中的那些东西对DESIGN有用吗?DESIGN只需要MODEL
: : 教材
