`Kawagoe has a graded dopant concentration to aid carrier movement
`
`“Thus, the impurity concentration of the
`p-well 6p is given such a gradient that it
`is gradually lowered in the depthwise
`direction from the surface of the epitaxial
`layer 2E, so that the influence to be
`caused by the carriers (or electrons) due
`to the (cid:303)-ray is lowered. Specifically, the
`electrons produced by the (cid:303)-ray are
`attracted to the substrate body 2S by
`that
`concentration gradient and
`prevented from entering the p-well 6p
`so that the soft errors can be reduced in
`case the MIS memory of the DRAM or
`the like is formed in the p-well 6p.”

`Q. And how does the -- how does a
`graded dopant concentration relate to
`the idea of carrier drift?
`A. There's really two things that go on,
`but one is the gradient of a charge
`causes electrical -- electrical
`field…The gradient is just the first
`derivative. It's a differential operator.
`So it's the slope, literally. So the slope
`of the charge densities are
`proportional to the field that's
`given off. So this charge gradient
`produces a field which will act upon
`other charge particles.

`
`No dispute that electric fields “provide a force … aiding
`movement in the direction of the force”
`Q. And you relied on that logic, […] if slope is downward, then carriers
`will move; is that basically the logic that you applied? […]
`A. No. As I've said, if [...] you have a downward-sloping graded
`dopant concentration, we know from the basic physics that that will
`lead to an electric field and that will create a force, which tends to
`move the carriers.
`Q. So when you talk about in paragraph 49 a concentration gradient
`aiding carrier movement or impeding carrier movement, that cannot
`be agnostic to the direction of the carrier movement, right?
`A. Well, a field will provide a force in a direction aiding -- direction --
`aiding movement in the direction of the force. That's just basic
`physics.

`Greenthread’s flawed arguments about “aid carrier movement”
`
`What Greenthread says:
`“Graded” does not mean “aided”
`
`•
`
`• Direction of slope insufficient to show “aided”
`
`Why this argument fails:
`
`• Petitioner has shown that specific gradients in Petitioner has shown that specific grad
`prior art would aid carrier movement
`
`• The patents do not disclose any required slope The patents d
`
`magnitude
`
`• External hypothetical forces may overcome
`internal electric field from gradient
`
`• The prior art does not have such external The prio
`
`forces
`
`• Kawagoe does not address carriers in the
`active region
`
`• The same electric field in Kawagoe extends The same electric field in Kawag
`
`through active region and well

`gradient that is high at the emitter-base junction and
`low at the base-collector injunction. This corresponds

`‘relative slope’ which means nothing more than
`the fact that one-side is relatively lower than the

`help the holes (p-n-p transistor) traverse from the
`emitter to collector.”

`Example dopant concentrations for emitter-collector gradient
`are irrelevant
`
`“The relative doping concentrations of emitter
`and collector
`regions varies from 1018 to
`1020/cm3, whereas the base region is 1014 to
`1016/cm3
`depending
`on
`the

`characteristics of the BJT. In graded base p-n-p
`transistors, the donor dopant concentration may
`be 10 to 100x at the emitter-base junction,
`relative to the base-collector junction 60 (1x). The
`gradient can be linear, quasi linear, exponential
`or complimentary error function. The relative
