The “More than Moore” semiconductor industry is

changing the transportation paradigm

ve r t he pa s t one a nd a

half centuries automobile

t e c h n o l o g y h a s

revolutionized many indust r ies and

impacted the evolution and creation of

new trends in our daily lives. Today,

another revolution is in progress in the

automotive world, with a race for “More

t han Moore” semiconduct or s, t hat

started just a few decades ago.

W h a t ’s b e e n h a p p e n i n g w i t h

a u t omob i l e s ove r t h e ye a r s? T h e

semiconductor industry has started to

flood cars with electronic injection chips,

par tly in response to environmental

ef f iciency requ i rement s. Th is wa s

followed by security features, which

have been the biggest driver ever since,

with the addition of anti-lock brake

systems (ABS), elect ronic stabilit y

control (ESC), tire pressure monitoring

systems (TPMS), etc. The new trend for

electrification has given a new thrust to

the automotive semiconductor market

by trying to solve the environmental

issue for good. The advent of digital

connectivit y with smar t phones has

given rise to new business models and a

different approach to the transportation

paradigm, with its opportunities for

shared mobility (

Figure 1

). This leads

us to the fashionable autonomous car,

which is seen as the Holy Grail of the

automotive market, but the situation is

considerably more complex than was

first thought. Two major automotive

trends are evolving in parallel.

F i r s t , au t oma t e d c a r s “a s we

know them.”

Based on our traditional

automobile, these vehicles will evolve

through different stages of automation,

from level 1 to level 5, through the

add it ion of pre - embedded sensors,

i nclud i ng rada rs and cameras, and

new ones such as light detection and

rang i ng systems (LiDARs), helped

by powerful computing capacity that

will solve problems and ensu re the

car reacts effectively to any situations

occurring on the roads. These features,

known as advanced driver assistance

s y s t e m s (A DAS ) , a r e c u r r e n t l y

focusing all the attention of original

equipment manufacturers (OEMs) and

tier one suppliers.

Second, there are “robotic cars.”

Based on a robotic approach, these cars

are being developed by Google, Uber,

Lyft, and Baidu and will address new

types of use. Born as a level 4, or even 5,

these “sensitive” robots are created with

one objective: to fulfill the autonomous

driving (AD) requirements of being able

to drive everywhere, as a new type of

personal transportation. These vehicles

are expected to become fully operational

in restricted areas before evolving to

a true level 5 (

Figure 2

). Autonomous

driving is arguably the most exciting

development in the industry today and

the future of the automotive industry is

clearly to address these new challenges.

“More than Moore” semiconductors

for sensing

Le t ’s t a ke a look a t t he cu r r ent

battlefront. A majority of automotive

i n d u s t r y p l a y e r s a r e c u r r e n t l y

developing sensor-based solutions to

increase vehicle safety in high and low

speed zones. These ADAS systems

use a combination of advanced sensors

combi ne d w it h a c t u a t o r s , cont r ol

units and integrating software. They

enable the driver and car to monitor

and respond to the surroundings. Some

ADAS features are already available.

These include land keeping assist (LKA)

and lane keepi ng wa r n i ng (LKW),

adaptive cruise control, back-up alerts

and parking assistance. Many others are

still under development. To reach the

fully-automated level, advanced sensors

combined with actuators, control units

and integrating software will have to be

fully mastered. Sensing, computing and

actuating are the three major blocks at

the heart of this revolution. Let us focus

on the first two, as automotive players

have already mastered the last one.

For many years, the semiconductor

i ndust r y ha s been focusi ng on t he

“Moore approach.” The advent of the

“More than Moore” semiconductor

industry has led us to the sensing era

and the proliferation of sensors in the
