Fully depleted silicon transistor are much promising for future developments. Xavier Cauchy writes:
To date, transistor scaling has continued in accordance with Moore’s Law down to 32 nm. Engineering challenges, however, are forcing chipmakers to compromise performance and power efficiency in order to reach smaller nodes – unless they switch to new technologies that help better solve these challenges. Today, the semiconductor industry is starting to deploy such new technologies, largely relying on “fully-depleted” transistors for continued scaling and performance gains.
