Embodiment Construction

[0085] A novel set of structures and methods are provided to reduce power consumption in large arrays of electronic devices and systems. Some of these structures and methods can be implemented in large numbers by reusing existing bulk CMOS process flows and fabrication techniques, allowing the semiconductor industry, and the electronics industry more broadly, to avoid costly and risky switches to alternative technologies.

[0086]As noted above, some structures and methods involve deep depletion channel (DDC) designs. DDC can allow CMOS devices with reduced σV compared to traditional bulk CMOS T , and can allow the threshold voltage V of the FET with dopants in the channel region T is set much more precisely. DDC designs can also have a stronger body effect than conventional bulk CMOS transistors, which can allow significant dynamic control of power dissipation in DDC transistors. There are many ways to structure a DDC to achieve different advantages, and the additional fea...

Abstract

A suite of novel structures and methods is provided to reduce power consumption in a wide array of electronic devices and systems Some structures and methods can be implemented largely by reusing existing bulk CMOS process flows and manufacturing technology, allowing the semiconductor industry as well as the broader electronics industry to avoid a costly and nsky switch to alternative technologies Some structures and methods relate to a Deeply Depleted Channel (DDC) design, allowing CMOS based devices to have a reduced oVT compared to conventional bulk CMOS and can allow the threshold voltage VT ofFETs having dopants in the channel region to be set more precisely The DDC design also can have a strong body effect compared to conventional bulk CMOS transistors, which can allow for significant dynamic control of power consumption in DDC transistors There are many ways to configure the DDC to achieve different benefits.
