A method of forming a frontside contact to a Silicon-On-Insulator (SOI) wafer is described. A connection polysilicon connects a silicon substrate layer to a contact plug. This connection provides a means to ground or bias the bottom substrate of the SOI wafer. Spacers may be added to provide additional doping.

Neutron detection cells and corresponding methods of detecting charged particles that make efficient use of silicon area are set forth. Three types of circuit cells/arrays are described: state latching circuits, glitch generating cells, and charge loss circuits. An array of these cells, used in conjunction with a neutron conversion film, increases the area that is sensitive to a strike by a charged particle over that of an array of SRAM cells. The result is a neutron detection cell that uses less power, costs less, and is more suitable for mass production.
摘要:
A method of forming a body-tie. The method includes forming the body-tie during an STI scheme of an SOI process. During the STI scheme, a first trench is formed. The first trench stops before a buried oxide layer of the SOI substrate. The first trench may determine a height of body tie that is shared between at least two FETs. A second trench may also be formed within the first trench. The second trench stops in the SOI substrate. The second trench defines the location and shape of a body-tie. Once the location and shape of the body-tie are defined, an oxide is deposited above the body-tie. The deposited oxide prevents certain implants from entering the body tie. By preventing these implants, a source and a drain implant may be self-aligned to the source and drain areas without requiring the use of the photoresist mask to shield the body tie regions from the source and drain implant.

Non-planar SOI devices that include an “area-efficient” body tie are disclosed. The device includes a bulk substrate, an insulator layer formed on a surface of the bulk substrate, and a silicon body formed on a surface of the insulator layer. The silicon body preferably includes (i) a non-planar channel connecting a source region and a drain region, and (ii) a body tie that is adjacent to the channel and couples the channel to a voltage potential. The device further includes a gate dielectric formed on the channel and a gate material formed on the gate dielectric.

An output buffer with built-in ESD protection is disclosed. The built-in ESD protection is preferably formed using transistors from the sea-of-transistors or sea-of-gates region of the integrated circuit, which may eliminate the need for dedicated ESD devices, and in particular, dedicated ESD devices that are pre-fabricated into the under-layers in and around the perimeter of the integrated circuit.

A method for digital programmable optimization of a mixed-signal circuit is provided. The method comprises dividing up one or more transistor devices of the mixed-signal circuit into one or more transistor segments, with each transistor segment including a body tie bias terminal. Each body tie bias terminal is coupled to at least one voltage bias, either by placing each body tie bias terminal in signal communication with one or more bias nodes in the mixed-signal circuit, or by placing each body tie bias terminal in signal communication with a non-precision bias voltage source. Each body tie terminal is also arranged to be in signal communication with a separate one of one or more digital programmable storage elements.

A MOS transistor formed in a silicon on insulator structure includes a rectifying connection between a body portion and the gate. The connection decreases the threshold voltage of the transistor in the reverse bias state and limits a difference in voltage between the body and gate in the forward bias state of the rectifying contact.

This disclosure is directed to devices, integrated circuits, and methods for sensing radiation. In one example, a device includes an oscillator, configured to deliver a signal via an output at intervals defined by an oscillation frequency, and a counter, connected to the output of the oscillator and configured to count a number of times the comparator delivers the output signal. The oscillator includes a radiation-sensitive cell that applies a resistance. The resistance of the radiation-sensitive cell is configured to vary in response to incident radiation, wherein the oscillation frequency varies based at least in part on the resistance of the radiation-sensitive cell.
