    摘要: A semiconductor device with an electrostatic discharge (ESD) protection transistor is devised, wherein the ESD protection transistor has halo regions of an opposite conductivity type from the source and drain regions adjacent thereto. In one embodiment, the ESD protection transistor is a thick field oxide (TFO) transistor. In some cases, the halo regions may be provided with an ion implant step without the use of an extra mask. The halo regions permit the ESD protection transistor to have its breakdown voltage adjusted so that it turns on before the device it is protecting is affected by an ESD event. The use of halo regions avoids the increase in device area and adverse effects to the AC performance of the circuit being protected that are disadvantages of prior approaches.

    摘要: An SOI structure (20) includes a semiconductor layer (15) formed on an insulating substrate (12). The semiconductor layer (15) is partitioned into an ESD protection portion (32) and a circuitry portion (34). A portion of the semiconductor layer (15) in the ESD protection portion (32) and a different portion of the semiconductor layer (15) in the circuitry portion (34) are differentially thinned. A device (60) which implements the desired circuit functions of the SOI structure (20) is fabricated in the circuitry portion (34). An ESD protection device (40) is fabricated in the ESD protection portion (32). The thick semiconductor layer (15) in the ESD protection portion (32) serves to distribute the ESD current and heat over a large area, thereby improving the ability of the SOI structure (20) to withstand an ESD event.

    摘要: First circuitry is powered by a first power supply domain and provides a data signal referenced to the first power supply domain. Second circuitry is powered by a second power supply domain that differs from the first power supply domain. The data signal becomes referenced to the second power supply domain by a clocked level shifter that couples the first circuitry to the second circuitry and buffers the data signal from the first power supply domain to the second power supply domain by only using a single supply voltage. The clocked level shifter is clocked by a signal that is used to precharge a first node and a second node of the clocked level shifter until the data signal is valid for at least a setup time period. The first and second nodes are precharged to establish a known state in the clocked level shifter.
