    • A semiconductor chip comprises low voltage complementary metal oxide semiconductor (CMOS) sectors and high voltage lateral double diffused metal oxide semiconductor (LDMOS) sectors and at least one transistor within at least one of the low voltage CMOS sectors. The transistor has a semiconducting channel region within a substrate. A gate conductor is above the top layer of substrate, and the gate conductor is positioned above the channel region. A source/drain region is included in the substrate on a first side of the gate conductor and a lateral source/drain region is included in the substrate on a second side of the gate conductor opposite the first side. The lateral source/drain region is positioned a greater distance from the gate conductor than the source/drain region is positioned from the gate conductor. The embodiments herein also include a source/drain ballast resistor in the substrate between the lateral source/drain region and the gate conductor.

    • A structure for improving the electrostatic discharge robustness of an integrated circuit having an electrostatic discharge (ESD) device and a receiver network connected to a pad by interconnects. The interconnect between the pad and the ESD device has a high-k material placed adjacent to at least one surface of the interconnect and extending over the thermal diffusion distance of the interconnect. The high-k material improves the critical current density of the interconnect by increasing the heat capacity and thermal conductivity of the interconnect. The high-k material can be placed on the sides, top and/or bottom of the interconnect. In multiple wire interconnects, the high-k material is placed between the wires of the interconnect. A low-k material is placed beyond the high-k material to reduce the capacitance of the interconnect. The combination of low-k and high-k materials provides an interconnect structure with improved ESD robustness and low capacitance that is well suited for an ESD device. The interconnect to the receiver, which does not carry a high current, is surrounded by a low-k material for reduced capacitance and performance advantages.

    • Disclosed is a triple well CMOS device structure that addresses the issue of latchup by adding an n+ buried layer not only beneath the p-well to isolate the p-well from the p− substrate but also beneath the n-well. The structure eliminates the spacing issues between the n-well and n+ buried layer by extending the n+ buried layer below the entire device. The structure also addresses the issue of threshold voltage scattering by providing a p+ buried layer below the entire device under the n+ buried layer or below the p-well side of the device only either under or above the n+ buried layer) Latchup robustness can further be improved by incorporating into the device an isolation structure that eliminates lateral pnp, npn, or pnpn devices and/or a sub-collector region between the n+ buried layer and the n-well.

    • An ESD network. The ESD network including a redundant voltage clamping element in series with a first voltage clamping element between two voltage pads. The ESD network may be connected to a power voltage pad or a signal voltage pad either directly or through a dummy voltage pad. The voltage clamping elements may further comprise an array of unit cells wherein the array is electrically equivalent to single large transistors currently used in ESD networks. By creating an ESD network as an array of unit cells, benefits greater than those obtained by using a single transistor as a clamping or a trigger element are realized such as increased ballast resistance and less overall damage to the circuitry resulting from cosmic rays and particles.
    • 一个ESD网络。 ESD网络包括与两个电压焊盘之间的第一电压钳位元件串联的冗余电压钳位元件。 ESD网络可以直接或通过虚拟电压焊盘连接到电源电压焊盘或信号电压焊盘。 电压钳位元件还可以包括单元电池阵列,其中阵列电气上等同于目前在ESD网络中使用的单个大型晶体管。 通过将ESD网络创建为单元单元阵列,实现比通过使用单个晶体管作为钳位或触发元件获得的优点更大的益处,例如增加的镇流电阻和对由宇宙射线和粒子产生的电路的总体损坏。
