    摘要: 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.

    摘要: A design structure for electrostatic discharge protection comprises a first data representing a first electrostatic discharge (ESD) protection circuit and a second data representing a second ESD protection circuit. A parallel connection of two ESD protection units, each providing a discharge path for electrical charges of opposite types, provides ESD protection circuit for positive and negative voltage swings in the circuit. Each of the multiple emitter-base regions are cascoded such that the base of one emitter-base region is directly wired to the emitter of an adjacent emitter-base region. The first data represents a first ESD protection unit providing protection on one type of voltage swing, and the second data represents a second ESD protection unit providing protection on the other type of voltage swing.

    摘要: A P-N junction device and method of forming the same are disclosed. The P-N junction device may include a P-N diode, a PiN diode or a thyristor. The P-N junction device may have a monocrystalline or polycrystalline raised anode. In one embodiment, the P-N junction device results in a raised polycrystalline silicon germanium (SiGe) anode. In another embodiment, the P-N junction device includes a first terminal (anode) including a conductor layer positioned above an upper surface of a substrate and a remaining structure positioned in the substrate, the first terminal positioned over an opening in an isolation region; and a second terminal (cathode contact) positioned over the opening in the isolation region adjacent the first terminal. This latter embodiment reduces parasitic resistance and capacitance, and decreases the required size of a cathode implant area since the cathode contact is within the same STI opening as the anode.

    摘要: A structure, apparatus and method for circuits to minimize sensitivity to latch. The method includes, for example, identifying element density of at least one functional circuit block and element attributes of elements associated with the at least one functional circuit block. An element density function parameterized from the element attributes is formed. The placement of the at least one functional circuit block is modified relative to other functional circuit blocks based on the element density function to substantially eliminate latching effects in a circuit.

    摘要: Realizing that rather than protect electronic circuitry, electrostatic discharge networks when hit by cosmic rays and charged particles, can actually cause the electronic circuitry in satellites and other space applications to fail, the inventor created an ESD network having 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.
