    摘要: The reliability of an antifuse can be increased and/or the thickness of the antifuse dielectric can be decreased by the use of a rapid thermal nitridation nitride layer as part of the antifuse dielectric. The RTN nitride layer is denser and has fewer pinholes than nitride layers formed by chemical vapor deposition. The rapid thermal nitridation also produces a good contact with a bottom electrode containing silicon as well as providing a nucleation layer for any additional nitride layer formed by chemical vapor deposition. Increasing the reliability of the antifuse dielectric allows it to be thinner, and thus allows for the programming of the dielectric layer at lower programming voltages.

    摘要: A semiconductor substrate having a surface, a field oxide region at the surface and a gate structure above the surface are provided. A sidewall spacer is formed adjacent to the gate structure and a polysilicon layer is formed above the substrate, the polysilicon layer having raised first and second portions above the gate structure and field oxide region, respectively. A masking layer is formed above the polysilicon layer and then blanket etched to expose the raised first and second portions of the polysilicon layer which are subsequently removed to form a raised source/drain region from the polysilicon layer. Since the raised source/drain region is fabricated without using photolithography, high density MOSFETs are readily fabricated.

    摘要: The present invention is directed to a spin chuck for use in a process, such as a cleaning process and an etching process, performed while rotating a substrate. The spin chuck includes a spin head on which a substrate is placed, a driving part configured to rotate the spin head, and a fix bracket installed on the spin head and having a contact surface that is in contact with a flat surface of a flat zone of the substrate at a position corresponding to the flat zone to prevent a vortex caused by the flat zone. Since the fix bracket has the same shape as the flat zone of the substrate, an air current unbalance resulting from the flat zone is suppressed to uniformly inject etchants to a rear surface of the substrate.

    摘要: A static random access memory (SRAM) cell is given increased stability and latch-up immunity by fabricating the PMOS load transistors of the SRAM cell to have a very low drain/source dopant concentration. The drain/source regions of the PMOS load transistors are formed entirely by a P−− blanket implant. The PMOS load transistors are masked during subsequent implant steps, such that the drain/source regions of the PMOS load transistors do not receive additional P-type (or N-type) dopant. The P−− blanket implant results in PMOS load transistors having drain/source regions with dopant concentrations of 1e17 atoms/cm3 or less. The dopant concentration of the drain/source regions of the PMOS load transistors is significantly lower than the dopant concentration of lightly doped drain/source regions in PMOS transistors used in peripheral circuitry.

    摘要: Systems and methods are described for fabricating semiconductor gate oxides of different thicknesses. Two methods for forming gate oxides of different thicknesses in conjunction with local oxidation of silicon (LOCOS) are disclosed. Similarly, two methods for forming gate oxides of different thicknesses in conjunction with shallow trench isolation (STI) are disclosed. Techniques that use two poly-silicon sub-layers of substantially equal thickness and techniques that use two poly-silicon sub-layers of substantially unequal thickness are described for both LOCOS and STI. The systems and methods provide advantages because gate uniformity and quality are improved, the processes and resulting devices are cleaner, and there is less degradation of carrier mobility.

    摘要: A substrate has defined therein one or more active regions. A layer of polysilicon is deposited and patterned to form gates for various CMOS devices. A masking layer is then deposited and selectively etched to leave exposed portions of the substrate. Dopants of a first conductivity type are implanted into the exposed portions of the substrate to form one or more well regions of the first conductivity type. Using this masking layer and the polysilicon gates left exposed thereby as a mask, dopants of a second conductivity type are then implanted into the substrate to form source and drain regions of the second conductivity type in the well regions of the first conductivity type. The masking layer is then removed. In this manner, source and drain regions may be formed using the same masking layer used to define the well within which the source and drain regions lie, thereby reducing both time and expense in the fabrication of CMOS devices.

    摘要: A ternary CAM system includes a main memory cell configured to store complementary data signals D/D#. A first transistor has a source coupled to receive data signal D#, and a gate coupled to receive a compare signal C. A second transistor has a source coupled to receive data signal D, and a gate coupled to receive complementary compare signal C#. A third transistor has a gate coupled to drain regions of the first and second transistors. A mask cell storing a mask value is coupled to the source of the third transistor. A pre-charged match line is coupled to the drain of the third transistor. If compare signals C/C# match data signals D/D#, then the third transistor is turned off, thereby isolating match line and mask cell. If compare signals C/C# don't match data signals D/D#, then the third transistor is turned on, thereby coupling mask cell and match line.
