Metal lines are provided covered by an insulating layer overlying a semiconductor substrate. A first dielectric layer of a first type is deposited overlying the insulating layer. A second dielectric layer of a second type is deposited overlying the first dielectric layer. A via pattern is etched into the second dielectric layer.

    摘要: A transient protection circuit is described which provides electrostatic discharge (ESD) protection for an internal circuit of an IC. The transient protection circuit comprises two Zener diodes connected in series between the input pad and the internal circuit of the IC. A sufficiently large ESD pulse will drive one the two Zener diodes into breakdown mode, thereby reducing the magnitude of the ESD pulse to the remainder of the circuit. Resistive means are paralleled with the Zener diodes to provide a signal path at non-ESD voltages. To help shunt the ESD current away from the internal circuit, PMOS and NMOS transistors are connected in parallel between the positive and the negative voltage supply and their junction is connected to the internal circuit. Negative ESD pulses cause the PMOS transistors to turn on, dumping the ESD energy into the positive voltage supply, while positive ESD pulses cause the NMOS transistors to turn on, dumping the ESD energy into the negative voltage supply. Voltage changes, caused by currents flowing through the resistive means, trigger parasitic SCRs into conduction to provide the bulk of the ESD protection.

    摘要: A method of fabricating a transistor, comprising the following steps. A silicon semiconductor structure having spaced, raised, wedge-shaped dielectric isolation regions defining an active region there between is provided. Epitaxial silicon is grown over the active area to form an SEG region. A dummy gate is formed over the SEG region. Raised epitaxial silicon layers are grown over the SEG region adjacent the dummy gate. The dummy gate is removed, exposing the interior side walls of the raised epitaxial silicon layers. Sidewall spacers are formed on the exposed sidewalls of the raised epitaxial silicon layers. A gate oxide layer is grown over the SEG region and between the sidewall spacers of the raised epitaxial silicon layers. A layer of polysilicon is deposited over the structure and is planarized to form a gate conductor over the SEG region and between the sidewall spacers of the raised epitaxial silicon layers. The sidewall spacers are removed. No HDP process trench fill is required to form the STIs and no CMP process is required to planarized the STIs.

    摘要: A method of forming thick and thin gate oxides comprising the following steps. A silicon semiconductor substrate having first and second active areas separated by shallow isolation trench regions is provided. Oxide growth is selectively formed over the first active area by UV oxidation to form a first gate oxide layer having a first predetermined thickness. The first and second active areas are then simultaneously oxidized whereby the first predetermined thickness of the first gate oxide layer is increased to a second predetermined thickness and a second gate oxide layer having a predetermined thickness is formed in the second active area. The second predetermined thickness of the first oxide layer in the first active area is greater than the predetermined thickness of the second oxide layer in the second active area.

    摘要: A new method for forming a silicon-on-insulator MOSFET while eliminating floating body effects is described. A silicon-on-insulator substrate is provided comprising a silicon semiconductor substrate underlying an oxide layer underlying a silicon layer. A first trench is etched partially through the silicon layer and not to the underlying oxide layer. Second trenches are etched fully through the silicon layer to the underlying oxide layer wherein the second trenches separate active areas of the semiconductor substrate and wherein one of the first trenches lies within each of the active areas. The first and second trenches are filled with an insulating layer. Gate electrodes and associated source and drain regions are formed in and on the silicon layer in each active area. An interlevel dielectric layer is deposited overlying the gate electrodes. First contacts are opened through the interlevel dielectric layer to the underlying source and drain regions. A second contact opening is made through the interlevel dielectric layer in each of the active regions wherein the second contact opening contacts both the first trench and one of the second trenches. The first and second contact openings are filled with a conducting layer to complete formation of a silicon-on-insulator device in the fabrication of integrated circuits.

    摘要: A new method of fabricating a rim phase shifting mask is achieved. An opaque layer is provided overlying a transparent substrate. A resist layer is deposited overlying the opaque layer. The resist layer is patterned. The opaque layer and the transparent substrate are etched. The resist layer masks this etching. The opaque layer is etched through during this etching. Notches are thereby etched into the transparent substrate at the edges of the opaque layer. These notches will cause a phase shift in incident light relative to incident light passing through regions in the transparent substrate adjacent to the notches. During this etching, an overetch is performed to remove any mask defects in the transparent substrate. Optionally, the notches may be etched into a phase shifting layer overlying the transparent substrate. An etch stopping layer may also be used in the phase shifting layer embodiment.
