摘要： A method of forming a direct, copper-to-copper, connection between levels in an IC is disclosed. A via interconnection is formed by isotropically depositing a barrier material in a via through an insulator to a lower copper level, and then anisotropically etching the via to remove the barrier material covering the lower copper level. The anisotropic etch leaves the barrier material lining the via through the insulator. The subsequently deposited upper metal level then directly contacts the lower copper level when the via is filled. A dual damascene interconnection is formed by etching an interconnection trench in an insulator and anisotropically depositing a non-conductive barrier material in the trench bottom. Then a via is formed from the trench interconnect to a lower copper level. As above, a conductive barrier material is isotropically deposited in the trench/via structure, and anisotropically etched to remove the barrier material covering the lower copper level. The insulating barrier material, lining the trench and via, remains. An IC via interconnection structure and a dual damascene interconnection structure, made in accordance with the above described methods, are also provided.

摘要： A method of forming a MOS transistor without a lightly doped drain (LDD) region between the channel region and drain is provided. The channel region is formed from a tilted ion implantation after the deposition of the gate oxide layer. The tilted implantation forms a relatively short channel length, with respect to the length of the gate electrode. The position of the channel is offset, and directly adjoins the source. The non-channel area under the gate, adjacent the drain, replaces the LDD region between the channel and the drain. This drain extension acts to more evenly distribute electric fields so that large breakdown voltages are possible. The small channel length, and eliminated LDD region adjacent the source, act to reduce resistance between the source and drain. In this manner, larger I.sub.d currents and faster switching speeds are obtained. A MOS transistor having a short, offset channel and drain extension is also provided.
摘要翻译：提供了一种形成在沟道区和漏极之间没有轻掺杂漏极（LDD）区的MOS晶体管的方法。沟道区域是在淀积栅极氧化物层之后由倾斜的离子注入形成的。相对于栅电极的长度，倾斜注入形成相对短的沟道长度。通道的位置偏移，并直接与源相邻。在漏极附近的栅极下方的非沟道区域替代通道和漏极之间的LDD区域。这种漏极扩展用于更均匀地分布电场，使得可以实现大的击穿电压。较小的通道长度和消除与源极相邻的LDD区域起到降低源极和漏极之间的电阻的作用。以这种方式，获得更大的Id电流和更快的开关速度。还提供了具有短的偏置沟道和漏极延伸的MOS晶体管。

摘要： A method is provided for forming a metal/semiconductor/metal (MSM) back-to-back Schottky diode from a silicon (Si) semiconductor. The method deposits a Si semiconductor layer between a bottom electrode and a top electrode, and forms a MSM diode having a threshold voltage, breakdown voltage, and on/off current ratio. The method is able to modify the threshold voltage, breakdown voltage, and on/off current ratio of the MSM diode in response to controlling the Si semiconductor layer thickness. Generally, both the threshold and breakdown voltage are increased in response to increasing the Si thickness. With respect to the on/off current ratio, there is an optimal thickness. The method is able to form an amorphous Si (a-Si) and polycrystalline Si (polySi) semiconductor layer using either chemical vapor deposition (CVD) or DC sputtering. The Si semiconductor can be doped with a Group V donor material, which decreases the threshold voltage and increases the breakdown voltage.

摘要： An array of fully isolated multi-junction complimentary metal-oxide-semiconductor (CMOS) filterless color imager cells is provided, together with an associated fabrication method. The method provides a bulk silicon (Si) substrate. A plurality of color imager cells are formed, either in the Si substrate, or in a single epitaxial Si layer formed over the substrate. Each color imager cell includes a photodiode set with a first, second, and third photodiode formed as a stacked multi-junction structure. A U-shaped (in cross-section) well liner, fully isolates the photodiode set from adjacent photodiode sets in the array. For example, each photodiode is formed from a p doped Si layer physically interfaced to a first wall. A well bottom physically interfaces to the first wall, and the p doped Si layer of the third, bottom-most, photodiode is part of the well bottom. Then, the photodiode sets may be formed from an n/p/n/p/n/p or n/p/p−/p/p−/p layered structure.

摘要： A method is provided for forming a rare earth element-doped silicon oxide (SiO2) precursor with nanocrystalline (nc) Si particles. In one aspect the method comprises: mixing Si particles into a first organic solvent, forming a first solution with a first boiling point; filtering the first solution to remove large Si particles; mixing a second organic solvent having a second boiling point, higher than the first boiling point, to the filtered first solution; and, fractionally distilling, forming a second solution of nc Si particles. The Si particles are formed by immersing a Si wafer into a third solution including hydrofluoric (HF) acid and alcohol, applying an electric bias, and forming a porous Si layer overlying the Si wafer. Then, the Si particles are mixed into the organic solvent by depositing the Si wafer into the first organic solvent, and ultrasonically removing the porous Si layer from the Si wafer.
