    摘要: A semiconductor structure provided with a plurality of gated-diodes having a silicided anode (p-doped region) and cathode (n-doped region) and a high-K gate stack made of non-silicided gate material, the gated-diodes being adjacent to FETs, each of which having a silicided source, a silicided drain and a silicided HiK gate stack. The semiconductor structure eliminates a cap removal RIE in a gate first High-K metal gate flow from the region of the gated-diode. The lack of silicide and the presence of a nitride barrier on the gate of the diode are preferably made during the gate first process flow. The absence of the cap removal RIE is beneficial in that diffusions of the diode are not subjected to the cap removal RIE, which avoids damage and allows retaining its highly ideal junction characteristics.

    摘要: A method and apparatus for identifying defective partially manufactured semiconductor wafers in a manufacturing line is described, wherein defects caused by silicon erosion created by over-etching the wafer can be detected. The method described herein is based on an in-line test of selected structures, such as FETs, located in the kerfs that surround the integrated circuit chips. Leakage current between the gate and the source-drain region is measured at FETs in each kerf. Based on the measurement, a leakage current map is created and compared to a standard map. In accordance with this comparison and to the distribution of patterns of leakage currents, it is determined whether or not the wafer is defective. This determination is performed in the kerfs after formation of the gate and source-drain regions, and prior to the wafer being completed. By detecting defective wafers at an early stage, considerable manufacturing resources are saved.

    摘要: Disclosed are embodiments of a self-protected electrostatic discharge field effect transistor (SPESDFET). In the SPESDFET embodiments, a resistance region is positioned laterally between two discrete sections of a deep source/drain region: a first section that is adjacent to the channel region and a second section that is contacted. The second section of the deep source/drain region is silicided, but the first section adjacent to the channel region and the resistance region are non-silicided. Additionally, the gate structure can be either silicided or non-silicided. With such a configuration, the disclosed SPESDFET provides robust ESD protection without consuming additional area and without altering the basic FET design (e.g., without increasing the distance between the deep source/drain regions and the channel region). Also disclosed are embodiments of integrated circuit that incorporates the SPESDFET as an input/output (I/O) pad driver and method embodiments for forming the SPESDFET and the integrated circuit.
