Although copper damascene interconnects offer many advantages over conventional subtractive etched Al alloys, the challenges and costs associated with converting to copper have combined to extend the useful life of Al alloy etching into the deep subm

The main types of gate oxide damage measurement techniques are examined and compared, leading to a selection of “application-specific” damage measurement techniques. Each technique has strengths and weaknesses, so no single measurement can comple

The variation of metal etch rate with spacing between metal lines was measured from scanning electron microscopy micrographs of TiN/Al–0.5%Cu/TiN wafers etched in a high density inductively coupled plasma metal etcher. The metal etch rate was found

Antenna structures are commonly used to study charging, and the resultant metal–oxide–semiconductor gate oxide damage, from plasma processing. Degradation of various device parameters, such as gate leakage and threshold voltage, have been correla

Gate oxide damage resulting from high density plasma chemical vapor deposition of silicon oxide was investigated using damage sensitive antenna structures with area ratios up to 200,000 :1. Significant damage was detected from an unoptimized oxide de

Charge buildup damage to gate oxide during lightly doped drain (LDD) spacer oxide etch was studied by measuring gate leakage of fully processed transistors over thin oxide attached to area‐intensive or edge‐intensive polycide antenna structures o

Amorphous silicon has been used as a programmable material for a metal-to-metal anti-fuse. A study on the characteristics of such an anti-fuse and the parameters that affect its programming characteristics is presented. In the unprogrammed state the

A programmable anti-fuse, using amorphous silicon between levels of metal, is studied. The step coverage of the a-Si has the most significant impact on the anti-fuse characteristics. Other critical process parameters are also identified. The anti-fus
