The ion beam can also be used to deposit a metal, such as platinum, to create new connections. These techniques are very useful tools for debugging designs and testing possible changes to the circuit without the expense of new mask sets or silicon. This paper presents test structures to characterise a FIB platinum deposition process. Sheet resistance test structures have been fabricated using a FIB tool and the results of testing these structures are presented. This data will enable resistors with a known value to be fabricated in addition to conducting straps.","PeriodicalId":188074,"journal":{"name":"Proceedings of the 2002 International Conference on Microelectronic Test Structures, 2002.

In particular, it highlights the strong decrease of MOSFET matching performance when the device area is reduced, by comparison to the fluctuations at the wafer level. This amazing tendency involves that the well-known phenomenon responsible for the MOS transistor mismatch do not dominate for the smallest devices. In particular, the impact of polysilicon edge roughness induced by stochastic process during photolithography or etching is investigated.","PeriodicalId":188074,"journal":{"name":"Proceedings of the 2002 International Conference on Microelectronic Test Structures, 2002.

First, a new approach to modeling non-uniform vertical doping profiles in MOSFETs is presented, based on non-linear mapping of the backgate bias. Second, a technique that guarantees that limiting of V/sub ds/ at saturation will not lead to glitches in output conductance is presented. Finally, requirements for limiting functions for V/sub ds/ that do not cause discontinuities in high order derivatives at V/sub ds/ = 0 are defined. Examples of limiting functions that maintain proper symmetry are given. The techniques to eliminate glitches in output conductance and maintain symmetry are applicable to MOSFET and resistor models.","PeriodicalId":188074,"journal":{"name":"Proceedings of the 2002 International Conference on Microelectronic Test Structures, 2002.

Each of these steps will have more or less variation, which has to be within a,certain limit to guarantee the chips functionality at a target speed. But, not every chip layout is susceptive to process variation the same way, which requires a link between process,capabilities and product design. This paper will present a novel Logic Characterization Vehicle (LCV) to investigate the yield and performance impact of process variation on high volume product chips. The LCV combines and manipulates new or already documented circuits like memory cells and combinatorial logic circuits within a JIG interface that allows fast and easy testability. Beside the functionality of such circuits, also path delay as well as cross talk issues can be determined. A standard digital functional tester can be used, since all timing critical measurements will be performed within the JIG. The described method allows early implementation of existing circuits for future technology nodes (shrinks). A Design Of Experiments (DOE) based implementation of possible layout manipulations will determine their impact on yield and performance of a target design as well as its sensitivity to process variation. The described approach can be used at a much earlier stage of product and process development, which will significantly shorten yield ramp.","PeriodicalId":188074,"journal":{"name":"Proceedings of the 2002 International Conference on Microelectronic Test Structures, 2002.

A high quality tunnel oxide will result in good cell endurance characteristics. However, the conventional tunnel oxide characterization is usually based on a large area capacitor test structure with a high sheet resistance floating poly-silicon gate, and, as a result, an over-estimated oxide quality is obtained. In this study, we design a new test structure and a new characterization methodology for tunnel oxide measurement. It is found that more accurate and reliable tunnel oxide lifetime prediction can be obtained with this new approach. Besides, this measurement is correlated to flash memory endurance performance.","PeriodicalId":188074,"journal":{"name":"Proceedings of the 2002 International Conference on Microelectronic Test Structures, 2002.
