Popis: The influence of proximity correction on device yield and process latitude in electron-beam fabrication of short-period metal-semiconductor-metal (MSM) photodetectors is investigated. A modified Fourier-transform deconvolution method is used for proximity correction. Scattering data is obtained from Monte Carlo simulation, without the need for costly experimental parameter determination. Proximity correction leads to a significant improvement in device yield and process latitude. Figures of merit for latitude enhancement typically are in the range 2…10, depending on device geometry and process context. For a field-effect transistor compatible process technology, MSM devices with finger periods down to 200 nm can be realized using proximity corrected exposure.
