    The silicon-tungsten calorimeter LumiCal, located in very forward region of the future detector at the International Linear Collider, is proposed for the precise luminosity measurements based on the Bhabha scattering process. For this purpose, the precise measurement of the scattering polar angles is crucial. A silicon–tungsten sandwich calorimeter with fine–segmented silicon sensors has been designed for this purpose. This paper describes two slightly different designs of silicon sensors for the LumiCal based on available silicon technologies and especially on the possibility of cutting silicon wafers on curved lines.
