The peculiar dipping Low-Mass X-ray Binary EXO 0748-676 represents a paradigm for many dipping LMXB phenomena andhas been extensively studied in X-rays (E < 10 keV) by means of many satellites.We propose to perform for the first time an extensive study of its high energy emissionin order to better understand its geometry (presence and extension of anAccretion Disk Corona and of a thermal halo) temporal properties (e.g. neutron star spin periodmeasured at high energies QPOs etc.) and variability (eclipses dips flares thermonuclear bursts etc.). Gotz et al. (2006) reported the results from an INTEGRAL observation of thesource which however was detected at large off-axis angles making detailedstudies difficult.In order to fully exploit the sensitivity of the INTEGRAL instrumentswe propose to observe this source for a total of 2x200 ks (hexagonal dithering) as a primary target.
