    The Soft Gamma-ray Detector (SGD) onboard the ASTRO-H satellite established the concept of a narrow field-of-view semiconductor Compton telescope using silicon and cadmium telluride detectors surrounded by bismuth germanate active shields. Building on this concept, we developed miniSGD, a balloon-borne proof-of-concept system for compact platforms such as scientific balloons and microsatellites. miniSGD employs 0.5-mm-thick double-sided silicon strip detectors as the scatterer and uses newly developed 2-mm-thick cadmium telluride double-sided strip detectors (CdTe-DSDs) as the absorber. These thick CdTe-DSDs were designed to improve detection efficiency while maintaining excellent energy and spatial resolution. The fine 250 μm strip pitch further enhances spatial resolution compared with the 3.2 mm pad detectors used in SGD. To reduce spatial uncertainty in the depth direction of thick CdTe-DSDs, we implemented a data-driven depth-of-interaction (DOI) correction method using signals from both the anode and cathode sides. This method achieved a DOI resolution of 200 to 240 μm and improved the angular resolution measure to 3.2 deg full width at half maximum at 356 keV. These results demonstrate that miniSGD achieves comparable or superior performance in a more compact configuration, showing the feasibility and potential of thick CdTe-DSDs combined with DOI correction for future gamma-ray missions.
