Abstract
Development and application of Silicon-on-Insulator (SOI) monolithic pixel devices has been significantly boosted in recent years. After a brief review of the recent SOI development activities in various sciences, we detail the test-beam results achieving a sub-micron spatial resolution, 0.65 m, first time by a semi-conductor device, with Fine-Pixel Detector (FPIX) which has a pixel size of 8x8 m pixel size and thickness of 500 m. Another device SOFIST with pixels of 20x20 m and thickness of 500m showed a spatial resolution of ~1.2 m. Thinner devices as required for the ILC experiment are expected to be an excellent candidate even with reduced signal-to-noise ratio.
