A method of fabricating a photo sensor includes the following steps. First, a substrate is provided, having a conductive layer, a buffer dielectric layer, a patterned semiconductor layer, a dielectric layer, and a planarization layer disposed thereon from bottom to top, wherein the patterned semiconductor layer comprises a first doped region, an intrinsic region, and a second doped region disposed in order. Then, the planarization layer is patterned to form an opening in the planarization layer to expose a portion of the dielectric layer, wherein the opening is positioned on the intrinsic region and portions of the first and the second doped regions. Thereafter, at least a patterned transparent conductive layer is formed in the opening, covering the boundary of the intrinsic region and the first doped region and the boundary of the intrinsic region and the second doped region.

A trench is etched through the layers of pad oxide and silicon nitride that have been deposited on a substrate, the patterned layer of photoresist is left in place. A tilt angle nitrogen implant is performed into the surface of the substrate, a deep shallow STI trench is etched into the surface of the substrate. An oxygen implant of moderate intensity is performed in the created STI trench, the photoresist is removed. An anneal is performed on the implanted oxygen. A liner oxide is grown within the opening, High Density Plasma (HDP) oxide is deposited inside the opening and the top surface of the remaining silicon oxide. CMP is performed to the surface of the HDP oxide down to the surface of the pad oxide that completes the formation of the STI region under the first embodiment of the invention. The invention can be further extended by creating a LOCOS layer at the bottom of the STI opening or by further etching the bottom of the STI opening. Both extensions are to be implemented prior to growing the oxide liner.

A non-volatile memory includes a substrate, a fin structure, a gate structure, a transition layer, and a metal layer. The fin structure is protruded from the substrate. A first source/drain region and a second source/drain region are formed in the fin structure. The gate structure covers a top surface and two lateral surfaces of a part of the fin structure. The gate structure is arranged between the first source/drain region and the second source/drain region. The transition layer is in contact with the second source/drain region. The metal layer is in contact with the transition layer. By setting or resetting the transition layer, a resistance value of the transition layer is correspondingly changed.
