摘要： A masking layer is applied over a top semiconductor layer and patterned to expose in an opening a shallow trench isolation structure and a portion of a top semiconductor region within which a first source/drain region and a body is to be formed. Ions are implanted into a portion of a buried insulator layer within the area of the opening to form damaged buried insulator region. The shallow trench isolation structure is removed and the damaged buried insulator region is etched selective to undamaged buried insulator portions to form a cavity. A dielectric layer is formed on the sidewalls and the exposed bottom surface of the top semiconductor region and a back gate filling the cavity is formed. A contact is formed to provide an electrical bias to the back gate so that the electrical potential of the body and the first source/drain region is electrically modulated.

摘要： Trench type PIN photodetectors are formed by etching two sets of trenches simultaneously in a semiconductor substrate, the wide trenches having a width more than twice as great as the narrow trenches by a process margin; conformally filling both types of trenches with a sacrificial material doped with a first dopant and having a first thickness slightly greater than one half the width of the narrow trenches, so that the wide trenches have a remaining central aperture; stripping the sacrificial material from the wide trenches in an etch that removes a first thickness, thereby emptying the wide trenches; a) filling the wide trenches with a second sacrificial material of opposite polarity; or b) doping the wide trenches from the ambient such as by gas phase doping, plasma doping, ion implantation, liquid phase doping, infusion doping and plasma immersion ion implantation; diffusing the dopants into the substrate, forming p and n regions of the PIN diode; removing the first and the second sacrificial materials, and filling both the wide and the narrow sets of trenches with the same conductive material in contact with the diffused p and n regions.
