摘要： A composite high dielectric constant (high-k) gate dielectric includes a stack of a doped high-k gate dielectric and an undoped high-k gate dielectric. The doped high-k gate dielectric can be formed by providing a stack of a first high-k dielectric material layer and a dopant metal layer and annealing the stack to induce the diffusion of the dopant metal into the first high-k dielectric material layer. The undoped high-k gate dielectric is formed by subsequently depositing a second high-k dielectric material layer. The composite high-k gate dielectric can provide an increased gate-leakage oxide thickness without increasing inversion oxide thickness.

摘要： Forming a shallow trench capacitor in conjunction with an FET by forming a plurality of STI trenches; for the FET, implanting a first cell well having a first polarity between a first and a second of the STI trenches; for the capacitor, implanting a second cell well having a second polarity in an area of a third of the STI trenches; removing dielectric material from the third STI trench; forming a gate stack having a first portion located between the first and the second of the STI trenches and a second portion located over and extending into the third trench; and performing a source/drain implant of the same polarity as the second cell well, thereby forming a FET in the first cell well, and a capacitor in the second cell well. The second polarity may be opposite from the first polarity. An additional implant may reduce ESR in the second cell well.

摘要： A deep trench is formed to a depth midway into a buried insulator layer of a semiconductor-on-insulator (SOI) substrate. A top semiconductor layer is laterally recessed by an isotropic etch that is selective to the buried insulator layer. The deep trench is then etched below a bottom surface of the buried insulator layer. Ion implantation is performed at an angle into the deep trench to dope the sidewalls of the deep trench beneath the buried insulator layer, while the laterally recessed sidewalls of the top semiconductor layer are not implanted with dopant ions. A node dielectric and trench fill materials are deposited into the deep trench. A buried strap has an upper buried strap sidewall that is offset from a lower buried strap sidewall and a deep trench sidewall.
