    摘要: A recessed channel transistor comprises a semiconductor substrate having a trench isolation structure, a gate structure having a lower block in the semiconductor substrate and an upper block on the semiconductor substrate, two doped regions positioned at two sides of the upper block and above the lower block, and an insulation spacer positioned at a sidewall of the upper block and having a bottom end sandwiched between the upper block and the doped regions. In particular, the two doped regions serves as the source and drain regions, respectively, and the lower block of the gate structure serves as the recessed gate of the recessed channel transistor.

    摘要: An atomic layer deposition apparatus comprises a reaction chamber, a heater configured to heat a semiconductor wafer positioned on the heater, an oxidant supply configured to deliver oxidant-containing precursors having different oxidant concentrations to the reaction chamber, and a metal supply configured to deliver a metal-containing precursor to the reaction chamber. The present application also discloses a method for preparing a dielectric structure comprising the steps of placing a substrate in a reaction chamber, performing a first atomic layer deposition process including feeding an oxidant-containing precursor having a relatively lower oxidant concentration and a metal-containing precursor to form an thinner interfacial layer on the substrate, and performing a second atomic layer deposition process including feeding the oxidant-containing precursor having an oxidant concentration higher than that used to grow the first metal oxide layer and the metal-containing precursor into the reaction chamber.
