  • Patent number: 7307703
    Abstract: An etching end point of a plasma etch is determined by defining an etch-stop condition. A layer formed on a substrate is etched using a plasma. A luminous intensity of the plasma is measured to determine a first luminous intensity. The luminous intensity is measured again after a predetermined time to determine a second luminous intensity. A determination is made whether a disturbance occurs. Compensation is applied to the measured luminous intensity if the disturbance occurs. A determination is made whether the measured luminous intensity or the compensated luminous intensity satisfies the etch stop condition.

  • Publication number: 20070278518
    Abstract: A method of fabricating AlGaN/GaN enhancement-mode heterostructure field-effect transistors (HFET) using fluorine-based plasma immersion or ion implantation. The method includes: 1) generating gate patterns; 2) exposing the AlGaN/GaN heterostructure in the gate region to fluorine-based plasma treatment with photoresist as the treatment mask in a self-aligned manner; 3) depositing the gate metal to the plasma treated AlGaN/GaN heterostructure surface; 4) lifting off the metal except the gate electrode; and 5) high temperature post-gate annealing of the sample. This method can be used to shift the threshold voltage of a HFET toward a more positive value, and ultimately convert a depletion-mode HFET to an enhancement-mode HFET (E-HFET).
