  • Patent number: 7771606
    Abstract: A pulsed plasma system with pulsed reaction gas replenish for etching semiconductor structures is described. In an embodiment, a portion of a sample is removed by applying a pulsed plasma etch process. The pulsed plasma etch process comprises a plurality of duty cycles, wherein each duty cycle represents the combination of an ON state and an OFF state of a plasma. The plasma is generated from a reaction gas, wherein the reaction gas is replenished during the OFF state of the plasma, but not during the ON state. In another embodiment, a first portion of a sample is removed by applying a continuous plasma etch process. The continuous plasma etch process is then terminated and a second portion of the sample is removed by applying a pulsed plasma etch process having pulsed reaction gas replenish.

  • Patent number: 7754610
    Abstract: A method of plasma etching tungsten silicide over polysilicon particularly useful in fabricating flash memory having both a densely packed area and an open (iso) area requiring a long over etch due to microloading. Wafer biasing is decreased in the over etch. The principal etchant include NF3 and Cl2. Argon is added to prevent undercutting at the dense/iso interface. Oxygen and nitrogen oxidize any exposed silicon to increase etch selectivity and straightens the etch profile. SiCl4 may be added for additional selectivity.
