Abstract: Apparatus (100) for an improved etch process. A power source (1500, 1506) alternates between high and low power cycles to produce and sustain a plasma discharge. The high power cycles couple sufficient power into the plasma to produce a high density of ions (>/=10 cm ) for etching. The low power cycles allow electrons to cool off to reduce the average random (thermal) electron velocity in the plasma. The low power cycle is limited in duration as necessary to prevent excessive plasma loss to the walls (116a, 116b) or due to recombination of negative and positive ions. A separate power (152) source alternates between high and low power cycles to accelerate ions toward the substrate (107) being etched. In one embodiment, a strong bias is applied to the substrate in short bursts. Multiple burst occur during the average transit time for an ion to cross the plasma sheath and reach the substrate surface. Ions are pulsed toward the surface for etching.

Abstract: A high plasma density etch process for etching an oxygen-containing layer overlying a non-oxygen containing layer on a workpiece in a plasma reactor chamber, by providing a chamber ceiling overlying the workpiece and containing a semiconductor material, supplying into the chamber a process gas containing etchant precursor species, polymer precursor species and hydrogen, applying plasma source power into the chamber, and cooling the ceiling to a temperature range at or below about 150 degrees C. The etchant and polymer precursor species contain fluorine, and the chamber ceiling semiconductor material includes a fluorine scavenger precursor material. Preferably, the process gas includes at least one of CHF3 and CH2F2. Preferably, the process gas further includes a species including an inert gas, such as HeH2 or Ar. If the chamber is of the type including a heated fluorine scavenger precursor material, this material is heated to well above the polymer condensation temperature, while the ceiling is cooled. In some cases, the plasma source power applicator is an inductive antenna overlying the semiconductor ceiling, and the ceiling has a cooling/heating apparatus contacting the ceiling through semiconductor rings. The inductive antenna in this case constitutes inductive elements between adjacent ones of the semiconductor rings.

Abstract: A method and apparatus are disclosed employing electron cyclotron resonant (ECR) heating to produce plasma for applications including but not limited to chemical vapor deposition and etching. A magnetic field is formed by magnets (20) circumferentially arranged about a cylindrical and symmetrical chamber (12) with microwave power (44) injected perpendicularly to a longitudinal axis (14) of the chamber (12) for preventing line-of-sight communication of resulting energetic electron through an outlet (50) at one axial end of the chamber (12). The circumferential magnets (20) cause precessing of the electrons resulting in greatly increased plasma density and ion flux or current density even at low pressures which are preferably maintained for establishing unidirectionality or anisotropic plasma characteristics. A magnetic field free region (60) is formed between the plasma forming region (44) and the circumferential magnets (20) in order to also produce uniformity of plasma distribution in a plasma stream approaching the outlet.
