Patent number: 9576788Abstract: A method of removing an amorphous silicon/silicon oxide film stack from vias is described. The method may involve a remote plasma comprising fluorine and a local plasma comprising fluorine and a nitrogen-and-hydrogen-containing precursor unexcited in the remote plasma to remove the silicon oxide. The method may then involve a local plasma of inert species to potentially remove any thin carbon layer (leftover from the photoresist) and to treat the amorphous silicon layer in preparation for removal. The method may then involve removal of the treated amorphous silicon layer with several options possibly within the same substrate processing region. The bottom of the vias may then possess exposed single crystal silicon which is conducive to epitaxial single crystal silicon film growth. The methods presented herein may be particularly well suited for 3d NAND (e.g. VNAND) device formation.Type: GrantFiled: April 24, 2015Date of Patent: February 21, 2017Assignee: Applied Materials, Inc.Inventors: Jie Liu, Seung Park, Anchuan Wang, Zhenjiang Cui, Nitin K.

Patent number: 9520267Abstract: The angular ion distribution in plasma processing is controlled using a bias voltage frequency. In one example, a plasma containing gas ions is generated in a plasma chamber. The plasma sheath is modified using an aperture disposed between the plasma sheath and the workpiece so that the plasma sheath takes a shape above the aperture. An oscillating radio frequency bias voltage is generated and applied to a workpiece holder. The workpiece holder applies the bias voltage to the workpiece to generate a workpiece bias voltage with respect to the plasma to attract ions across the plasma sheath toward the workpiece. The aperture and the frequency of the bias voltage control an angle at which the ions are attracted toward the workpiece.Type: GrantFiled: August 25, 2014Date of Patent: December 13, 2016Assignee: Applied Mateirals, Inc.Inventors: Ludovic Godet, Jun Xue, Prashanth Kothnur, Umesh M.

Patent number: 9520270Abstract: Techniques herein include methods for curing a layer of material (such as a resist) on a substrate to enable relatively greater heat reflow resistance. Increasing reflow resistance enables successful directed self-assembly of block copolymers. Techniques include receiving a substrate having a patterned photoresist layer and positioning this substrate in a processing chamber of a capacitively coupled plasma system. The patterned photoresist layer is treated with a flux of electrons by coupling negative polarity direct current power to a top electrode of the plasma processing system during plasma processing. The flux of electrons is accelerated from the top electrode with sufficient energy to pass through a plasma and its sheath, and strike the substrate such that the patterned photoresist layer changes in physical properties, which can include an increased glass-liquid transition temperature.Type: GrantFiled: July 25, 2014Date of Patent: December 13, 2016Assignee: Tokyo Eelctron LimitedInventors: Nihar Mohanty, Akiteru Ko, Chi-Chun Liu
