Title: Method of precisely modifying predetermined surface layers of a workpiece by cluster ion impact therewith

Full Record
Other Related Research

Abstract

A method of precisely modifying a selected area of a workpiece by producing a beam of charged cluster ions that is narrowly mass selected to a predetermined mean size of cluster ions within a range of 25 to 10.sup.6 atoms per cluster ion, and accelerated in a beam to a critical velocity. The accelerated beam is used to impact a selected area of an outer surface of the workpiece at a preselected rate of impacts of cluster ions/cm.sup.2 /sec. in order to effect a precise modification in that selected area of the workpiece.

Methods for the Precise Locating and Forming of Arrays of Curved Features into a Workpiece

Patent Gill, David Dennis [Albuquerque, NM]; Keeler, Gordon A [Albuquerque, NM]; Serkland, Darwin K [Albuquerque, NM]; ...

Methods for manufacturing high precision arrays of curved features (e.g. lenses) in the surface of a workpiece are described utilizing orthogonal sets of inter-fitting locating grooves to mate a workpiece to a workpiece holder mounted to the spindle face of a rotating machine tool. The matching inter-fitting groove sets in the workpiece and the chuck allow precisely and non-kinematically indexing the workpiece to locations defined in two orthogonal directions perpendicular to the turning axis of the machine tool. At each location on the workpiece a curved feature can then be on-center machined to create arrays of curved features on themore » « less

Screening method for selecting semiconductor substrates having defects below a predetermined level in an oxide layer

Patent Warren, William L [Albuquerque, NM]; Vanheusden, Karel J. R. [Albuquerque, NM]; Schwank, James R [Albuquerque, NM]; ...

A method for screening or qualifying semiconductor substrates for integrated circuit fabrication. The method comprises the steps of annealing at least one semiconductor substrate at a first temperature in a defect-activating ambient (e.g. hydrogen, forming gas, or ammonia) for sufficient time for activating any defects within on oxide layer of the substrate; measuring a defect-revealing electrical characteristic of at least a portion of the oxide layer for determining a quantity of activated defects therein; and selecting substrates for which the quantity of activated defects is below a predetermined level. The defect-revealing electrical characteristic may be a capacitance-versus-voltage (C-V) characteristic ormore » « less

Apparatus and method for forming a workpiece surface into a non-rotationally symmetric shape

Patent Dow, Thomas A [Raleigh, NC]; Garrard, Kenneth P [Raleigh, NC]; Moorefield, II, George M. (Raleigh, NC); ...

A turning machine includes a controller for generating both aspherical and non-symmetrical shape components defining the predetermined shape, and a controller for controlling a spindle and a positionable cutting blade to thereby form a predetermined non-rotationally symmetric shape in a workpiece surface. The apparatus includes a rotatable spindle for rotatably mounting the workpiece about an axis, a spindle encoder for sensing an angular position of the rotating workpiece, the cutting blade, and radial and transverse positioners for relatively positioning the cutting blade and workpiece along respective radial and transverse directions. The controller cooperates with a fast transverse positioner for positioningmore » « less
