Patent number: 6656539Abstract: An element is deposited by flowing a gas through a solid donor compound that includes the element, and over a substrate. The flow of gas deposits a film of a few monolayers of donor compound on the substrate. An optical radiation source (e.g., a femtosecond laser) which produces optical radiation at an instantaneous intensity sufficient to cause non linear or otherwise enhanced interaction between optical radiation photons and the donor compound is used to decompose the donor compound and deposit the metal on the substrate. After an initial deposit of the donor compound is produced, optical radiation can be absorbed and heat the substrate in the localized area of the deposit in order to accelerate the deposition process by thermally decomposing the donor compound.Type: GrantFiled: November 13, 2000Date of Patent: December 2, 2003Assignee: International Business Machines CorporationInventors: Richard A. Haight, Peter P. Longo, Alfred Wagner

Patent number: 6190836Abstract: A method of repairing defects on masks includes the step of providing a coating on the mask to prevent damage to clear regions of the mask from laser ablation splatter, laser ablation caused quartz pitting, laser deposition staining, and FIB caused gallium staining. The coating is a metal, a polymer, or a carbon material. The coating is formed on clear regions of the mask as well as either over or under the light absorbing material of the mask. A coating comprising a thin copper layer significantly improves imaging with the ion beam while protecting clear regions of the mask from FIB stain. A coating formed of a photosensitive polymer is used to etch opaque defects. While wanted opaque regions adjacent an opaque defect are also etched in this etch step, these created clear defects are then repaired in a subsequent FIB deposition step while a copper coating protects adjacent clear regions from FIB stain.Type: GrantFiled: April 28, 2000Date of Patent: February 20, 2001Assignee: International Business Machines CorporationInventors: Brian J. Grenon, Richard A. Haight, Dennis M. Hayden, Michael S. Hibbs, J. Peter Levin, Timothy E. Neary, Raymond E. Rochefort, Dennis A. Schmidt, Jacek G. Smolinski, Alfred Wagner

Patent number: 5798529Abstract: A focused ion beam metrology device and method are disclosed. A focused ion beam is used to measure dimensions of semiconductor features, such as top-down linewidth measurement. Low intensity focused ion beams form top view images of the semiconductor. High intensity focused ion beams etch the semiconductor in the presence of etch-enhancing material. A crater is etched to expose a cross-section the of semiconductor. The cross-section is imaged by directing low intensity focused ion beams toward the cross-section. This may be achieved by tilting the semiconductor. A three dimensional profile of a feature may be formed by successively etching the feature top surface and forming a top view image thereof. Overlaying the successive top view images forms the three dimensional profile.Type: GrantFiled: May 28, 1996Date of Patent: August 25, 1998Assignee: International Business Machines CorporationInventor: Alfred Wagner

Patent number: 5159170Abstract: A transmission grid is disposed in a conventional focussed ion beam system which includes an ion beam source emitter or ion gun, electrodes to turn the ion beam off and on, a beam defining aperture and electrostatic lenses to focus the ion beam onto a target. The elements of the ion beam system are disposed in a chamber which is provided with an inlet port and an outlet port. Gas is introduced into chamber via the inlet port where it is ionized by the ion beam into an ion plasma to be used to deposit materials onto the target. The transmission grid, is interposed which is a fine mesh, passive element is located in the path of the ion beam and reduces the ion beam current density by a desired value. The transmission grid may be configured with a variety of different transmissions so the current density can be adjusted in different increments depending on the gas/type of deposition to be performed.Type: GrantFiled: April 26, 1991Date of Patent: October 27, 1992Assignee: International Business Machines CorporationInventors: James P.

Patent number: 5149974Abstract: An ion beam structure includes a gas container, such as a cylindrical can having first and second apertures through the center of the top and bottom walls respectively of the container such that a narrow ion beam is passed through the apertures and the center axis of the can and onto a target specimen such as a mask or chip or other article of manufacture disposed closely below the bottom of the can. The can may further include deflection means for applying voltages and/or magnetic fields to locations on the can (i.e., top, bottom, sides) to direct secondary charged particles such as electrons emitted from the specimen onto an electron detection means such that the structure functions as an imaging system. The electric and/or magnetic fields may be employed to increase the collection efficiency of the detector and thereby improve the quality of the image by increasing the signal to noise ratio.Type: GrantFiled: October 29, 1990Date of Patent: September 22, 1992Assignee: International Business Machines CorporationInventors: Steven J.
