The substrate (30) is then annealed. The annealing process melts the amorphous region (32) and allows the dopants precipitated on the major surface (31) to diffuse into the substrate (30). The annealing process also crystallizes the semiconductor material the amorphous region (32). The substrate (30) becomes a single crystal semiconductor substrate with multiple doped regions (54, 57) therein. The depth of the doped regions (54, 57) is substantially equal to the depth of the amorphous region (32) before annealing.

  • Patent number: 6232048
    Abstract: A method of preparing a narrow photoresist line by first forming a resist pattern on a substrate, wherein a resist line is designed to have a width “w” in excess of a desired width “w1” The resist is then subjected to ionic bombardment with ionized particles in a direction normal to the planar surface of a resistant substrate. The ionic bombardment causes formation of a hardened “chemically less reactive” skin on the exposed top surface of the photoresist. The resist is then subjected to an isotropic etch procedure. Due to the hardened top surface of the narrow pattern, the side wall erode at a faster rate than the top, causing a narrowing of the line width, while retaining a more substantial photoresist thickness than would occur if the top surface would not be hardened in advance of the etch procedure.

  • Patent number: 6086949
    Abstract: A thin film disk and a method for producing the disk having an overcoat with two thickness regions. The thicker overcoat region can be used as a start/stop or loading zone and the thinner overcoat region can be used over the data recording area. This provides increased wear resistance while allowing improved magnetic performance through a reduction in the thickness of the overcoat over the data recording area. The dual thickness regions can be formed using different embodiments of the method. One method sputter deposits a relatively thick layer of overcoat material over the entire disk surface, masks off the portion of the disk for the thick layer, etches the unmasked area to reduce or eliminate the overcoat from the unmasked area, then deposits a second relatively thin layer of overcoat material over the entire surface.

  • Patent number: 6063436
    Abstract: The uniformity of individual layers of multiple coating materials deposited on a substrate in a vacuum deposition process (such as for manufacturing mirrors for use in ring laser gyroscopes) is improved by an apparatus and method that include changing the masks placed in front of the substrate upon which the coating materials are to be deposited. Separate masks are tuned for each particular coating material to compensate for the unique plume shape of the material, and provide a uniform deposition of that particular coating material. Each mask is positioned in front of the substrate when the material for which the mask has been tuned is being deposited. The masks are changed when the coating material is changed, without venting the chamber.

  • Patent number: 6063246
    Abstract: A method for depositing carbon films on membranes used in masks for X-ray or corpuscular projection, e.g. electron or ion beam, lithography is proposed in which sputtering is used and the membranes serving as sputter substrates are positioned in the off-axis configuration relative to the sputter targets. The carbon films thus produced have a compressive stress of the order of 10 MPa or below. For modifying the properties of carbon films after deposition, e.g. the deactivation of chemically reactive sites or stabilization of stress, ion bombardment with helium ions can be employed. This method anticipates changes in the film due to initial irradiation and serves to reach a plateau in which the stress varies only a little, i.e. within about 1 MPa or less.

  • Patent number: 5980974
    Abstract: An improved coated orthopaedic implant component is disclosed. The implant may be coated with platinum, iridium or other metals for improved characteristics. Ion beam coating orthopaedic parts by ion implanting the parts with zirconium ions while the parts are immersed in an oxygen-containing background gas is also disclosed. The adhesion of the graded interface zirconium oxide surface layer so formed is further improved by the initial removal of surface contamination using an ion bombardment and the deposition of an intermediate layer of platinum or similar metal or silicon between the orthopaedic metal component and the zirconium oxide. Furnace heating results in atomic interdiffusion to enhance adhesion between the surfaces. The zirconium oxide provides a low friction, low wear articulating surface. The graded interface may be characterized by a blackish color and a transition between pure zirconium oxide and pure intermediate layer that extends over a thickness of hundreds of Angstroms.

  • Patent number: 5882738
    Abstract: An ion implant process is disclosed for forming an amorphous structure in a semiconductor metallization barrier layer, which barrier may be a pure metal barrier, such as titanium, tantalum, tungsten, or metal compound barrier, such as titanium nitride, or titanium-tungsten. The implant is preferably an ion of the barrier metal being used, which is implanted such that an amorphous (texture-less non-crystalline) layer is produced. Other implant species, such as nitrogen or noble gases, such as neon or argon may also be used. Subsequent deposition of the interconnect metallization (typically Al or Cu) results in an interconnect metal structure having a high degree of texture which is characterized by a very narrow distribution of crystallographic orientations in the Al or Cu film. The highly textured Al or Cu metallization results in optimizing the interconnect metal for maximum electromigration performance.

  • Patent number: 5858471
    Abstract: A deposition process provides selective areal deposition on a substrate surface having separate areas of different materials comprises forming a plasma over the substrate, injecting coating species into the plasma by either of sputtering or gaseous injection, adding a reactive gas for altering surface binding energy at the coating surface, and biasing the substrate during deposition to bombard the substrate with ionic species from the plasma. Surface binding energy is altered, in the general case, differently for the separate areas, enhancing selectivity. Bias power is managed to exploit the alteration in surface binding energy. In the case of gaseous injection of the coating species, and in some cases of sputtering provision of the coating material, the temperature of the substrate surface is managed as well. In an alternative embodiment, selectivity is to phase of the coating material rather than to specific areas on the substrate, and a selected phase may be preferentially deposited on the substrate.

  • Patent number: 5858623
    Abstract: A method for forming a patterned photoresist layer. There is first provided a substrate. There is then formed over the substrate a blanket photoresist layer. The blanket photoresist layer is then implanted with a first ion beam to form an ion implanted blanket photoresist layer. The first ion beam employs a first ion having a first energy and a first dose sufficient such that an ion implanted patterned photoresist layer formed from the ion implanted blanket photoresist layer will not substantially outgas when the ion implanted patterned photoresist layer is exposed to a second beam. The ion implanted blanket photoresist layer is then patterned to form the ion implanted patterned photoresist layer. The method may be employed in selective high energy beam processing of the substrate. The method is particularly suited to selective high energy ion implant processing of semiconductor substrates employed within integrated circuit microelectronics fabrications.

  • Patent number: 5855950
    Abstract: A method is disclosed for ion beam treating orthopaedic parts by ion implanting the parts with aluminum ions while the parts are immersed in an oxygen-containing background gas. When the parts are at sufficiently elevated temperature, a highly adherent layer of aluminum oxide is grown which provides a low friction, low wear articulating surface. The interface between the semi-pure aluminum oxide and the substrate orthopaedic part consists of a composition which gradually grades with depth between the grown aluminum oxide and the pure substrate material. This interface has a thickness dependent on the processing parameters, typically hundreds of Angstroms. In an alternative embodiment, the thickness of the alumina layer may be increased by simultaneously depositing aluminum oxide on the parts.
