Patent number: 8449018Abstract: A method of forming members of fiber reinforced thermoplastic members via molding, the members including at least one hollow chamber, formed by water injection into the melt in the mold, to stiffen the finished member. The thermoplastic is preferably selected from a group comprising polypropylene, Nylon, PET, ABS, TPO, and thermoplastic polyurethane, while the reinforcing fibers are preferably selected from a group comprising glass, aramid, carbon, and natural fibers. Preferably, the extruded melt is produced such that the average length of the reinforcing fibers is less than four millimeters.Type: GrantFiled: August 29, 2007Date of Patent: May 28, 2013Inventors: Steven Grgac, Hans-Joachim Ludwig, Gerhard Fischer, Martin McLeod

Publication number: 20120135578Abstract: An improved method of doping a workpiece is disclosed. In this method, a film comprising the species to be implanted is introduced to the surface of a planar or three-dimensional workpiece. This film can be grown using CVD, a bath or other means. The workpiece with the film is then subjected to ion bombardment to help drive the dopant into the workpiece. This ion bombardment is performed at elevated temperatures to reduce crystal damage and create a more abrupt doped region.Type: ApplicationFiled: November 14, 2011Publication date: May 31, 2012Applicant: VARIAN SEMICONDUCTOR EQUIPMENT ASSOCIATES, INC.Inventors: Louis Steen, Yuri Erokhin, Hans-Joachim Ludwig Gossman

Patent number: 6632728Abstract: We have found that under certain prescribed conditions a co-implantation process can be effective in increasing the electrical activation of implanted dopant ions. In accordance with one aspect of our invention, a method of making a semiconductor device includes the steps of providing a single crystal semiconductor body, implanting vacancy-generating, ions into a preselected region of the body, implanting dopant ions into the preselected region, the dopant implant forming interstitial defects in the body, and annealing the body to electrically activate the dopant ions. Importantly, in our method the vacancy-generating implant introduces vacancy defects into the preselected region that are effective to annihilate the interstitial defects. In addition, process steps that amorphize the surface of the implanted region are avoided, and the dose of the vacancy-generating implant is made to be greater than that of the dopant implant.Type: GrantFiled: July 16, 2001Date of Patent: October 14, 2003Assignee: Agere Systems Inc.Inventors: Hans-Joachim Ludwig Gossmann, Conor Stefan Rafferty, Tony E. Haynes, Ramki Kalyanaraman, Vincent C. Venezia, Maria Lourdes Pelaz-Montes

Patent number: 6403454Abstract: We have discovered that, contrary to conventional wisdom about forming DP defects, electrical saturation in highly doped 2D layers of Si does not occur. In accordance with one aspect of our invention, free-carrier concentrations in excess of about 7×1020 cm−3 can be attained in single crystal Si layers &dgr;-doped with a Group V element. In one embodiment, free-carrier concentrations in excess of about 2×1021 cm−3 are realized in single crystal Si that is &dgr;-doped with Sb. In another embodiment, the &dgr;-doped layer is formed as an integral part of an FET.Type: GrantFiled: October 29, 1999Date of Patent: June 11, 2002Assignee: Agere Systems Guardian Corp.Inventors: Paul H.

Patent number: 6358824Abstract: A method of fabricating an IC comprises the steps of: (a) forming trench isolation regions in a surface of a semiconductor body; and (b) forming a tub-tie region between at least one pair of the trench isolation regions (when viewed in cross-section) by a process that includes the following steps: (b1) forming a first photolithographic mask that covers and is in registration with the tub-tie region; (b2) implanting ions of a first conductivity-type to form a tub region adjacent the tub-tie region; (b3) removing the first mask; (b4) forming a second photolithographic mask that has an opening that exposes most of the underlying tub-tie region but overlaps a first peripheral section on one side of the tub-tie region; (b5) implanting ions to form a pedestal portion of a second conductivity-type within the tub-tie region; and (b6) implanting ions of the first conductivity-type at an acute (preferably non-zero) angle −⊕ with respect to the normal to the surface to the body so as to form a conductivity-tType: GrantFiled: November 3, 2000Date of Patent: March 19, 2002Assignee: Agere Systems Guardian Corp.Inventors: Hans-Joachim Ludwig Gossmann, Thi-Hong-Ha Vuong

Patent number: 6054342Abstract: An IC comprises a tub of a first conductivity type, at least one transistor embedded in the tub, and a first pair of isolating regions defining therebetween a tub-tie region coupled to the tub. The tub-tie region comprises a cap portion of the first conductivity type and an underlying buried pedestal portion of a second conductivity type. At least a top section of the pedestal portion is surrounded by the cap portion so that a conducting path is formed between the cap portion and the tub. In a CMOS IC tub-ties of this design are provided for both NMOS and PMOS transistors. In a preferred embodiment, the cap portion of each tub-tie comprises a relatively heavily doped central section and more lightly doped peripheral sections, both of the same conductivity type.Type: GrantFiled: June 23, 1999Date of Patent: April 25, 2000Assignee: Lucent Technologies Inc.Inventors: Hans-Joachim Ludwig Gossmann, Thi-Hong-Ha Vuong
