Publication number: 20010001729Abstract: In wafer semiconductor manufacture, a method of etching an arsenic doped polysilicon layer down to a patterned boro-phospho-silicate-glass (BPSG) layer provided with a plurality of openings with an uniform etch rate is disclosed. The method relies on a combination of both system and process improvements. The system improvement consists to hold the wafer in the reactor during the etch process with an electrostatic chuck device to have a perfect plasma environment around and above the wafer. On the other hand, the process improvement consists in the use of a non dopant sensitive and not selective chemistry. A NF3/CHF3/N2 gas mixture with a 11/8.6/80.4 ratio in percent is adequate in that respect. The etch time duration is very accurately controlled by an optical etch endpoint detection system adapted to detect the intensity signal transition of a CO line at the BPSG layer exposure. The process is continued by a slight overetching.Type: ApplicationFiled: December 18, 1998Publication date: May 24, 2001Inventors: FRANCOLS LEVERD, RENZO MACCAGNAN, ERIC MASS

Publication number: 20010001730Abstract: A method for forming HSG polysilicon with reduced dielectric bridging and increased capacitance. A first polysilicon layer is deposited and doped with impurities to increase conductivity. A second polysilicon layer is deposited at a reduced temperature to cause a nucleation of the second polysilicon layer. Grains are formed on the surface of the second polysilicon layer as a result of the nucleation. Next a wet etch is performed to remove portions of the polysilicon grains and portions of the first polysilicon layer. The duration of the wet etch is controlled to retain a roughened surface area. The size of the grains decreases during the wet etch and the distance between the grains increases. A dielectric layer is deposited to overlie the rough polysilicon following the wet etch. The thickness of the dielectric layer tends to be uniform thereby reducing bridging of the dielectric between the grains of the of the polysilicon.Type: ApplicationFiled: February 25, 1999Publication date: May 24, 2001Inventor: THOMAS A FIGURA

Publication number: 20010001770Abstract: A golf club includes an electroactive assembly attached to the club and electrically tuned to capture energy from one or more vibrational modes with high efficiency. More generally, a sports implement includes an electroactive element, such as a piezoceramic sheet attached to the implement, and a circuit attached to the electroactive element. The circuit may be a shunt, or may include processing such as amplification and phase control to apply a driving signal which may compensate for strain sensed in the implement, or may simply alter the stiffness to affect performance. The electroactive element is located in a region of high strain to apply damping, and may include plural subassemblies mounted to capture energy in different planes, or to capture an asymmetric strain distribution while maintaining structural symmetry. In a ski the element captures between about one and five percent of the strain energy of the ski.Type: ApplicationFiled: January 12, 2001Publication date: May 24, 2001Inventors: Ronald Spangler, David Gilbert, Carl Prestia, Emanuele Bianchini, Kenneth B.

Publication number: 20010001771Abstract: Disclosed is a set of golf clubs. The clubs are divided into at least a first group and at least a second group of golf clubs. The first group desirably comprises a plurality of club heads each having a main body of low density metallic material. The second group of golf clubs desirably comprises a plurality of club heads each having a main body of higher density metallic material than the density of the metallic material of the main body of each of the heads of the first group. The first group of clubs desirably comprises lower numbered clubs than the second group of clubs.Type: ApplicationFiled: November 29, 2000Publication date: May 24, 2001Inventors: Michael R. Peters, Richard L. Rugge, Bret Wahl

Publication number: 20010001776Abstract: A multi-function exercise machine includes a base structure that defines an exercise position. A lever is provided on the base structure for pivotal movement about an axis. The axis is located between opposite end portions of the lever. A handle is associated with the lever so as to be engaged by an exerciser to move the handle about the axis in an upward direction to a raised position and in a downward direction toward to a raised position and in a downward direction toward a lowered position. A first connector is provided on one end portions of the lever to apply selectively a first resistance against movement of the handle in the upward direction. A second connector is provided on the opposite end portion of the lever to apply selectively a second resistance against movement of the handle in the downward direction.Type: ApplicationFiled: January 18, 2001Publication date: May 24, 2001Inventor: Gary Allen Jones
