Patent TW-434110-B (TW)
Title: Multi-step chemical mechanical polishing
Inventor: HOLLAND KAREY
IPC: B24B37/04
Filed: 2000-05-24
Granted: 2001-05-16
Abstract: A multi-step CMP system is used to polish a wafer to form metal interconnects in a dielectric layer upon which barrier and metal layers have been formed. A first polish removes an upper portion of the metal layer using a first slurry and a first set of polishing parameters, leaving residual metal within the dielectric layer to serve as the metal interconnects. A second polish of the wafer on the same platen and polishing pad removes portions of the barrier layer using a second slurry under a second set of polishing parameters. The second polish clears the barrier layer from the upper surface of the dielectric layer, thereby forming the metal interconnect. To reduce dishing and dielectric erosion, the second slurry is selected so that the barrier layer is removed at a faster rate than the residual metal within the dielectric layer. A cleaning step may be optionally performed between the first and second polishes. Further, the first polish may include a soft landing step to further reduce dishing and dielectric erosion. Alternatively, the first polish may be used to remove portions of the metal and barrier layers, leaving residual metal in the dielectric layer to serve as the metal interconnect. A second polish using a dielectric slurry is then performed to reduce microscratches.

Title: Hearing aid with large diaphragm microphone element including a printed circuit board
Inventor: SJURSEN WALTER P
IPC: H04R25/00
Filed: 2000-01-07
Granted: 2001-06-16
Abstract: A disposable-type hearing aid uses a relatively large single diaphragm or a large single diaphragm subdivided into a plurality of smaller active diaphragm areas obtained using a grate-like back support plate with ridges which contact and divide the diaphragm into the several smaller active diaphragm areas. The diaphragm and a backplate are enclosed in a metal housing and are disposed proximal and parallet to a shell-like hearing aid enclosure having sound inlets. The metal housing is closed at an end opposite the sound inlets by a printed circuit board (PCB) forming an acoustical seal for a back volume of the microphone. The PCB also carries substantially all the electronic components for the hearing aid thereon. The PCB  has a ground plane in contact with the housing whereby the PCB also acts as an EMI shield. An electrical connection is formed in various ways between the back support plate and the PCB during assembly of the metal housing and components with the PCB. Mass production of disposable hearing aids with large diaphragms and relatively low noise levels is thus possible using this invention.

Abstract: A method, system, and apparatus for managing input/output drawers within a data processing system is provided. In one embodiment, a service processor assigns a unique location identifier to each of a plurality of input/output drawers. Each of these unique location identifiers is stored in memory. The unique location identifier is used by the operating system to identify the input/output drawers in the system regardless how these input/output drawers are interconnected by cables. In this embodiment, the system firmware assigns another unique PCI-bridge identifier to each of a plurality of PCI Host bridges (PHBs) from all input/output drawers. The unique PCI-bridge identifier is used by the operating system to perform input/output processes to input/output devices associated with the plurality of PCI Host bridges from all input/output drawers such that the operating systems ODM object for each of the PCI Host bridges from an I/O drawer remains the same regardless of how the I/O drawer is interconnected in the system. When a new input/output drawer is added to the data processing system, the service processor assigns a new unique location identifier to the new input/output drawer ensuring that the unique location identifiers previously assigned to other I/O drawers are not used to identify the new I/O drawer.
