20080285328 | Phase Change Memory - A phase change memory is provided. The method includes forming contact plugs in a first dielectric layer. A second dielectric layer is formed overlying the first dielectric layer and a trench formed therein exposing portions of the contact plugs. A metal layer is formed over surfaces of the trench. One or more heaters are formed from the metal layer such that each heater is formed along one or more sidewalls and a portion of the bottom of the trench, wherein the portion of the heater along the sidewalls does not include a corner region of adjacent sidewalls. The trench is filled with a third dielectric layer, and a fourth dielectric layer is formed over the third dielectric layer. Trenches are formed in the fourth dielectric layer and filled with a phase change material. An electrode is formed over the phase change material. | 11-20-2008 |
20080291172 | COMPACT UNIVERSAL KEYBOARD - A keyboard type input device used in conjunction with a wristwatch or a portable telephone has multiple key positions provided as character entry keys. Each key corresponds to one key in the selected row of the conventional QWERTY keyboard. A second set of control buttons provide for the selection of which row of a conventional QWERTY keyboard are represented by the character keys in addition to other functions such as case shift, and alpha-numerical control functions. A selected row is shown on a display, as visual feedback. Alternatively the keys are implemented as LCDs with pressure sensors and the characters of the selected row are displayed directly on the corresponding key positions. The keyboard finds particular use in portable devices as it demands less space than traditional keyboards. | 11-27-2008 |

20080253025 | METHOD AND APPARATUS FOR PROVIDING AN ADDITIONAL GROUND PAD AND ELECTRIC AL CONNECTION FOR GROUNDING A MAGNETIC RECORDING HEAD - Method and apparatus are presented for electrically coupling a slider to ground. In one embodiment, a bonding pad is provided on a side of the slider body separate from the bonding pad(s) used for read/write signals. This separate bonding pad is electrically coupled within the slider body to components that are to be coupled to ground. A separate conductor provided on the suspension (e.g., a trace, a flex circuit, etc.) may be electrically coupled to the separate bonding pad via gold ball bonding. The conductor is also coupled to ground in the hard-disk drive device (e.g., via the preamplifier). The use of the separated bonding pad and trace may negate the need to use a conductive adhesive to electrically ground the slider via its attachment to the tongue of a slider. | 10-16-2008 |
20090201611 | Perpendicular write head with tapered main pole - Prior art designs of single pole writers have been limited by premature saturation at the tip. This limits the head field that can be achieved without simultaneously widening the write profile. This problem has bee solved by means of a vertical main pole whose thickness has its conventional value a short distance from the tip but that tapers down to a significantly reduced value as it approaches the tip. A process for manufacturing this tapered tip design is also presented. | 08-13-2009 |
