Abstract:
A curable film-forming coating composition, typically a clearcoat, having improved compatibility over waterborne and solventborne basecoats. The composition includes a film-forming binder comprising a carbamate material, a curing agent, typically a monomeric melamine curing agent, and a hydroxy functional silane component. When used as a clearcoat over a standard pigmented basecoat, the resulting coating provides a substantially wrinkle free appearance and excellent adhesion to both waterborne and solventborne basecoats.
Abstract:
A method for fabricating a thermal inkjet head equipped with a symmetrical heater and the head fabricated by the method are provided. The method incorporates two thick photoresist deposition processes and a nickel electroplating process. The first thick photoresist deposition process is carried out to form an ink chamber in fluid communication with a funnel-shaped manifold and an injector orifice. The second thick photoresist deposition process forms a mold for forming an injector passageway that leads to the injector orifice. The nickel electroplating process provides an orifice plate on top of the inkjet head through which an injector passageway that leads to the injector orifice is provided for injecting ink droplets.
Abstract:
A method for fabricating a capacitor comprises the steps of: forming a lower electrode of a metal over a substrate; forming a capacitor dielectric film of an oxide dielectric film on the lower electrode; depositing a metal film on the capacitor dielectric film; performing a thermal processing in a hydrogen-content atmosphere after the step of depositing the metal film; and patterning the metal film to form an upper electrode of the metal film after the step of performing the thermal processing. Thus, the adhesion between the upper electrode and the capacitor dielectric film is improved, and capacitor characteristics can be improved.
Abstract:
A single-poly EEPROM cell is disclosed with a vertically formed metal-insulator-metal (MIM) coupling capacitor, which serves as a control gate in place of a laterally buried control gate thereby eliminating the problem of junction breakdown, and at the same time reducing the size of the cell substantially. A method of forming the single-poly cell is also disclosed. This is accomplished by forming a floating gate over a substrate with an intervening tunnel oxide and then the MIM capacitor over the floating gate with another intervening dielectric layer between the top metal and the lower metal of the capacitor where the latter metal is connected to the polysilicon floating gate.
Abstract:
A split-gate flash memory cell having improved programming and erasing speed with a tilted trench source, and also a method of forming the same are provided. This is accomplished by forming two floating gates and their respective control gates sharing a common source region. A trench is formed in the source region and the walls are sloped to have a tilt. A source implant is performed at a tilt angle and the trench is lined with a gate oxide layer. Subsequently, a lateral diffusion of the source implant is performed followed by thermal cycling. The lateral enlargement of the diffused source is found to increase the coupling ratio of the split-gate flash memory cell substantially.
Abstract:
A method for fabricating a buried layer pinched collector bipolar, (BPCB), device, sharing several process steps with simultaneously formed CMOS devices, has been developed. The BPCB device fabrication sequence features the use of polysilicon field plates,. placed on field oxide regions, in an area of an N well region in which the field oxide regions are located between subsequent P type, base and N type, collector regions. The use of the polysilicon field plates results in an increase in collector—emitter breakdown voltage, as a result of a reduction in the electric field at the surface underlying the polysilicon field plates. The ability to increase collector —emitter breakdowns, via use of only polysilicon field plates, allows the use of higher N well dopant concentrations, thus resulting in increased frequency responses, (Ft), of the BPCB device, when compared to counterparts fabricated with the lower N well dopant concentrations, where the lower N well dopant concentration is needed to achieve the desired, increased collector emitter breakdowns.
Abstract:
The present invention uses temporary storage of data sub-frames to obviate the need for a multiplicity of driver circuit packages and eliminate the traditional one-to-one association of driver circuit channels with selected data electrodes in the addressing of a flat panel display matrix. Display data signals are serially induced along a controlled velocity signal propagation transmission line to create signal profiles representative of data sub-frames, a data frame being the amount of data required to address a single display row. Individual informational "bits" of the data sub-frame are captured, in timed sequence or in parallel, from the signal profile by the multiplexer assemblies tapped into the transmission line at particular sites along its length. When the assemblies are enabled, the signal profile along the transmission line is exposed to a charge storage capability. The informational bits of the signal profile representing the sub-frame are, consequently, captured. Sequential capturing and storage of data sub-frames continues until a complete data frame of matrix information has been stored. When the bits of plural sub-frames sufficient in total to address an entire row have been stored, the stored data frame is available on the column electrodes and a row select strobe signal closes an electrical path between the multiple data sub-frames available from the columns and a selected row thus recomposing the full data frame at the strobed row to display the data.
