摘要:
The invention discloses a preparation method for a printing OLED display, comprising the following steps: preparing a hole injection layer, a hole transfer layer or an electron blocking layer on an anodic substrate; forming a soluble fluorine-containing insulation layer with a printing method to encapsulate the whole substrate; performing inkjet printing on the soluble fluorine-containing insulation layer with a fluorine solvent to wash to expose all sub-pixel pits; performing inkjet printing with the solution drops of luminescent materials to form a RGB luminescent layer in the sub-pixel pits; preparing an electron injection layer, an electron transfer layer or a hole blocking layer; preparing a cathode with a printing method or an evaporating method, and finally performing encapsulation to complete the preparation of the single printing OLED display.
摘要:
A structure and a process for a self-aligned vertical PNP transistor for high performance SiGe CBiCMOS process. Embodiments include SiGe CBiCMOS with high-performance SiGe NPN transistors and PNP transistors. As the PNP transistors and NPN transistors contained different types of impurity profile, they need separate lithography and doping step for each transistor. The process is easy to integrate with existing CMOS process to save manufacturing time and cost. As plug-in module, fully integration with SiGe BiCMOS processes. High doping Polysilicon Emitter can increase hole injection efficiency from emitter to base, reduce emitter resistor, and form very shallow EB junction. Self-aligned N+ base implant can reduce base resistor and parasitical EB capacitor. Very low collector resistor benefits from BP layer. PNP transistor can be Isolated from other CMOS and NPN devices by BNwell, Nwell and BN+ junction.
