A p channel thin-film transistor (TFT) made of directly deposited microcrystalline silicon (uc-Si). The p TFT is integrated with its n channel counterpart on a single uc-Si film, to form a complementary metal-silicon oxide-silicon (CMOS) inverter of deposited uc-Si. The uc-Si channel material can be grown at lower temperatures by plasma-enhanced chemical vapor deposition in a process similar to the deposition. The p and n channels share the same uc-Si layer. The Figure shows the processing steps of manufacturing the TFT, where (12) represents the uc-Si layer of the device.

A coated housing for exterior rearview mirrors for vehicles provides increased gloss and depth of color in appearance, and enhanced resistance to scratching, surface crazing and ultraviolet radiation degradation. The housing is preferably molded from a resinous plastic material in a predetermined color and has a generally transparent polymeric material such as clear urethane or acrylic applied in a thin coating to the unpainted housing. The generally transparent coating may include a tint or particles of metal or mica to enhance the molded housing color and/or appearance. Optionally, adhesion of the coating to the housing may be increased by mixing an adhesion promoting agent in said resinous plastic material prior to molding, or by treating the housing surface after molding and prior to application of the coating. An ultraviolet radiation absorbing, blocking, screening material may be included in the generally transparent polymeric material. A method for making the coated exterior rearview mirror housing is also disclosed.

A method of manufacturing a large-area electronic device such as a flat panel display, which method includes subjecting a semiconductor film on a polymer substrate to an energy beam treatment, e.g., for crystal growth or to anneal an ion implant, and masking the substrate prior to treatment to prevent exposure to the energy beam, wherein the adhesion of the film and other layers on the substrate is improved by first heating the substrate to pre-shrink it, and then depositing the layers on the pre-shrunk substrate at a lower temperature than the heating temperature.
