Abstract: A printing platform receives (102) (preferably in-line with a semiconductor device printing process (101)) a substrate having at least one semiconductor device printed thereon and further having a test structure printed thereon, which test structure comprises at least one printed semiconductor layer. These teachings then provide for the automatic testing (103) of the test structure with respect to at least one static (i.e., relatively unchanging) electrical characteristic metric. The static electrical characteristic metric (or metrics) of choice will likely vary with the application setting but can include, for example, a measure of electrical resistance, a measure of electrical reactance, and/or a measure of electrical continuity. Optionally (though preferably) the semiconductor device printing process itself is then adjusted (105) as a function, at least in part, of this metric.

Abstract: An apparatus having an electronic drawing surface includes a common electrode overlying a least part of the outer surface of a housing, or other object, and a bistable media layer overlying the common electrode. The bistable media layer has at least two stable states and is operable to assume a first stable state in the region of a drawing tool when an electrical voltage difference is generated between the drawing tool and the common electrode. The voltage difference produces an electrical field across a region of the bistable media layer when the drawing tool is in close proximity to the bistable layer. Optionally, an outer surface of a plurality of transparent electrodes overlies the bistable media layer.

Abstract: Organic field effect transistors (OFETs) can be created rapidly and at low cost on organic films by using a multilayer film (202) that has an electrically conducting layer (204, 206) on each side of a dielectric core. The electrically conducting layer is patterned to form gate electrodes (214), and a polymer film (223) is attached onto the gate electrode side of the multilayer dielectric film, using heat and pressure (225) or an adhesive layer (228). A source electrode and a drain electrode (236) are then fashioned on the remaining side of the multilayer dielectric film, and an organic semiconductor (247) is deposited over the source and drain electrodes, so as to fill the gap between the source and drain electrodes and touch a portion of the dielectric film to create an organic field effect transistor.

Abstract: A semiconductor device comprising organic semiconductor material (14) has one or more barrier layers (16) disposed at least partially thereabout to protect the organic semiconductor material (14) from environment-driven changes that typically lead to inoperability of a corresponding device. If desired, the barrier layer can be comprised of partially permeable material that allows some substances therethrough to thereby effect disabling of the encapsulated organic semiconductor device after a substantially predetermined period of time. Getterers (141) may also be used to protect, at least for a period of time, such organic semiconductor material.

Abstract: An apparatus (200) such as a semiconductor device comprises a gate electrode (201) and at least a first electrode (202). The first electrode preferably has an established perimeter that at least partially overlaps with respect to the gate electrode to thereby form a corresponding transistor channel. In a preferred approach the first electrode has a surface area that is reduced notwithstanding the aforementioned established perimeter. This, in turn, aids in reducing any corresponding parasitic capacitance. This reduction in surface area may be accomplished, for example, by providing openings (203) through certain portions of the first electrode.

Abstract: An energizable design image portion (203) of a provided design pattern is printed on a provided substrate (201) using a functional ink comprised of at least one energy emissive material.

In a preferred embodiment this apparatus may further comprise electrically conductive electrodes (204) on the substrate to permit selective energization of the energy emissive material to thereby induce illumination of the energizable design image portion of the design pattern.
