Abstract:
A vertical channel field-effect transistor is taught. The vertical channel field-effect transistor comprises a primary substrate (510) and a secondary substrate. A bottom conducting layer (520) is provided on the primary substrate. A top conducting layer (530) is transferred from a secondary substrate to the primary substrate by using an insulating adhesive layer (570). The thickness of the insulating adhesive layer defines the channel length. The portion of the top conducting layer which is over the bottom conducting layer defines the maximum possible channel. At least one semiconducting layer (540) is provided on and around a perimeter of at least a portion of the channel width. At least one insulating layer (550) is provided on at least a portion of the at least one semiconducting layer. At least one gate conducting layer (560) provided on at least a portion of the at least one insulating layer.
Abstract:
Ein Verfahren zur Herstellung einer organischen, halbleitenden Folie umfassend die folgenden Schritte: Aufbringen (103) eines Films (230) aus einem organischen Material auf ein Trägersubstrat (200) mit einer Opferschicht z.B. ein wasserlöslicher Film (220) und Bestrahlung der Oberfläche (233) des Films (230) zur Bildung einer vernetzten Schicht (237). Die Folie kann in einem elektronischen Bauelement (300, 350) verwendet werden.

Abstract:
Peelable polymeric film, in particular, peelable polymeric film which comprises a polymeric substrate layer and a coating layer of adhesive, and which is of particular use in the manufacture of electronic devices is described. The adhesive layer is derived from an aqueous composition which comprises an aliphatic polyurethane and is switchable.
Abstract:
Transfer films, articles made therewith, and methods of making and using transfer films to form an electrical stack are disclosed. The transfer films (100) may include a plurality of co-extensive electrical protolayers (22, 23, 24) forming an electrical protolayer stack (20), at least selected or each electrical protolayer independently comprising at least 25 wt% sacrificial material and a thermally stable material and having a uniform thickness of less than 25 micrometers. The transfer films may include a plurality of co-extensive electrical protolayers forming an electrical protolayer stack, at least selected or each protolayer independently exhibiting a complex viscosity of between 103and 104Poise at a shear rate of 100/s when heated to a temperature between its Tg and Tdec.
