Abstract: Integrated circuit structures, arrangements, and manufacturing processes are discussed herein. In one example, a method of forming a transistor structure includes forming a dielectric layer onto a gate element and forming a corrugated surface into the dielectric layer using at least an atomic layer etching (ALE) process to remove portions of the dielectric layer. The method also includes forming a semiconductor layer onto the corrugated surface and forming a source element and a drain element onto the semiconductor layer.

Abstract: Provided is a manufacturing process for electronic circuit components such as bare dies, and packaged integrated chips, among other configurations, to form electronic assemblies. The surface of the electronic circuit component carries electronic elements such as conductive traces and/or other configurations including contact pads. A method for forming an electronic assembly includes providing a tacky layer. Then an electronic circuit component is provided having a first side and a second side, where the first side carries the electronic elements. The first side of the electronic circuit component is positioned into contact with the tacky layer. A bonding material is then deposited to a portion of the adhesive layer that is not covered by the first side of the electronic circuit component, to a depth which is sufficient to cover at least a portion of the electronic circuit component. The bonding material is then fixed or cured into a fixed or cured bonding material, and the tacky layer is removed.

Abstract: A method and system utilizes ink jetting or printing of surface work function modification material or solution to form modified p-type and/or n-type electrodes. The proposed method is suitable for making complementary OTFT circuits in roll-to-roll fabrication environment.

Abstract: A stress-engineered frangible structure includes multiple discrete glass members interconnected by inter-structure bonds to form a complex structural shape. Each glass member includes strengthened (i.e., by way of stress-engineering) glass material portions that are configured to transmit propagating fracture forces throughout the glass member. Each inter-structure bond includes a bonding member (e.g., glass-frit or adhesive) connected to weaker (e.g., untreated, unstrengthened, etched, or thinner) glass member region(s) disposed on one or both interconnected glass members that function to reliably transfer propagating fracture forces from one glass member to other glass member. An optional trigger mechanism generates an initial fracture force in a first (most-upstream) glass member, and the resulting propagating fracture forces are transferred by way of inter-structure bonds to all downstream glass members.

Abstract: A transient electronic device utilizes a glass-based interposer that is treated using ion-exchange processing to increase its fragility, and includes a trigger device operably mounted on a surface thereof. An integrated circuit (IC) die is then bonded to the interposer, and the interposer is mounted to a package structure where it serves, under normal operating conditions, to operably connect the IC die to the package I/O pins/balls. During a transient event (e.g., when unauthorized tampering is detected), a trigger signal is transmitted to the trigger device, causing the trigger device to generate an initial fracture force that is applied onto the glass-based interposer substrate. The interposer is configured such that the initial fracture force propagates through the glass-based interposer substrate with sufficient energy to both entirely powderize the interposer, and to transfer to the IC die, whereby the IC die also powderizes (i.e., visually disappears).

An electronic circuit component which has conductive circuit tracings, and is located within the at least one opening of the substrate. An alignment area where a first surface of the substrate and a first surface of the electronic circuit component are aligned in a substantially planar flat relationship with the electronic circuit component.

Abstract: A stressed substrate for transient electronic systems (i.e., electronic systems that visually disappear when triggered to do so) that includes one or more stress-engineered layers that store potential energy in the form of a significant internal stress. An associated trigger mechanism is also provided that, when triggered, causes an initial fracture in the stressed substrate, whereby the fracture energy nearly instantaneously travels throughout the stressed substrate, causing the stressed substrate to shatter into multiple small (e.g., micron-sized) pieces that are difficult to detect. The internal stress is incorporated into the stressed substrate through strategies similar to glass tempering (for example through heat or chemical treatment), or by depositing thin-film layers with large amounts of stress. Patterned fracture features are optionally provided to control the final fractured particle size. Electronic systems built on the substrate are entirely destroyed and dispersed during the transience event.
