Patent number: 9733574Abstract: Manufacturing of semiconductor devices often involves performed photolithography to pattern and etch the various features of those devices. Such photolithography involves masking and focusing light onto a surface of the semiconductor device for exposing and etching the features of the semiconductor devices. However, due to design specifications and other causes, the semiconductor devices may not have a perfectly flat light-incident surface. Rather, some areas of the semiconductor device may be raised or lowered relative to other areas of the semiconductor device. Therefore, focusing the light on one area causes another to become unfocused. By carefully designing a photomask to cause phase shifts of the light transmitted therethrough, focus across all areas of the semiconductor device can be achieved during photolithography, which results in sharp and accurate patterns formed on the semiconductor device.Type: GrantFiled: October 17, 2013Date of Patent: August 15, 2017Assignee: Cypress Semiconductor CorporationInventors: Gong Chen, Frank Tsai

Patent number: 9500952Abstract: An orthogonal process for photolithographic patterning organic structures is disclosed. The disclosed process utilizes fluorinated solvents or supercritical CO2 as the solvent so that the performance of the organic conductors and semiconductors would not be adversely affected by other aggressive solvent. One disclosed method may also utilize a fluorinated photoresist together with the HFE solvent, but other fluorinated solvents can be used. In one embodiment, the fluorinated photoresist is a resorcinarene, but various fluorinated polymer photoresists and fluorinated molecular glass photoresists can be used as well. For example, a copolymer perfluorodecyl methacrylate (FDMA) and 2-nitrobenzyl methacrylate (NBMA) is a suitable orthogonal fluorinated photoresist for use with fluorinated solvents and supercritical carbon dioxide in a photolithography process.Type: GrantFiled: December 11, 2015Date of Patent: November 22, 2016Assignee: Cornell UniversityInventors: Christopher K. Ober, George Malliaras, Jin-Kyun Lee, Alexander Zakhidov, Margarita Chatzichristidi, Priscilla Dodson

Patent number: 9451704Abstract: A plurality of suspension boards and an inspection substrate are integrally supported by a support frame. In each suspension board, a line is formed on a conductive first support substrate via a first insulating layer. The first support substrate and the line are electrically connected by a first via in the first insulating layer.

Patent number: 9400953Abstract: Methods, algorithms, processes, circuits, and/or structures for laser patterning suitable for customized RFID designs are disclosed. In one embodiment, a method of laser patterning of an identification device can include the steps of: (i) depositing a patternable resist formulation on a substrate having configurable elements and/or materials thereon; (ii) irradiating the resist formulation with a laser tool sufficiently to change the solubility characteristics of the resist in a developer; and (iii) developing exposed areas of the resist using the developer. Embodiments of the present invention can advantageously provide a relatively low cost and high throughput approach for customized RFID devices.Type: GrantFiled: May 22, 2014Date of Patent: July 26, 2016Assignee: Thin Film Electronics ASAInventors: Criswell Choi, Joerg Rockenberger, Christopher Gudeman, J.

Patent number: 9396958Abstract: Techniques herein provide methods for self-aligned etching that use existing features for patterning or registering a pattern, without damaging existing features. Existing substrate structures are used to create a surface that enables directed self-assembly (DSA) of block copolymers (BCP) without a separate lithographic patterning layer. Methods herein include recessing at least one existing material or structure on a substrate, and adding a film that remains on the recessed material only. This film can be selected to have a preferential surface energy that enables controlled self-assembly of block copolymers. The substrate can then be etched using both existing structures and one polymer material as an etching mask. One example advantage is that self-assembled polymer material can be located to protect exposed corners of existing features, which reduces a burden of selective etch chemistry, increases precision of subsequent etching, and reduces sputter yield.Type: GrantFiled: September 25, 2015Date of Patent: July 19, 2016Assignee: Tokyo Electron LimitedInventors: Andrew W. Metz, Anton J. deVilliers
