Publication number: 20190091636Abstract: The subject of the invention is new membranes in which tailor-made membrane transport proteins (such as e.g. TCDB classified proteins) act as pore-forming proteins (e.g. FhuA) or peptides which act as pores in the membrane. The membranes can preferably be produced both by linking synthesised protein-polymer conjugates and by direct linking of the pore-forming proteins and peptides. Such membranes are distinguished by many outstanding features which existing membranes have not been able to offer to date.Type: ApplicationFiled: March 1, 2017Publication date: March 28, 2019Applicants: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V., RHEINISCH-WESTFÄLISCHE TECHNISCHE HOCHSCHULE (RWTH) AACHENInventors: Himanshu CHARAN, Ulrich GLEBE, Alexander BÖKER, Murat TUTUS, Ulrich SCHWANEBERG, Leilei ZHU, Marco BOCOLA, Tayebeh MIRZAEIGARAKANI, Julia KINZEL, Deepak ANAND

Publication number: 20160282282Abstract: A lithographic manufacturing system produces periodic structures with feature sizes less than 10 nm and a direction of periodicity (D). A beam of radiation (1904) having a range of wavelengths in the EUV spectrum (1-100 nm or 1-150 nm) is focused into a spot (S) of around 5 ?m diameter. Reflected radiation (1908) is broken into a spectrum (1910) which is captured (1913) to obtain a target spectrum signal (ST). A reference spectrum is detected (1914) to obtain a reference spectrum signal (SR). Optionally a detector (1950) is provided to obtain a further spectrum signal (SF) using radiation diffracted at first order by the grating structure of the target. The angle of incidence (?) and azimuthal angle (?) are adjustable. The signals (ST, SR, SF) obtained at one or more angles are used to calculate measured properties of the target, for example CD and overlay.Type: ApplicationFiled: March 24, 2016Publication date: September 29, 2016Applicants: ASML Netherlands B.V., RWTH Aachen UniversityInventors: Richard QUINTANILHA, Serhiy DANYLYUK

Patent number: 9443589Abstract: A method for reading out a non-volatile memory element having at least two stable states 0 and 1. This memory element comprises at least one resistive memory cell, which encodes the two states 0 and 1 into a state HRS having higher electrical resistance and a state LRS having lower electrical resistance. In the two states 0 and 1, the memory element has differing capacitances C0,1; this difference is used to determine which state is present. A memory element is selected in which a fixed capacitance that is independent of the state of the memory cell is connected in series with the memory cell. A series connection of a resistive memory cell with a fixed capacitance, instead of with a second resistive memory cell, improves the signal strength during capacitive read-out. The second memory cell becomes indispensable for the memory function when the memory element is read out capacitively.Type: GrantFiled: May 17, 2014Date of Patent: September 13, 2016Assignees: Forschungszentrum Juelich GmbH, Rheinisch-Westfaelische Technisque Hochschule (RWTH) AachenInventors: Stefan Tappertzhofen, Eike Linn, Lutz Nielen, Rainer Waser, Ilia Valov

Patent number: 9347974Abstract: The application relates to a method for determining beam parameters of a charge carrier beam, a measuring device, and a charge carrier beam device. The charge carrier beam (4) from a charge carrier beam device (1) is guided, by means of a beam deflection unit (3), over a slit aperture arrangement which is provided in an aperture device (7) and which has one or more slit apertures (8). Measurement plane coordinates of the beam components that penetrate the slit aperture arrangement are determined. On the basis of the measurement plane coordinates, the aperture device automatically moves in such a way that a measuring aperture (9) arranged in the aperture device moves over a predefined measurement reference point. The beam parameter is measured by the measuring aperture. In a measuring device (5) suitable for carrying out said method, the slit aperture arrangement has at least two non-parallel slit aperture sections (12, 13, 15, 16) which can be part of a single continuous slit aperture.Type: GrantFiled: March 11, 2013Date of Patent: May 24, 2016Assignees: RWTH AACHEN KOERPERSCHAFT DES OEFFENTLICHEN RECHTS, AIXACCT SYSTEMS GmbHInventors: Uwe Reisgen, Jens De Vries, Alexander Backhaus, Hans-Peter Bauer, Sebastian Ufer, Bernd Reichenberg, Thorsten Schmitz-Kempen
