Abstract: A multi-spray RRC process with dynamic control to improve final yield and further reduce resist cost is disclosed. In one embodiment, a method, includes: dispensing a first layer of solvent on a semiconductor substrate while spinning at a first speed for a first time period; dispensing the solvent on the semiconductor substrate while spinning at a second speed for a second time period so as to transform the first layer to a second layer of the solvent; dispensing the solvent on the semiconductor substrate while spinning at a third speed for a third time period so as to transform the second layer to a third layer of the solvent; dispensing the solvent on the semiconductor substrate while spinning at a fourth speed for a fourth time period so as to transform the third layer to a fourth layer of the solvent; and dispensing a first layer of photoresist on the fourth layer of the solvent while spinning at a fifth speed for a fifth period of time.

Abstract: A backlit-module-embedded illuminated keyswitch structure includes a baseplate, a mask film disposed below the baseplate and having a first coating configured to substantially reflect a light, a light guide sheet disposed at one side of the mask film and having a light source hole, a reflective layer disposed at one side of the light guide sheet opposite to the mask film and having an opening communicating with the light source hole, a top glue configured to connect the mask film and the light guide sheet around the light source hole, and a bottom glue configured to connect the light guide sheet and the reflective layer around the light source hole. The first coating covers the light source hole. In a stacked direction of the mask film, the light guide sheet, and the reflective layer, at least one of the top glue and the bottom glue overlaps the first coating.

Abstract: Disclosed herein are albumin compositions having defined fatty acid profiles and methods of using the same. The albumin compositions described herein are suitable for use in cell culture methods, protein stabilization methods, amongst others. The albumin compositions described herein may improve the viability of and/or promote the growth of cells (e.g., mammalian cells) when the cells are cultured in a medium containing the albumin compositions. The albumin compositions described herein may improve the stability of a biologic when the biologic is in the presence of the albumin compositions. Further provided herein are methods of formulating albumin compositions having defined fatty acid profiles as described herein.

Abstract: Methods and compositions of altering a eukaryotic cell are described including providing to the eukaryotic cell a guide DNA sequence complementary to a target nucleic acid sequence, providing to the eukaryotic cell an Ago enzyme or a nuclease null Ago protein that interacts with the guide DNA sequence for DNA-guided gene editing and regulation of the target nucleic acid sequence in a site specific manner.

Abstract: A method of making a polypeptide including one or more D-amino acids is provided. The method includes combining a ribosome with protein translation factors including (1) a template encoding the polypeptide, wherein the template encoding the polypeptide includes one or more codons which have been recoded to accept a tRNA attached to a D-amino acid, (2) a plurality of L-amino acids and a plurality of corresponding tRNAs, (3) a plurality of D-amino acids and their corresponding aminoacyl tRNA synthetase or a plurality of tRNAs ligated with a D-amino acid, and (4) elongation factor P in a concentration of 2 to 20 micromolar, wherein translation of the template encoding the polypeptide occurs to produce the polypeptide including one or more D-amino acids.

Abstract: In some embodiments, a probe card includes a PCB, a substrate, a pair of probes, a capacitive device and a first part. The PCB includes a pair of conductive paths through a first surface and a second surface of the PCB. The substrate includes a pair of conductive paths through a first surface and a second surface of the substrate. The conductive paths of the substrate and the corresponding conductive paths of the PCB are coupled between the first surface of the substrate and the second surface of the PCB. The probes and the corresponding conductive paths of the substrate are coupled beyond the second surface of the substrate. The capacitive device is coupled between a first conductive path and a second conductive path through the PCB, the substrate and the probes. The first part is configured beyond the second surface of the PCB, and holds the capacitive device.

Abstract: Among other things, one or more techniques and/or systems are provided for shielding a signal pin. A signal pin, such as a signal pin within a probe card used to test electronic devices, such as integrated circuits, is shielded from interference signals, which are emitted from other signal pins within the probe card. Shielding the signal pin mitigates cross-talk issues and/or impendence control issues associated with signals that are carried by the signal pin. In one example, one or more shield pins are arranged with respect to the signal pin according to a shield configuration. For example, the shield configuration comprises a plane of signal pins, a substantially regular layout of signal pins, or a polygonal layout of signal pins, etc. In this way, one or more shield pins inhibit unintended interactions or effects that otherwise occur among two or more signal pins.

Abstract: Some embodiments relate to an integrated circuit. The integrated circuit includes an inductive or capacitive wireless communication structure located on a die region of the integrated circuit. This wireless communication structure is configured to wirelessly receive a test stimulus vector to test circuitry on the die region. The integrated circuit also includes a landing region having a size and location suitable to allow a conductive needle or conductive probe to come into direct physical and electrical contact with the landing region. The landing region provides a DC power supply to the circuitry on the die region while the test stimulus vector is wirelessly received.
