Zero-power modulation for resource-efficient 5G/6G messaging
A resource-efficient modulation scheme includes both conventional and zero-amplitude states.

For example, in a phase-modulation scheme such as BPSK or QPSK, a zero state represents an additional modulation state with zero transmitted amplitude. In a modulation scheme with I and Q branches in quadrature, each branch is separately amplitude modulated, plus additional states with zero amplitude in one or both branches, for different effects. For example, 16QAM with nine additional zero-amplitude states totals 25 available modulation states, resulting in 36% reduction in message size and 44% reduction in transmitted energy.

Setting method for substrate processing apparatus
A method for setting a substrate processing apparatus having a head for dispensing ink includes aligning a position of at least one vision unit, by moving the vision unit above a reference mark and taking, by the vision unit, an image of the reference mark, in which the vision unit takes an image of a substrate, and the reference mark is made on the substrate processing apparatus and fixed in one position, and aligning at least one of a movement axis of the vision unit, a position of the substrate, or a movement axis of the substrate, by moving the vision unit or the substrate in a state in which the substrate having alignment marks made thereon is located under the vision unit and taking, by the vision unit, an image of the alignment marks. |

Exhaust gas processing apparatus
There is provided an exhaust gas processing apparatus configured to cause a processing gas to be exposed to or come into contact with a liquid and thereby detoxify the processing gas. The exhaust gas processing apparatus comprises a suction casing provided with an inlet which the processing gas is sucked into and with an outlet which the processing gas is flowed out from; a liquid tank configured to receive an outlet-side part of the suction casing and store the liquid therein; and one or multiple spray nozzles placed in the liquid tank. The outlet of the suction casing is arranged to be located above a liquid surface of the liquid stored in the liquid tank. The one or multiple spray nozzles are configured to spray the liquid from around the outlet of the suction casing to a peripheral part of the outlet. |

Gas delivery system for high pressure processing chamber
A high-pressure processing system for processing a layer on a substrate includes a first chamber, a support to hold the substrate in the first chamber, a second chamber adjacent the first chamber, a foreline to remove gas from the second chamber, a vacuum processing system configured to lower a pressure within the second chamber to near vacuum, a valve assembly between the first chamber and the second chamber to isolate the pressure within the first chamber from the pressure within the second chamber, a gas delivery system configured to increase the pressure within the first chamber to at least 10 atmospheres while the first chamber is isolated from the second chamber, an exhaust system comprising an exhaust line to remove gas from the first chamber, and a common housing surrounding both the first gas delivery module and the second gas delivery module. |

Integrated circuit packages and methods of forming same
An integrated circuit package and a method of forming the same are provided. A method includes forming a conductive column over a carrier. An integrated circuit die is attached to the carrier, the integrated circuit die being disposed adjacent the conductive column. An encapsulant is formed around the conductive column and the integrated circuit die. The carrier is removed to expose a first surface of the conductive column and a second surface of the encapsulant. A polymer material is formed over the first surface and the second surface. The polymer material is cured to form an annular-shaped structure. An inner edge of the annular-shaped structure overlaps the first surface in a plan view. An outer edge of the annular-shaped structure overlaps the second surface in the plan view. |

Multilayer circuit board manufacturing method
There is provided a method of manufacturing a multilayer wiring board including: alternately stacking wiring layers and insulating layers; stacking a reinforcing sheet having openings on one surface of the resulting multilayer laminate with a soluble adhesive layer therebetween; contacting or infiltrating the soluble adhesive layer with a liquid capable of dissolving the soluble adhesive layer through the openings to thereby dissolve or soften the soluble adhesive layer; and releasing the reinforcing sheet from the multilayer laminate at the position of the soluble adhesive layer. This method enables the multilayer wiring layer to be reinforced so as to generate no large local warpage, thereby improving the reliable connection in the multilayer wiring layer and the flatness (coplanarity) on the surface of the multilayer wiring layer. The reinforcing sheet having finished its role can be released in a significantly short time, while minimizing the stress applied to the multilayer laminate. |

Device and method for bonding of substrates
A method for bonding a first substrate with a second substrate at respective contact faces of the substrates with the following steps: holding the first substrate to a first sample holder surface of a first sample holder with a holding force FH1 and holding the second substrate to a second sample holder surface of a second sample holder with a holding force FH2; contacting the contact faces at a bond initiation point and heating at least the second sample holder surface to a heating temperature TH; bonding of the first substrate with the second substrate along a bonding wave running from the bond initiation point to the side edges of the substrates, wherein the heating temperature TH is reduced at the second sample holder surface during the bonding. |

Trench etching process for photoresist line roughness improvement
A method of forming a semiconductor device structure is provided. The method includes forming a resist structure over a substrate. The resist structure includes an anti-reflective coating (ARC) layer and a photoresist layer over the ARC layer. The method further includes patterning the photoresist layer to form a trench therein. The method further includes performing a hydrogen plasma treatment to the patterned photoresist layer. The hydrogen plasma treatment is configured to smooth sidewalls of the trench without etching the ARC layer. The method further includes patterning the ARC layer using the patterned photoresist layer as a etch mask. |
