Methods, computer program products, and apparatuses for reducing sticking during a lithography process are disclosed. An exemplary method of reducing sticking of an object to a modified surface that is used to support the object in a lithography process can include controlling a light source to deliver light to a native surface thereby causing ablation of at least a portion of the native surface to increase the roughness of the native surface thereby forming the modified surface. The increased roughness reduces the ability of the object to stick to the modified surface.

Provided is a method for manufacturing a board with a roughened surface and a method for manufacturing a board having a plated layer that allow easily manufacturing the board having a plated layer. One of embodiments is a method for manufacturing a board with a surface roughened for wiring formation. The method for manufacturing a board includes performing laser ablation on a board containing a resin at least on a surface of the board. A laser light irradiated in the laser ablation is a laser light having a pulse width of 1 ps or less, a wavelength of 320 nm or more, and an output of 1 W or less.

Electrostatic chucks (ESCs) for reactor or plasma processing chambers, and methods of fabricating ESCs, are described. In an example, a method of fabricating a substrate support assembly includes providing a ceramic top plate having a top surface with a processing region. A plurality of mesas is formed within the processing region and on the top surface of the ceramic plate. Laser-machining of one or more of the plurality of mesas is performed to reduce or to increase a surface roughness of the one or more of the plurality of mesas.

An earth-boring tool having at least one cutting element with a multi-friction cutting face provides for the steering of formation cuttings as the cuttings slide across the cutting face. The multi-friction cutting element includes a diamond table bonded to a substrate of superabrasive material. The diamond table has a cutting face formed thereon with a cutting edge extending along a periphery of the cutting face. The cutting face has a first area having an average surface finish roughness less than an average surface finish roughness of a second area of the cutting face, the two areas separated by a boundary having a proximal end proximate a tool crown and a distal end remote from the tool crown.

A resin molded article that has a high bond strength in a composite molded article in which a first molded article and a second molded article are integrated, and that has a stable and uniform bond strength of a composite molded article between shots of the molded article. The composite molded article includes a grooved first resin molded article containing at least a resin, a glass fiber, and a laser absorption material, and having grooves that expose the glass fiber; and a second molded article adjacently disposed on the grooved surface of the first resin molded article. In the first resin molded article, the glass fiber is added in an amount of 12-45 mass % with respect to the total mass of the resin composition that constitutes the resin molded article, the laser absorption material is added in an amount of 0.25-10 mass % with respect to the total mass of the resin composition, and the glass fiber and the laser absorption material are blended within specific blending ranges.

A method of preparing antimicrobial surface on medical devices: first, producing multi-functional surface with bacterial anti-adhesion and self-cleaning functions through single-stop ultrafast laser fabrication approach for development of micro/nano patterns, then producing bactericidal thin film through depositing metal nanoparticles on those micro/nano patterned surfaces. The combination of bacterial anti-adhesion and bactericidal film can inhibit initial bacterial adhesion and release heavy metal ions to kill the bacteria simultaneously. Meanwhile, the multi-functional surface with self-cleaning function can prevent the killed bacteria from accumulating at the substrate surface, thereby obtaining long-lasting antibacterial effect.

A pulley assembly having a body, a shaft mount and a plurality of bolts is disclosed. The body is aligned to the shaft mount by providing a tight tolerance between a shoulder portion of the bolt and a neck portion of a counter sunk hole formed in the body. Additionally, an outer surface of the body may have a pattern of friction lines or patches formed by fusing particulate matter to the outer surface with heat generated by a laser beam.

Provided are a joint component formed with fine recessed portions, a multiplate clutch device including the joint component, and a joint component manufacturing method. At the joint component, many fine recessed portions are formed at a joint surface joined to a joint object. The joint surface is formed in a circular ring shape along a peripheral direction of the base body, and is formed with a flatness of equal to or less than 0.15 mm. The fine recessed portions are formed at the joint surface such that adjacent ones of the fine recessed portions do not overlap with each other and a formation density per unit area at the joint surface is uniform. The fine recessed portions are formed as laser processing marks formed at the base body by irradiation with laser light.

A firearm having a laser induced friction surface. A method for forming the laser induced friction surface on the firearm may includes the steps of disposing the laser machine adjacent to a component of the firearm, adjusting the laser machine, then applying the laser beam of the laser machine onto a component surface.
