A semiconductor wafer metrology technique comprising performing atmospheric buoyancy compensated weighing of a wafer, in which the wafer is weighed in a substantially upright condition. A vertical or near vertical wafer orientation causes the surface area in the direction of a force (weight) sensor to be reduced compared with a horizontal wafer orientation. Hence, the electrostatic force components acting in the same direction as the wafer weight force component is reduced.

The invention provides a manufacturing method of a water-repellent flame-retardant hook-and-loop fastener. The manufacturing method comprises the following specific steps of weaving a nylon hook-and-loop fastener according to the arrangement rule that one silver-plated nylon bottom yarn is arranged every 6-9 common nylon bottom yarns; cleaning the hook-and-loop fastener; sequentially performing flame-retardant finishing and water-repellent finishing on the nylon hook-and-loop fastener; performing resin finishing on the nylon hook-and-loop fastener; performing anti-static finishing on the nylonhook-and-loop fastener subjected to resin finishing; and dehydrating the nylon hook-and-loop fastener in a dehydrator. When the hook-and-loop fastener prepared by the method is used in an extreme environment, the electrostatic effect is reduced by a metal net formed by the silver-plated bottom yarns and the fine titanium dioxide added in resin finishing. In addition, an antistatic agent is used for finishing, so that static electricity generation is reduced, static electricity dissipation is accelerated, the static effect is reduced, and the fabric is suitable for flammable and combustible environments. Through flame-retardant finishing and water-repellent finishing, the flame-retardant performance and the water-repellent performance of the fabric are improved respectively, so that the fabric is suitable for high-temperature, high-humidity or soaking environments.

The invention belongs to the technical field of dyeing and finishing technology. In order to eliminate static electricity on the surface of the fabric in the carbon sanding process of the existing fabric, a tentering process of an anti-static auxiliary needs to be added. However, the anti-static auxiliary will make the fabric feel soft. In order to achieve the same sanding effect, the tension of the sanding and the time for sanding are needed to increase, which will increase the probability of contamination of the variegated wool. Therefore, it is necessary to add an air-softening and hair-removing process of an anti-pilling machine, which significantly increases processing cost. In view of the above problems, the invention provides a method for improving surface electrostatic properties of carbon sanded fabrics. Alcohol-ether surfactants are added during the soaping process of the fabric after dyeing, the tentering process of the anti-static auxiliary before the sanding and the air-softening and hair-removing process after the sanding are eliminated, and the time of sanding is reduced at the same time. The method reduces the electrostatic effect of the fabric without increasing washing, and reduces the processing cost.
