The invention relates to an ultrasonic measuring device including an ultrasonic array configured to detect ultrasonic signals, and a housing. The housing includes an acoustic window portion and a housing wall. The ultrasonic array is arranged in the housing in acoustic contact with the acoustic window portion. The acoustic window portion is configured to adhere to a surface of the object to be examined. The invention further relates to an examination apparatus, which includes at least one such ultrasonic measuring device, and to a method for ultrasonic signal detection, in particular for ultrasound-based imaging.

Ultrasonic measuring device, examination apparatus and method for operating same

A device and method for treating the surface of a semiconductor wafer provides a treatment fluid in the form of a dispersion of gas bubbles in a treatment liquid generated at acoustic pressures less than those required to induce cavitation in the treatment liquid. A resonator supplies ultrasonic or megasonic energy to the treatment fluid and is configured to create an interference pattern in the treatment fluid comprising regions of pressure amplitude minima and maxima at an interface of the treatment fluid and the semiconductor wafer.

Ultrasonic cleaning method and apparatus

Substrates () are described for receiving a plurality of samples, especially for the preservation of biological samples at cryotemperatures comprising a plurality of substrate plates () arranged on top of one another as a stack () and comprising an anchoring axis () to which the substrate plates () are connected. Processes for the preservation of biological samples at cryotemperatures are also described.
