  • Patent number: 11225080
    Abstract: The present invention provides a method for forming a thermal inkjet printhead, comprising at least the following steps: providing a semiconductor wafer including an integrated electronic circuit and a section for forming a thermal actuator element, the integrated circuit comprising at least: a thermal insulating layer formed over a substrate; and a first metal layer formed over the thermal insulating layer; wherein the first metal layer extends into the section for forming the thermal actuator element; and etching a section for forming a thermal actuator element to the first metal layer such that the first metal layer is acting as an etch stop layer. Further there is provided a thermal inkjet printhead formed by a method of the present invention and a semiconductor wafer for forming the thermal inkjet printheads by a method of the present invention.

  • Patent number: 10308869
    Abstract: The present invention relates to markers for liquids that can be used to authenticate the origin and genuineness of a liquid, preferably a bulk liquid such as fuel. For this purpose, the present invention teaches the use of a polymer capable of forming a semiconducting polymer particle (pdot) in the liquid in small amounts. The invention encompasses a liquid comprising a) a polymer that is capable of forming a semiconducting polymer particle (pdot), the concentration of the polymer being 10 ppm by weight or less, and b) an organic substance in an amount of 90% by weight or more. The invention furthermore envisages the use of such a polymer as an authenticating marker in a liquid, preferably a fuel, and a method for authenticating the genuineness and/or origin of a liquid comprising a polymer capable of forming a semiconducting polymer particle (pdot), comprising the steps i. concentrating, isolating and/or extracting the polymer capable of forming a semiconducting polymer particle (pdot); ii.

  • Patent number: 7255799
    Abstract: On a die that has etchings on a surface, firstly a sheet of negative photoresist is laid down which, by means of an exposure and subsequent development, is left only above the etchings; then, upon the negative photoresist, a positive photoresist is applied, which is subjected to exposure and development to produce functional geometries deposited in thin film; subsequently the positive photoresist is removed in a “lift-off” operation, and the negative photoresist is taken off in a plasma operation, thus revealing the etchings.
