  • Patent number: 10103108
    Abstract: A nanostructured chip includes a substrate and a nanostructured layer, wherein the substrate has a first surface and a second surface on which the nanostructured layer is formed. A method of producing the nanostructured chip includes the step of forming the nanostructured layer on the second surface of the substrate. Whereby, the nanostructured layer effectively disperses a stress to increase the flexural strength of the nanostructured chip. Therefore, during the subsequent procedures to form an epitaxial layer on the first surface, the nanostructured layer is helpful to prevent the epitaxial layer from generating cracks, and prevent the substrate from bowings, or fragments.

  • Patent number: 9689865
    Abstract: The present invention provides a personal hygiene item. In simple terms, one of the main features of the present invention is to provide a low-cost personal hygiene item capable of providing a multi-component detection function. The personal hygiene item of the present invention mainly comprises a first material layer and a second material layer. The first material layer is made of hydrophobic material, and the second material layer is disposed thereon. Also, the second material layer comprises a discolored portion. In actual practice, a fluid under test contacts with the corresponding discolored portions via the hydrophobic layer of second material layer for a color changing reaction. Meanwhile, since the hydrophilic performance of the discolored portion is better than the hydrophilic performance of the hydrophilic layer, the back permeation of the fluid under test can herein be prevented.
