  • Patent number: 8846416
    Abstract: The present disclosure provides biochips and methods of fabricating biochips. The method includes combining three portions: a transparent substrate, a first substrate with microfluidic channels therein, and a second substrate. Through-holes for inlet and outlet are formed in the transparent substrate or the second substrate. Various non-organic landings with support medium for bio-materials to attach are formed on the first substrate and the second substrate before they are combined. In other embodiments, the microfluidic channel is formed of an adhesion layer between a transparent substrate and a second substrate with landings on the substrates.

  • Publication number: 20140252421
    Abstract: The present disclosure provides a bio-field effect transistor (BioFET) device and methods of fabricating a BioFET and a BioFET device. The method includes forming a BioFET using one or more process steps compatible with or typical to a complementary metal-oxide-semiconductor (CMOS) process. The BioFET device includes a gate structure disposed on a first surface of a substrate and an interface layer formed on a second surface of the substrate. The substrate is thinned from the second surface to expose a channel region before forming the interface layer.

  • Publication number: 20140073039
    Abstract: The present disclosure provides a biological field effect transistor (BioFET) and a method of fabricating a BioFET device. The method includes forming a BioFET using one or more process steps compatible with or typical to a complementary metal-oxide-semiconductor (CMOS) process. The BioFET device includes a plurality of micro wells having a sensing gate bottom and a number of stacked well portions. A bottom surface area of a well portion is different from a top surface area of a well portion directly below. The micro wells are formed by multiple etching operations through different materials, including a sacrificial plug, to expose the sensing gate without plasma induced damage.

  • Publication number: 20130256259
    Abstract: A method of forming of MEMS nanostructures includes a portion of a substrate is recessed to form a plurality of mesas in the substrate. Each of the plurality of mesas has a top surface and a sidewall surface. A light reflecting layer is deposited over the substrate thereby covering the top surface and the sidewall surface of each mesa. A protection layer is formed over the light reflecting layer. An ARC layer is formed over the protection layer. An opening in a photo resist layer is formed over the ARC layer over each mesa. A portion of the ARC layer, the protection layer and the light reflecting layer are removed through the opening to expose the top surface of each mesa. The photo resist layer and the ARC layer over the top surface of each mesa are removed.
