    摘要: A method of sensing a biological sample includes introducing a fluid containing the biological sample through a first opening in a substrate. The method further includes passing the fluid from the first opening to a first cavity through at least one microfluidic channel. The method further includes repelling the biological sample from a first surface of the first cavity using a first surface modification layer. The method further includes attracting the biological sample to a sensing device using a plurality of modified surface patterns, wherein a first modified surface pattern of the plurality of modified surface patterns has different surface properties from a second modified surface pattern of the plurality of modified surface patterns. The method further includes outputting the fluid through a second opening in the substrate.

    摘要: The present disclosure provides a bio-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 substrate, a transistor structure having a treated layer adjacent to the channel region, an isolation layer, and a dielectric layer in an opening of the isolation layer on the treated layer. The dielectric layer and the treated layer are disposed on opposite side of the transistor from a gate structure. The treated layer may be a lightly doped channel layer or a depleted layer.

    摘要: 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.
