Abstract: A semiconductor structure includes a substrate, a channel region, a gate structure, and source/drain regions. The channel region is over the substrate. The gate structure is over the channel region, and includes a high-k dielectric layer, a tungsten layer over the high-k dielectric layer, and a fluorine-containing work function layer over the tungsten layer. The source/drain regions are at opposite sides of the channel region.

Abstract: A disposal apparatus for biosensor includes a coupling member and a capsular wrapper. The capsular wrapper includes a space having a closed end and an open end to hold a biosensor. The coupling member has a coupling portion connecting to the closed end and a test strip adapter with two ends respectively formed a test strip insertion end and a test strip extended slot. The test strip insertion end passes through the slot and inserts into a test strip loading port of the biosensor. The capsular wrapper encases the biosensor to allow the test strip insertion end to insert into the test strip loading port. Through coupling of the test strip adapter, the biosensor can perform testing. After the testing is finished, the coupling member and the test strip can be wrapped together by the capsular wrapper and be discarded, thus avoiding user being contaminating with samples on the test strip.
