  • Publication number: 20230274957
    Abstract: The invention discloses a semiconductor multi-station processing chamber. Each of the multiple station includes a downward concave accommodation defined by walls and receives a pedestal therein. The pedestal and the walls define a first gap. A showerhead plate mounted on an upper lid above the pedestal to define a processing region. A second gap for supply swiping gas is defined between the showerhead plate and the upper lid. An isolation member is liftable between the downward concave accommodation and the showerhead plate to optionally encircle a processing region defined by the pedestal and the showerhead plate or to retract back into the downward concave accommodation. Such that, when the isolation member surrounds and encircles the processing region, the station is able to be structurally isolated from its neighboring one station.

  • Publication number: 20210393543
    Abstract: A composition for preventing or treating hypoglycemia in a patient in need thereof has a microgel that includes crosslinked polymers containing glucose-responsive moieties; and blood glucose-raising therapeutic agent loaded on or within the microgel. The microgel further includes any one or a combination of a stabilizing component and a loading-assisting component for the blood glucose- raising therapeutic agent. The polymers containing the glucose-responsive moieties form secondary crosslinks in response to low glucose level, thereby causing shrinking of the microgel and rapid release of the blood glucose-raising therapeutic agent. The composition can be used to prepare a composite microneedle patch for preventing or treating hypoglycemia, where the composition is embedded or integrated within an array of the microneedles of the microneedle patch device.
