Abstract: A semiconductor structure is provided. The semiconductor structure includes a substrate, a channel layer, a barrier layer, a compound semiconductor layer, a gate electrode, and a stack of dielectric layers. The channel layer is disposed on the substrate. The barrier layer is disposed on the channel layer. The compound semiconductor layer is disposed on the barrier layer. The gate electrode is disposed on the compound semiconductor layer. The stack of dielectric layers is disposed on the gate electrode. The stack of dielectric layers includes layers having different etching rates.

Abstract: A quick lift assembling storage box includes a folding box in a flat half-folded state, and a traction support board disposed at the top of the folding box. After a user lifts the traction support board to drive and change the folding box in the flat half-folded state into a three-dimensional state with an accommodation space, and then the user can press and superimpose the traction support board onto the bottom and the inner sides of the folding box to reinforce the strength of the folding box.

Abstract: A quick-assembly containing box formed by folding a cardboard includes a bottom board, left- and right-side boards extending from the periphery of the bottom board, and front- and rear-side boards folded inwardly onto the bottom board to define a half-folded state. When the left- and right-side boards are pushed from the outside to the inside and erected, four positioning pieces already folded and adhered to the left- and right-side boards can push the front- and rear-side boards in a forward direction to erect, so as to achieve the effect of assembling the containing box of a three-dimensional state quickly.

Abstract: A folding box has a foldable positioning piece extending from an outer edge of each of front and rear panels thereof. A first reinforcement sheet is attached and connected to the positioning piece, thereby reinforcing the strength of the front and rear panels and side panels of the folding box. By the extension of the reinforcement sheets, the structural stability of the folding box can be maintained when the folding box is produced with the thin cardboard and the area required for the preparation of the cardboard is reduced.
