2 results about "Partial thickness" patented technology

A semiconductor structure and a method of forming the same, the method comprising: providing a substrate including a substrate and a fin material layer; etching a partial thickness of the fin material layer to form an initial fin, and the etching has a first etch rate ratio; etching a remaining fin material layer exposed by the initial fin to form a fin standing on the substrate, the fin including a bottom fin, a first portion fin and a second portion fin from bottom to top, the second portion fin and the first portion fin constituting an effective fin, and the etching the partial thickness of the fin material layer exposed by the initial fin has a second etch rate ratio, the second etch rate ratio is less than the first etch rate ratio, for making a bottom line width of the first portion fin less than a top line width of the first portion fin; forming an isolation layer covering a sidewall of the bottom fin and exposing the effective fin. The present application reduces leakage current and reduces the impact on the on-current, thereby improving the on-off current ratio of the transistor.

The utility model discloses a nursing special rehabilitation seat cushion after operation relates to rehabilitation seat cushion technical field, including bottom plate, the top fixedly connected with soft pad of bottom plate, the both sides in soft pad are all embedded with water box, and one side wall of two water boxes all is fixedly connected with water pipe, and fixedly connected with a plurality of arc conduits between two water pipes, and one side wall of one water box is installed with micro water pump, the utility model discloses nursing special rehabilitation seat cushion after operation, through setting bottom plate and soft pad, and the partial thickness of soft pad is thicker, can reduce the extrusion of hip when sitting with the help of soft pad, to reduce the extrusion of wound when sitting, the arc backrest of quick assembly that can be equipped is formed with the support to the back of user, reduces the extrusion of wound when sitting and the physical strength that needs when sitting personally, and the heating sheet that is equipped with on arc backrest can heat hot compress to waist and sacrum of user when leaning, and the eight acupoints of waist and sacrum are hot compressed, can promote the blood circulation of waist.
