A semiconductor structure and a method for forming the same, wherein the structure comprises: a substrate; a gate structure and a plurality of source / drain doping layers, the gate structure is located on the substrate, and the source / drain doping layers are located in the substrate on both sides of the gate structure; a first conductive structure and a second conductive structure, the first conductive structure is located on the source / drain doping layers, and the second conductive structure is located on the gate structure; a first filling opening which exposes the side wall of the first conductive structure and the gate structure; a first filling layer located in the first filling opening, and the first filling layer has a first air gap therein. Since there is no other filling material between the first conductive structure and the gate structure, the first filling layer has a larger filling space, and the cavity of the first air gap in the first filling layer is larger. When the cavity of the first air gap is larger, the dielectric constant between the first conductive structure and the gate structure is smaller, and the parasitic capacitance between the first conductive structure and the gate structure is smaller, so that the performance of the semiconductor structure finally formed is better.

The double-circulation perlite ore sand gradient preheating system utilizing the waste heat of the tail gas of the fuel gas expansion furnace is provided with the double-return-stroke channels, the material heating time is prolonged, the heating temperatures of the double-return-stroke channels are different, low-temperature preheating is conducted firstly, then medium-temperature preheating is conducted, and the heating efficiency is improved. And most free water and part of bound water in the ore sand are removed more slowly and mildly. According to the technical scheme, an outer-layer material channel is formed between an outer pipe and a middle pipe, and a first spiral conveying structure is arranged on the inner wall of the outer-layer material channel; an inner-layer material channel is formed between the middle pipe and the inner core pipe, and a second spiral conveying structure is arranged on the inner wall of the inner-layer material channel; the heating cavity consists of an inner cavity of the inner core tube; and the rotating direction of the first spiral conveying structure is opposite to that of the second spiral conveying structure, so that materials are conveyed from the first end to the second end in the outer-layer material channel, enter the inner-layer material channel from the second feeding hole in the second end and are conveyed from the second end to the first end in the inner-layer material channel.
