摘要： A SiGe HBT has an inverted heterojunction structure, where the emitter layer is formed prior to the base layer and the collector layer. The frequency performance of the SiGe HBT is significantly improved through a better thermal process budget for the base profile, essential for higher cut-off frequency (fT) and a minimal collector-base area for a reduced parasitic capacitance, essential for higher maximum oscillation frequency (fmax). This inverted heterojunction structure can be fabricated by using ALE processes to form an emitter on a preformed epitaxial silicide, a base over the emitter and a collector over the base.

摘要： A metal silicide thin film and ultra-shallow junctions and methods of making are disclosed. In the present disclosure, by using a metal and semiconductor dopant mixture as a target, a mixture film is formed on a semiconductor substrate using a physical vapor deposition (PVD) process. The mixture film is removed afterwards by wet etching, which is followed by annealing to form metal silicide thin film and ultra-shallow junctions. Because the metal and semiconductor dopant mixture is used as a target to deposit the mixture film, and the mixture film is removed by wet etching before annealing, self-limiting, ultra-thin, and uniform metal silicide film and ultra-shallow junctions are formed concurrently in semiconductor field-effect transistor fabrication processes, which are suitable for field-effect transistors at the 14 nm, 11 nm, or even further technology node.

摘要： The present disclosure is related to semiconductor technologies and discloses a semiconductor device and its method of making. In the present disclosure, a transistor's source and drain are led out by concurrently formed metal-semiconductor compound contact regions at the source and drain and metal-semiconductor compounds in vias formed at positions corresponding to the source and drain. Because the metal-semiconductor compound has relatively low resistivity, the resistance of the metal-semiconductor compounds in the vias can be minimized. Also, because the material used to fill the vias and the material forming the source/drain contact regions are both metal-semiconductor compound, contact resistance between the material filling the vias and the metal-semiconductor compound source/drain contact regions can be minimized. Furthermore, because the material filling the vias is metal-semiconductor compound, the conducting material in the vias and dielectric material in the insulator layer can form good interface and have good adhesion properties, and the conducting material would not cause structural damage in the dielectric material. Thus, there is no need to form a barrier layer between the insulator layer and the material filling the vias.
摘要翻译：本公开涉及半导体技术，并公开了一种半导体器件及其制造方法。在本公开中，晶体管的源极和漏极由在源极和漏极处形成的通孔中形成的金属 - 半导体化合物接触区域和与源极和漏极相对应的通孔中的金属 - 半导体化合物引出。因为金属 - 半导体化合物具有相对低的电阻率，所以可以使过孔中金属 - 半导体化合物的电阻最小化。此外，由于用于填充通孔的材料和形成源极/漏极接触区域的材料都是金属 - 半导体化合物，所以填充通孔的材料与金属 - 半导体化合物源极/漏极接触区域之间的接触电阻可以被最小化。此外，由于填充过孔的材料是金属 - 半导体化合物，所以绝缘体层中的通孔和电介质材料中的导电材料可以形成良好的界面并且具有良好的粘合性能，并且导电材料不会在介电材料中引起结构损坏。因此，不需要在绝缘体层和填充通孔的材料之间形成阻挡层。

摘要： The present invention puts forward a body-contact SOI transistor structure and method of making. The method comprises: forming a hard mask layer on the SOI; etching an opening exposing SOI bottom silicon; wet etching an SOI oxide layer through the opening; depositing a polysilicon layer at the opening followed by anisotropic dry etching; depositing an insulating dielectric layer at the opening followed by planarization; forming a gate stack structure by deposition and etching, and forming source/drain junctions of the transistor using ion implantation. By using the present invention, body contact for SOI field-effect transistors can be effectively formed, thereby eliminating floating-body effect in the SOI field-effect transistors, and improving heat dissipation capability of the SOI transistors and associated integrated circuits.
