Description
Technical Field
The application belongs to the technical field of semiconductors, and particularly relates to a liquid source bottle and semiconductor process equipment.
Background
During a Metal-organic chemical vapor deposition (MOCVD) process, gaseous Metal-organic compounds are decomposed on a wafer on a susceptor surface within a process chamber and a Metal or Metal compound film is thermally deposited on the wafer surface. The gaseous metal organic compound can be obtained by the following process: the liquid metal organic compound is stored in a source bottle as a source, namely, the liquid source, the space except the liquid source in the source bottle is in a low-pressure state, a certain amount of gaseous source can be evaporated on the surface of the liquid source, inert gas with certain flow and pressure is introduced into the source bottle as carrier gas, the carrier gas is blown from the surface of the liquid source, the gaseous metal organic compound evaporated in the source bottle, namely, the gaseous source, is carried out of the source bottle, and the carrier gas carrying the gaseous source finally reaches a process chamber through a series of process gas pipelines, so that corresponding CVD reaction is carried out on the surface of a wafer.
During the CVD process, the rate at which the film is deposited on the wafer surface is directly related to the amount of gaseous source that reaches the wafer surface per unit time, which is insufficient to affect the efficiency of the overall deposition process and thus the overall throughput of the apparatus. According to the principle of evaporation of a liquid, the amount of liquid evaporated into a gaseous state per unit time is proportional to the liquid temperature and to the liquid surface area under a certain pressure, while the process temperature and pressure of the source used for a particular CVD reaction are determined, so that the amount of gaseous source evaporated per unit time in the source bottle is only related to the liquid surface area. Fig. 1 shows a schematic view of a structure of a source bottle adopting a surface blowing mode, wherein a gaseous source 6 is evaporated from the surface of a liquid source 5, a carrier gas enters the source bottle through an air inlet 1 in an air inlet direction 3, flows out of an air outlet 2 in a direction indicated by a flow direction 7 and flows out towards a carrier gas air outlet direction 4 carrying the gaseous source, a filling opening 8 of the source bottle is arranged in the middle of the top and is limited by the condition of equipment, the volume of the source bottle is not increased limitlessly, the surface area of the liquid source in the source bottle is not increased limitlessly, and the surface area of the liquid source is limited by the size of the source bottle and cannot be increased effectively, as in the source bottle shown in fig. 1. Therefore, how to increase the carry-over of a liquid source with a smaller saturated vapor pressure is a key technical problem. In order to improve the overall productivity of the equipment, 2 or more source bottles are often used in parallel connection for a CVD machine to achieve a higher level of the expected source blowout amount, but each time one source bottle is added, a set of auxiliary equipment for the source bottle is added, including a pneumatic valve group, heating and heat-preserving equipment and the like, so that the material cost and the maintenance difficulty of the machine are increased.
Therefore, there is a need for a new liquid source bottle that can greatly increase the surface area of the liquid source inside the source bottle and increase the rate of CVD reactions without increasing the volume of the source bottle.
