Definitions
- the present invention relates to methods and devices implemented for the fabrication of semiconductors or electromechanical microsystems (MEMS) in semiconductor manufacturing plants.
- the invention relates to means for increasing the efficiency of semiconductor manufacturing plants.
- substrates such as semiconductor wafers (wafers) and / or masks are processed in process chambers, which perform various steps such as deposition steps, engraving steps. Between each step, the substrates are moved between different devices.
- the large number of processing steps (of the order of 400) involves constraints of linking between the processing equipment.
- the substrates are transferred between the equipment.
- the waiting times between the equipment can be long, typically a few hours, it is necessary to store the substrates.
- a plurality of substrate processing equipment, substrate storage means, substrate transport means, and a manufacturing control system (MES) in relation to one another are provided. functional with the substrate processing equipment, with the substrate storage means and with the substrate transport means.
- MES manufacturing control system
- the manufacturing control system is thus adapted to control the equipment for processing substrates, in order to perform satisfactory processing steps.
- the manufacturing control system also instructs the substrates to exit the storage means, and drives the substrate transport means to bring the substrates to the next process equipment in the order of the process steps.
- semiconductor manufacturing plants manage a fixed maximum time between certain stages to avoid the problems associated with these waiting times. These durations are determined empirically, considering the minimum possible time in relation to the number of equipment available for the next step, and the maximum time beyond which there may be pollution problems due to storage.
- the maximum storage time of the substrates depends on a large number of factors: it depends on the final product to be manufactured by the factory, knowing that a factory usually manufactures more than a dozen different products that must pass in the same process equipment with different sequences and stages; it depends on the number of substrates to be treated and the number of substrates present in the treated batches; it depends on the batch history of substrates.
- the problem proposed by the present invention is thus to further increase the efficiency and flexibility of semiconductor manufacturing plants.
- the idea underlying the invention is that the yield reductions observed are mainly the result of pollution problems occurring during the transition phases between the treatment equipment. These pollution problems are related to the gases surrounding the batches of substrates, these gases reacting and creating defects on the substrates. These defects are both proportional to the concentration of the gases present and to the contact time.
- a dose can be defined as the concentration of a gas multiplied by time. From a certain dose, it is considered that problems will appear on the substrates.
- the substrate batches are contained in minienvironments, consisting of storage and transport boxes such as standardized front-opening transport enclosures (FOUPs), standardized bottom-opening storage and transport enclosures (SMI F). ).
- FOUPs front-opening transport enclosures
- SI F bottom-opening storage and transport enclosures
- the present invention is concerned with airborne molecular contamination (AMC) resulting from the presence of reactive gases in the indoor atmosphere of the storage and transport boxes.
- AMC airborne molecular contamination
- This air-borne molecular contamination is a generic designation for molecules that may react with the surface of semiconductor wafers. These chemical reactions can render unusable a semiconductor wafer. In some cases, these molecules appear in the form of salts or metal particles but are first of all gaseous substances.
- acids for example, acids, bases, condensable elements, doping elements.
- the storage and transport boxes are generally made of materials such as polycarbonate, which can in some cases concentrate contaminants and in particular organic, basic, amino, acid and dopant contaminants, which may result from the manufacture of storage boxes and themselves and / or their use.
- the storage and transport boxes are manipulated, which leads to the formation of polluting particles which lodge in the walls of storage and transport boxes, and which contaminate them .
- the particles stuck on the walls of the storage and transport boxes can then peel off, fall back on the substrates contained in these boxes and damage them.
- the contamination of the substrates contained in a storage and transport box increases both as a function of the quantity of contaminants present inside the box, and as a function of the duration of exposure of the substrates to the indoor atmosphere of the storage and transport box.
- This washing step which lasts from 5 to 7 minutes, is followed by a much longer drying step (between 5 hours and 8 hours) comprising for example a step in which the transport chambers are heated by convection of air heated by infrared and centrifuged, followed by a step in which the transport chambers are placed in the open air. Despite drying, there may still be water residues hanging on the walls of the storage and transport boxes.
- the idea is to manage the constraints of sequencing successive displacements of storage boxes and transport batches of substrates, by carrying out a dynamic management taking as a basis the measurement of the dose of a critical gas in the storage and transport boxes.
- the decision on the path of the batch of substrates contained in the storage and transport box, and the decision on the delay between the successive stages of treatment of the substrates, are taken dynamically from this information.
