  • Patent number: 9769880
    Abstract: Flash light is emitted from flash lamps to the surface of a semiconductor substrate on which a metal layer has been formed for one second or less to momentarily raise temperature on the surface of the semiconductor substrate including the metal layer and an impurity region to a processing temperature of 1000° C. or more. Heat treatment is performed by emitting flash light to the surface of the semiconductor substrate in a forming gas atmosphere containing hydrogen. By heating the surface of the semiconductor substrate to a high temperature in the forming gas atmosphere for an extremely short time period, contact resistance can be reduced without desorbing hydrogen taken in the vicinity of an interface of a gate oxide film for hydrogen termination.

  • Patent number: 9768356
    Abstract: A method is described for forming at least one metal contact on a surface of a semiconductor and a device with at least one metal contact. The method is used for forming at least one metal contact (60) on a surface (11) of a semiconductor (10) and has the steps of: applying a metal layer (20) of palladium onto the semiconductor surface (11), applying a mask (40, 50) onto the metal layer (20), and structuring the palladium of the metal layer (20) using the mask (40, 50), wherein lateral deposits (21) of the metal are formed on sidewalls of the mask by the structuring so that the mask is embedded between the deposits (21) and the structured metal layer (20?) after the structuring. Since the mask is conductive, it can remain embedded in the metal. The deposits and the mask form a part of the contact.

  • Patent number: 9754824
    Abstract: Aspects of the methods and apparatus described herein relate to deposition of tungsten nucleation layers and other tungsten-containing films. Various embodiments of the methods involve exposing a substrate to alternating pulses of a tungsten precursor and a reducing agent at low chamber pressure to thereby deposit a tungsten-containing layer on the surface of the substrate. According to various embodiments, chamber pressure may be maintained at or below 10 Torr. In some embodiments, chamber pressure may be maintained at or below 7 Torr, or even lower, such as at or below 5 Torr. The methods may be implemented with a fluorine-containing tungsten precursor, but result in very low or undetectable amounts of fluorine in the deposited layer.

  • Patent number: 9728472
    Abstract: A method for wafer etching in a deep silicon trench etching process includes the following steps: a. electrostatically absorbing a wafer using an electrostatic chuck, and stabilizing the atmosphere required by the process (S110); b. performing the sub-steps of a main process for the wafer, and the time for the sub-steps of the main process being shorter than the time required by the wafer main process; c. releasing the electrostatic adsorption of the electrostatic chuck on the wafer; d. determining whether the cumulative time of the sub-steps of the main process reaches a predetermined threshold or not, if so, performing the step e (S150), and if not, repeating the operations in the steps a to c (S140); and e. ending a wafer manufacturing process. The etching method avoids the wafer from continuous contact with the electrostatic chuck, reduces electrostatic accumulation on the surface of the wafer, and therefore solves the problem of resist reticulation on the surface of the wafer in the DSIE process.

  • Patent number: 9726651
    Abstract: A double-sided diaphragm micro gas-preconcentrator has a micro-gas chamber which is formed by stacking an upper silicon substrate with a lower silicon substrate with a back-on-face configuration. One or more suspended membranes are provided on every silicon substrate. The silicon where the suspended membrane is provided is completely removed for forming a cavity. A thin-film heater is deposited on every suspended membrane. A sorptive film is coated on an inner wall of every suspended membrane. Thus, the upper and lower sides of the preconcentrator in the present invention are suspended membranes, which improve the area of the sorptive film on the diaphragm. As a result, the preconcentrating factor is improved while keeping the small heat capacity, fast heating rate, and low power consumption features of the planar diaphragm preconcentrator.
