  • Patent number: 7157337
    Abstract: Consistent with an example embodiment according to the invention, a material for the intermediate layer is chosen which can be selectively etched with respect to the dielectric layer. Before the deposition of the first conductor layer, the intermediate layer is removed at the location of the first channel region, and after the deposition of the first conductor layer and the removal thereof outside the first channel region and before the deposition of the second conductor layer, the intermediate layer is removed at the location of the second channel region. Thus, field effect transistors (FETs) are obtained in a simple manner and without damage to their gate dielectric. Preferably, a further intermediate layer is deposited on the intermediate layer which can be selectively etched with respect thereto.

  • Patent number: 7001838
    Abstract: The invention relates to a method of manufacturing a semiconductor device, comprising the provision of a substrate with a layer of silicon thereon, an inorganic anti-reflective layer applied to the layer of silicon, and a resist mask applied to the inorganic anti-reflective layer, which method comprises the steps of: patterning the inorganic anti-reflective layer by means of the resist mask, patterning the layer of silicon, removing the resist mask, and removing the inorganic anti-reflective layer by means of etching with an aqueous solution comprising hydrofluoric acid in a low concentration, which aqueous solution is applied at a high temperature.

  • Patent number: 6703270
    Abstract: A method of manufacturing a semiconductor device comprises the steps of: forming a patterned masking layer (3) of insulating material at a surface (2) of a semiconductor body (1), etching the semiconductor body (1) through the patterned masking layer (3) so as to form a trench (8) in the semiconductor body (1), applying an insulating layer (10) which fills the trench (8) in the semiconductor body (1), the insulating layer (10) exhibiting a trough (11) above the trench (8), which trough (11) has a bottom area (12) lying substantially above the surface (2) of the semiconductor body (1), subjecting the semiconductor body (1) to a planarizing treatment so as to form a substantially planar surface (15), subjecting the semiconductor body (1) to a further treatment so as to expose the semiconductor body (1) and form a field isolating region (17), characterized in that the insulating layer (10) is removed substantially to the bottom area (12) of the trough (11) by means of chemical mechanical polishing using fi

  • Patent number: 6686297
    Abstract: A method of manufacturing an electronic device, in particular but not exclusively a semiconductor device, in which method a substrate (2) is placed inside a process chamber (1) and a surface (3) of the substrate (2) is subjected to an ozone treatment comprising the steps of: providing a liquid onto the surface (3) of the substrate (2) via first supply means, introducing a solution comprising a liquid carrier solvent and ozone gas into the process chamber (1) via second supply means, without bringing about direct contact between the solution and the surface (3) of the substrate (2).

  • Patent number: 6497238
    Abstract: A method of manufacturing electronic devices, in particular, but not exclusively, semiconductor devices, and apparatus for carrying out such a method, in which method substrates 1, which are provided at a surface 2 with a silicon oxide-containing material 3 to be removed, are subjected, while being divided into successive batches, to a wet treatment in a bath 4 containing a solution 5 of hydrofluoric acid in water. During this wet treatment the conductivity of the solution 5 is monitored and the silicon oxide-containing material 3 is removed, thereby forming ionic components. The monitored conductivity is brought to approximately a desired conductivity at time intervals by adding hydrofluoric acid and/or water to the solution 5 inside the bath 4.

  • Patent number: 6392417
    Abstract: Arrangement and method for detecting the end of life of an aqueous bath utilized in semiconductor processing, the bath containing water, an amount of hydrogen peroxide and an amount of a predetermined chemical species, which is either an acid or a base, in accordance with the following steps: adding a predetermined additional amount of the hydrogen peroxide and/or the predetermined chemical species at predetermined time intervals, measuring at least one parameter of the aqueous bath, thereby obtaining a measured parameter value, the at least one parameter being selected from a set of parameters including bath pH and bath conductivity; reading a predicted value of said at least one parameter from a memory storing a curve of predicted values of said at least one parameter as a function of time, said curve depending on said predetermined additional amount of said hydrogen peroxide and/or said predetermined chemical species, and depending on said predetermined time intervals; establishing the end of life of said
