摘要:
The present invention relates generally to an apparatus and a method for forming a pattern, and in particular, to an apparatus and a method for forming a pattern for the formation of quantum dots or wires with 1 ∩ 50 nm dimension using the atomic array of a crystalline material and to the manufacture of functional devices that have such a structure. In the present invention, the functional device means an electronic, magnetic, or optical device that can be fabricated by procedures including the formation process of quantum dots or wires.
摘要:
The present invention generally provides carbon materials and methods for producing the carbon materials that include a polymer-like bonded carbon network, a diamond-like bonded carbon network, a graphene-like bonded carbon network, and at least one stabilizing network of at least one alloying element. The material may further include hydrogen, silicone, and oxygen. The carbon materials are generally produced using plasma deposition while accounting for both thermal and incident particle impact activation for surface reactions, which beneficially enables the production of the carbon material at relevantly low incident flux energy and/or relatively low substrate temperatures.

摘要:
A method of fabricating a dielectric film comprising atoms of Si, C, O and H (hereinafter SiCOH) that has improved insulating properties as compared with prior art dielectric films, including prior art SiCOH dielectric films that are not subjected to the inventive deep ultra-violet (DUV) is disclosed. The improved properties include reduced current leakage which is achieved without adversely affecting (increasing) the dielectric constant of the SiCOH dieletric film. In accordance with the present invention, a SiCOH dielectric film exhibiting reduced current leakage and improved reliability is obtained by subjecting an as deposited SiCOH dielectric film to a DUV laser anneal. The DUV laser anneal step of the present invention likely removes the weakly bonded C from the film, thus improving leakage current.

A substrate dividing method which can thin and divide a substrate while preventing chipping and cracking from occurring. This substrate dividing method comprises the steps of irradiating a semiconductor substrate 1 having a front face 3 formed with functional devices 19 with laser light while positioning a light-converging point within the substrate, so as to form a modified region including a molten processed region due to multiphoton absorption within the semiconductor substrate 1, and causing the modified region including the molten processed region to form a starting point region for cutting; and grinding a rear face 21 of the semiconductor substrate 1 after the step of forming the starting point region for cutting such that the semiconductor substrate 1 attains a predetermined thickness.

zur gegenseitigen Ausrichtung (Registrieren) von Maske und Substrat bei Röntgenstrahl- oder Korpuskularstrahllithographie wird ein Elektronenstrahl (16; Fig. 1) verwendet, der kollateral mit dem Belichtungsstrahl (tonen- oder Röntgenstrahl) verläuft und während des eigentlichen Belichtungsvorgangs unterdrückt wird. Zur Einkopplung des Elektronenstrahls in den Belichtungsstrahlengang wird ein Magnetfeld (7) verwendet; die genaue relative Lage von Maske zu Substrat wird während des Ausrichtvorgangs durch Kippung des Elektronenstrahls ermittelt und die Feinausrichtung während des Belichtens durch entsprechende Kippung des lonenstrahls bzw. Verschiebung des Substrats relativ zum Röntgenstrahl durchgeführt. Die zur Belichtung verwendete Maske (10) besteht aus einer sehr dünnen Siliciumschicht mit einem Musterbereich und einem räumlich davon getrennten Registerbereich. Der Registerbereich besteht aus einer Vielzahl von Durchbrüchen, der Musterbereich aus Sacklöchern.
摘要:
In the manufacture of an infra-red radiation detector device, a body (10) of p-type cadmium mercury telluride is bombarded with ions (11) to etch away a part (21) of the body (10) and to produce from the etched-away part of the body an excess concentration of mercury which acts as a dopant source converting an adjacent part (22) of the body (10) into n-type material. The energy of the bombarding ions is less than 30 keV, and by appropriately choosing the ion dose this conversion can be effected over a depth considerably greater than the penetration depth of the ions (11). A p-n junction (23) can be fabricated in this way for a photo-voltaic detector. The conductivity type conversion may even be effected through the body thickness. The etching and conversion can be localised by masking part of the body surface (20) against the ion bombardment.
