    摘要: The invention relates to a method of manufacturing a bipolar transistor on a semiconductor substrate (11) which is provided with a first, a second and a third layer (1,2,3) of a first, second and third semiconductor material respectively, all of a first conductivity type. A first portion of the second layer (2) is transformed into a buried isolation region (15) comprising a first electrically insulating material. A first semiconductor region (6) of the first conductivity type, comprising, for example, a collector region, is formed from a second portion of the second layer (2) adjoining the buried isolation region (15) and a portion of the first layer (1) adjoining the second portion of the second layer (2). Then a base region (7) is formed on the buried isolation region (15) and on the first semiconductor region (6) by transforming the third layer (3) into a second conductivity type, which is opposite to the first conductivity type. Thereafter a second semiconductor region (8) of the first conductivity type, comprising, for example, an emitter region, is formed on a part of the base region (7). This method provides for the formation of a bipolar transistor with an advantageous decrease of the extrinsic collector to base region (6,7) capacitance by the fact that the value of this capacitance is mainly determined by the buried isolation region (15) which has a substantially lower dielectric constant than that of the collector to base region (6,7) junction.

    摘要: The invention relates to a semiconductor device (10) with a substrate (11) and a semiconductor body (12) of silicon which comprises an active region (A) with a transistor (T) and a passive region (P) surrounding the active region (A) and which is provided with a buried conducting region (1) of a metallic material that is connected to a conductive region (2) of a metallic material sunken from the surface of the semiconductor body (12), by which the buried conductive region (1) is made electrically connectable at the surface of the semiconductor body (12). According to the invention, the buried conducting region (1) is made at the location of the active region (A) of the semiconductor body (12). In this way, a very low buried resistance can be locally created in the active region (A) in the semiconductor body (12), using a metallic material that has completely different crystallographic properties from the surrounding silicon. This is made possible by using a method according to the invention. Such a buried low resistance offers substantial advantages both for a bipolar transistor and for a MOS transistor.

    摘要: A method of manufacturing a semiconductor device wherein a laminate structure comprising a sacrificial layer is sandwiched between two etch stop layers (8,11) and which separates a semiconductor membrane (9) from a bulk substrate (1) is used to provide an underetched structure. Access trenches (4) and support trenches (5) are formed in the layered structure through the thickness of the semiconductor layer (9) and through the upper etch stop layer (8). The support trenches extend deeper through the sacrificial layer (12) and the lower etch stop layer and are filled.

    摘要: The present invention relates to a FinFET with separate gates and to a method for fabricating the same. A dielectric gate-separation layer between first and second gate electrodes has an extension in a direction pointing from a first to a second gate layer that is smaller than a lateral extension of the fin between its opposite lateral faces. This structure corresponds with a processing method that starts from a covered basic FinFET structure with a continuous first gate layer, and proceeds to remove parts of the first gate layer and of a first gate-isolation layer through a contact opening to the gate layer. Subsequently, a replacement gate-isolation layer that at the same time forms the gate separation layer fabricated, followed by filling the tunnel with a replacement gate layer and a metal filling.

    摘要: The invention relates to a method of manufacturing a semiconductor device (10) comprising a substrate (11) and a semiconductor body (12) in which at least one semiconductor element (1) is formed, wherein on the substrate (11) a semiconductor layer (2) is formed comprising a mixed crystal of silicon and germanium, further called the silicon-germanium layer (2) and having a lower surface close to the substrate (11) and an upper surface more remote from the substrate (11), and wherein the silicon-germanium layer (2) is subjected to an oxidizing treatment at a surface of the silicon-germanium layer (2) while the other surface of the silicon-germanium layer (2) is protected against the oxidizing treatment by a blocking layer (3). According to the invention, the blocking layer (3) is formed on the upper surface of the silicon-germanium layer (2), a cavity (5) is formed in the semiconductor body below the silicon-germanium layer (2) and the lower surface of the silicon-germanium layer (2) is subjected to the oxidizing treatment through the cavity (2).

This enables e.g. to manufacture in particular a MOSFET on top of or in the silicon-germanium layer (2) with excellent properties and high yield.
