    Abstract: A method of manufacturing an integrated circuit structure forms a first opening in a substrate (100; Figure 1) and lines the first opening with a protective liner. (102) The method deposits a material into the first opening (104) and forms a protective material over the substrate. The protective material includes a process control mark and includes a second opening above, and aligned with, the first opening. (108) The method removes the material from the first opening through the second opening in the protective material. (110) The process control mark comprises a recess within the protective material that extends only partially through the protective material, such that portions of the substrate below the process control mark are not affected by the process of removing the material.

    Abstract: A method of forming at least one Micro-Electro-Mechanical System (MEMS) includes patterning a wiring layer to form at least one fixed plate and forming a sacrificial material on the wiring layer. The method further includes forming an insulator layer of one or more films over the at least one fixed plate and exposed portions of an underlying substrate to prevent formation of a reaction product between the wiring layer and a sacrificial material. The method further includes forming at least one MEMS beam that is moveable over the at least one fixed plate. The method further includes venting or stripping of the sacrificial material to form at least a first cavity.

    Abstract: Ausführungsformen einer verbesserten Transistorstruktur (100) (z. B. einer Bipolartransistor(BT)-Struktur oder Heteroübergang-Bipolartransistor(HBT)-Struktur) und ein Verfahren zur Bildung der Transistorstruktur (100) werden offenbart. Die Ausführungsformen der Struktur können eine dielektrische Schicht (130), die zwischen einer intrinsischen Basisschicht (120) und einer erhabenen extrinsischen Basisschicht (140) angeordnet ist, um die Kollektor-Basis-Kapazität Ccb zu reduzieren, einen seitenwanddefinierten leitenden Streifen (150) für eine Verbindungszone von der intrinsischen Basisschicht (120) zur extrinsischen Basisschicht (140), um den Basis-Widerstand Rb zu reduzieren, und eine dielektrische Abstandsschicht (160) zwischen der extrinsischen Basisschicht (140) und einer Emitterschicht (180) aufweisen, um die Basis-Emitter-Kapazität Cbe zu reduzieren. Die Ausführungsformen des Verfahrens erlauben die Selbstjustierung des Emitters zu Basiszonen und erlauben zudem die selektive Anpassung der Geometrien verschiedener Merkmale (z. B. der Dicke der dielektrischen Schicht (130), der Breite des leitenden Streifens (150), der Breite der dielektrischen Abstandsschicht (160) und der Breite der Emitterschicht (180)), um die Transistorleistungsfähigkeit zu optimieren.

    Abstract: Disclosed are embodiments of an improved transistor structure (100) (e.g., a bipolar transistor (BT) structure or heterojunction bipolar transistor (HBT) structure) and a method of forming the transistor structure (100). The structure embodiments can incorporate a dielectric layer (130) sandwiched between an intrinsic base layer (120) and a raised extrinsic base layer (140) to reduce collector-base capacitance Ccb, a sidewall-defined conductive strap (150) for an intrinsic base layer (120) to extrinsic base layer (140) link-up region to reduce base resistance Rb and a dielectric spacer (160) between the extrinsic base layer (140) and an emitter layer (180) to reduce base- emitter Cbe capacitance. The method embodiments allow for self-aligning of the emitter to base regions and further allow the geometries of different features (e.g., the thickness of the dielectric layer (130), the width of the conductive strap (150), the width of the dielectric spacer (160) and the width of the emitter layer (180)) to be selectively adjusted in order to optimize transistor performance.
