摘要： Methods are disclosed for forming a varied impurity profile for a collector using scattered ions while simultaneously forming a subcollector. In one embodiment, the invention includes: providing a substrate; forming a mask layer on the substrate including a first opening having a first dimension; and substantially simultaneously forming through the first opening a first impurity region at a first depth in the substrate (subcollector) and a second impurity region at a second depth different than the first depth in the substrate. The breakdown voltage of a device can be controlled by the size of the first dimension, i.e., the distance of first opening to an active region of the device. Numerous different sized openings can be used to provide devices with different breakdown voltages using a single mask and single implant. A semiconductor device is also disclosed.

摘要： The present invention provides a unique device structure and method that provides increased transistor performance in integrated bipolar circuit devices. The preferred embodiment of the present invention provides improved high speed performance by providing reduced base resistence. The preferred design forms the extrinsic base by diffusing dopants from a dopant source layer and into the extrinsic base region. This diffusion of dopants forms at least a portion of the extrinsic base. In particular, the portion adjacent to the intrinsic base region is formed by diffusion. This solution avoids the problems caused by traditional solutions that implanted the extrinsic base. Specifically, by forming at least a portion of the extrinsic base by diffusion, the problem of damage to base region is minimized. This reduced damage enhances dopant diffusion into the intrinsic base. Additionally, the formed extrinsic base can have improved resistence, resulting in an improved maximum frequency for the bipolar device. Additionally, the extrinsic base can be formed with a self-aligned manufacturing process that reduces fabrication complexity.

摘要： The preferred embodiment of the present invention provides a buried layer that improves the latch up immunity of digital devices while providing isolation structures that provide noise isolation for both the digital and analog devices. The buried layer of the preferred embodiment is formed to reside within or below the subcollector region in the transistor. Additionally, in the preferred embodiment the subcollector is isolated from buried layer outside the transistor region by deep isolation trenches formed at the edges of the subcollector. Additionally, an array of deep isolation trenches provides increased isolation between devices where needed. Thus, the preferred embodiment of the present invention provides an integrated circuit structure and method that provides improved latchup immunity while also providing improved noise tolerance.

摘要： Methods of manufacturing a semiconductor structure are disclosed including a deep trench isolation in which a channel stop is formed in the form of an embedded impurity region in the substrate prior to the deep trench etch and formation of transistor devices (FEOL processing) on the substrate. In this fashion, the FEOL processing thermal cycles can activate the impurity region. The deep trench isolations are then formed after FEOL processing. The method achieves the reduced cost of forming deep trench isolations after FEOL processing, and allows the practice of sharing of a collector level between devices to continue. The invention also includes the semiconductor structure so formed.

摘要： A bipolar transistor with raised extrinsic base and selectable self-alignment between the extrinsic base and the emitter is disclosed. The fabrication method may include the formation of a predefined thickness of a first extrinsic base layer of polysilicon or silicon on an intrinsic base. A dielectric landing pad is then formed by lithography on the first extrinsic base layer. Next, a second extrinsic base layer of polysilicon or silicon is formed on top of the dielectric landing pad to finalize the raised extrinsic base total thickness. An emitter opening is formed using lithography and RIE, where the second extrinsic base layer is etched stopping on the dielectric landing pad. The degree of self-alignment between the emitter and the raised extrinsic base is achieved by selecting the first extrinsic base layer thickness, the dielectric landing pad width, and the spacer width.
