Patent number: 8704335Abstract: A bipolar transistor is fabricated having a collector (52) in a substrate (1) and a base (57, 58) and an emitter (59) formed over the substrate. The base has a stack region (57) which is laterally separated from the emitter (59) by an electrically insulating spacer (71). The insulating spacer (71) has a width dimension at its top end at least as large as the width dimension at its bottom end and forms a ?-shape or an oblique shape. The profile reduces the risk of silicide bridging at the top of the spacer in subsequent processing, while maintaining the width of emitter window.Type: GrantFiled: March 30, 2011Date of Patent: April 22, 2014Assignee: NXP, B.V.Inventors: Tony Vanhoucke, Johannes Josephus Theodorus Marinus Donkers, Hans Mertens, Philippe Meunier-Beillard

Patent number: 8541812Abstract: A semiconductor device (10) comprising a bipolar transistor and a field effect transistor within a semiconductor body (1) comprising a projecting mesa (5) within which are at least a portion of a collector region (22d and 22e) and a base region (33d) of the bipolar transistor. The bipolar transistor is provided with a first insulating cavity (92) provided in the collector region (22d and 22e). The base region (33d) is narrower in the plane of the substrate than the collector region (22d and 22e) due to a second insulating cavity (94) provided around the base region (33d) and between the collector region (22d and 22e) and the emitter region (4). By blocking diffusion from the base region the first insulating cavity (92) provides a reduction in the base collector capacitance and can be described as defining the base contact.Type: GrantFiled: February 26, 2009Date of Patent: September 24, 2013Assignee: NXP B.V.Inventors: Philippe Meunier-Beillard, Mark C.

Patent number: 8431966Abstract: Methods for manufacturing a bipolar transistor semiconductor device are described, along with devices fabricated in accordance with the methods. The methods include the steps of forming a stack of layers over a semiconductor body comprising a window definition layer (18,38), a layer (20) of semiconductor material, a first insulating layer (22), and a second insulating layer (24) which is selectively etchable with respect to the first insulating layer. A trench (26) is then etched into the stack down to the window definition layer. The portion of the trench extending through the second insulating layer is widened to form a wider trench portion (28) therethrough. A window (36) is defined in the window definition layer which is aligned with the wider trench portion, and serves to define the base-collector or base-emitter junction in the finished device.Type: GrantFiled: May 11, 2009Date of Patent: April 30, 2013Assignee: NXP B.V.Inventors: Philippe Meunier-Beillard, Erwin Hijzen, Johannes J.
