Electronic Elements And Devices With Trench Under Bond Pad Feature

View page
US Patent:
8134241, Mar 13, 2012
Filed:
Jul 8, 2011
Appl. No.:
13/179295
Inventors:
Jeffrey K. Jones - Chandler AZ, US
Margaret A. Szymanowski - Chandler AZ, US
Michele L. Miera - Gilbert AZ, US
Xiaowei Ren - Phoenix AZ, US
Wayne R. Burger - Phoenix AZ, US
Mark A. Bennett - Glasgow, GB
Colin Kerr - South Lanarkshire, GB
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H01L 23/48
US Classification:
257786, 257E2159, 257E23023
Abstract:
Electronic elements having an active device region and bonding pad (BP) region on a common substrate desirably include a dielectric region underlying the BP to reduce the parasitic impedance of the BP and its interconnection as the electronic elements are scaled to higher power and/or operating frequency. Mechanical stress created by plain (e. g. , oxide only) dielectric regions can adversely affect performance, manufacturing yield, pad-to-device proximity and occupied area. This can be avoided by providing a composite dielectric region having electrically isolated inclusions of a thermal expansion coefficient (TEC) less than that of the dielectric material in which they are embedded and/or closer to the substrate TEC. For silicon substrates, poly or amorphous silicon is suitable for the inclusions and silicon oxide for the dielectric material. The inclusions preferably have a blade-like shape separated by and enclosed within the dielectric material.

Abstract:
A multiple-path amplifier (e.g., a Doherty amplifier) includes a first transistor (e.g., a main amplifier FET), a second transistor (e.g., a peaking amplifier FET), a combining node, and a shunt-inductance circuit. The first and second amplifiers and the combining node structure are integrally-formed with a semiconductor die, and the shunt-inductance circuit is integrated with the die. Outputs of the first and second transistors are electrically coupled to the combining node structure. The shunt-inductance circuit is electrically coupled between the combining node structure and a ground reference node. The shunt-inductance circuit includes a shunt inductance (e.g., including wirebond(s) and/or spiral inductor(s)) that is integrated with the semiconductor die. The multiple-path amplifier also may include an integrated phase shifter/impedance inverter coupled between the outputs of the first and second transistors, and which is configured to impart a 90-degree phase delay between intrinsic drains of the first and second transistors.

International Classification:
H03F 1/02
H03F 3/21
H01L 23/00
H01L 23/66

Abstract:
A multiple-path amplifier (e.g., a Doherty amplifier) includes a semiconductor die, a radio frequency (RF) signal input terminal, a combining node structure integrally formed with the semiconductor die, and first and second amplifiers (e.g., main and peaking amplifiers) integrally formed with the die.

A phase delay between the outputs of the first and second amplifiers is substantially equal to 90 degrees. The second amplifier may be divided into two amplifier portions that are physically located on opposite sides of the first amplifier.

H01L 23/498
Abstract:
A Doherty amplifier module includes a substrate, an RF signal splitter, a carrier amplifier die, and first and second peaking amplifier dies. The RF signal splitter divides an input RF signal into first, second, and third input RF signals, and conveys the input RF signals to splitter output terminals. The carrier amplifier die includes one or more first power transistors configured to amplify, along a carrier signal path, the first input RF signal to produce an amplified first RF signal. The peaking amplifier dies each include one or more additional power transistors configured to amplify, along first and second peaking signal paths, the second and third input RF signals to produce amplified second and third RF signals. The dies are coupled to the substrate so that the RF signal paths through the carrier and one or more of the peaking amplifier dies extend in substantially different (e.g., orthogonal) directions.
