Abstract:
Apparatus and methods are provided for integrally packaging semiconductor IC (integrated circuit) chips and antenna devices which are integrally constructed from package frame structures (e.g., lead frame, package carrier, package core, etc.), to thereby form compact integrated radio/wireless communications systems for millimeter wave applications. For example, an electronic apparatus (30) includes a package frame (11) having an antenna (12) that is integrally formed as part of the package frame (11), an IC (integrated circuit) chip (13) mounted to the package frame (11), interconnects (19) that provide electrical connections to the IC chip (13) and the antenna (12), and a package cover (15).

PROBLEM TO BE SOLVED: To provide an on-chip circuit pad used on a lossy substrate to improve substrate induced losses. SOLUTION: A shielded circuit pad is provided where parasitic capacitance is controlled by the inclusion of a shunt transmission line stub which reduces the substrate induced loss in millimeter-wave application. The circuit pad is located on the substrate with a shield located beneath the circuit pad, and the shunt transmission line stub attached to the circuit pad. Accordingly, controlled impedance is obtained for the millimeter-wave application. The space between the circuit pad and the shield may then be minimized. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a Si-based packaging with integrated passive components for millimeter wave applications. SOLUTION: An apparatus is described incorporating an interposer 1 having a cavity for a portion of an antenna structure 22, having conductor through vias 3, a top Si part 6 having interconnection wiring 72, 73, 74 and having pads for electrically mounting an integrated circuit chip 21 thereon, wherein the top Si part mates with the interposer electrically and mechanically. The interposer and the top Si part may be scaled to provide an array of functional units. This invention overcomes the problem of combining a high efficient antenna with integrated circuit chips in a Si package with signal frequencies from 1 to 100 GHz and the problem of shielding components proximate to the antenna and reduces strain arising from mismatching of TCEs.

Abstract:
Methods are provided for building integrated circuit transformer devices having compact universal and scalable architectures for millimeter wave applications. For example, an integrated circuit transformer (22) is formed on a semiconductor substrate (21) and includes a ground shield (23) formed on the substrate (21), a primary conductor (24) comprising an elongated conductive strip and a secondary conductor (25) comprising an elongated conductive strip. The primary conductor (24) and the secondary conductor (25) are aligned to form a coupled-wire structure that is disposed adjacent to the ground shield (23). The ground shield (23) comprises a pattern of close-ended parallel elongated slots (23a) and parallel conductive strips (23b) that are commonly connected at end portions thereof along edge regions (23c) of the ground shield (23). The slots (23a) and strips (23b) are disposed orthogonal to the primary (24) and secondary (25) conductors. The edge regions (23c) provide current return paths that are collinear to the primary (24) and secondary (25) conductors. The integrated circuit transformer (22) can be used as template or building block, which is parameterized by length, for constructing various integrated circuit devices and modular structures including, but not limited to, power amplifiers, n:l impendence transformers, and power combiners.
