Technical Field

[0001] Cross - reference to Related Applications This application claims priority to U.S. Patent Application No. 17 / 830,196, entitled "THIN FILM RESISTOR (TFR) DEVICE STRUCTURE FOR HIGH PERFORMANCE RADIO FREQUENCY (RF) FILTER DESIGN," filed on June 1, 2022, the disclosure of which is hereby incorporated by reference in its entirety.

[0002] Aspects of the present disclosure relate to semiconductor devices and integrated passive devices, and more particularly, to thin film resistor (TFR) device structures for high performance radio frequency (RF) filter design.

Background Art

[0003] Wireless communication devices incorporate radio frequency (RF) modules that facilitate the communications and functions desired by users. As wireless systems become more prevalent and include more functions, chip manufacturing has become more complex. Fifth generation (5G) / sixth generation (6G) new radio (NR) wireless communication devices incorporate the latest generation of electronic dies that house many functions and devices in smaller modules with smaller interconnects. As the density of these modules increases, resistors are important for combining and / or distributing RF power.

[0004] Design challenges for mobile radio frequency (RF) chips, such as mobile RF transceivers, include analog / RF performance considerations, including mismatches, noise, and other performance considerations. The design of these mobile RF transceivers involves the use of passive devices, such as resistors, to perform filtering and coupling. These resistors are incorporated into high-power system-on-chip devices, such as application processors and graphics processors.

[0005] In practice, the passive devices of mobile RF transceivers can involve high-performance resistor components. For example, analog integrated circuits use various types of passive devices, such as resistors. The use of resistors can enable high-performance power combiners / dividers filters that synthesize / distribute RF power using resistor components. Unfortunately, conventional resistor components cannot achieve the required isolation due to parasitic capacitive coupling between the electrodes of the resistor components. A thin-film resistor (TFR) device structure is desired to provide the isolation required to enable 5G / 6G front-end applications. SUMMARY OF THE INVENTION

The TFR device structure also includes a first portion of a third metallization layer that couples the first portion of the second metallization layer to the second portion of the second metallization layer.

[0007] A method for manufacturing a thin film resistor (TFR) device structure is described. The method includes forming a first portion of a first metallization layer and a second portion of the first metallization layer on a substrate. The method also includes forming a first portion of a dielectric layer on the first portion of the first metallization layer and forming a second portion of the dielectric layer on the second portion of the first metallization layer.

Embodiments for Carrying Out the Invention

[0011] In connection with the accompanying drawings, the "Embodiments for Carrying Out the Invention" described below are intended as descriptions of various configurations and are not intended to represent the only configuration capable of practicing the concepts described herein. The "Embodiments for Carrying Out the Invention" include specific details aimed at providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0012] The use of the term "and / or" as described in this specification is intended to represent an "inclusive OR", and the use of the term "or" is intended to represent an "exclusive OR". The term "exemplary" used throughout this specification means "serving as an example, instance, or illustration", and should not necessarily be construed as being preferred or advantageous over other exemplary configurations. The term "coupled" used throughout this specification means "connected directly or indirectly through an electrical, mechanical, or other intervening connection (e.g., a switch)", and is not necessarily limited to a physical connection. Additionally, the connection can be made such that the objects are permanently connected or releasably connected. The connection can be through a switch. The term "proximate" used throughout this specification means "adjacent, very close, neighboring, or near". The term "on" used throughout this specification means "directly on" in some configurations and "indirectly on" in other configurations.

[0013] Mobile radio frequency (RF) chips (e.g., mobile RF transceivers) are migrating to deep submicron process nodes due to cost and power consumption issues. The design of mobile RF transceivers is becoming more complex due to additional circuit functions to support communication enhancements such as fifth generation (5G) new radio (NR) / sixth generation (6G) communication systems. Further design challenges related to mobile RF transceivers include the use of passive devices, which directly impact analog RF performance considerations, including incompatibilities, noise, and other performance considerations.

[0014] Passive devices in a mobile radio frequency (RF) transceiver can include high-performance resistor, capacitor, and inductor components. For example, an analog integrated circuit uses various types of passive devices such as integrated capacitors, integrated inductors, and resistor components. Integrated capacitors can include metal-oxide-semiconductor (MOS) capacitors, p-n junction capacitors, metal-insulator-metal (MIM) capacitors, poly-poly capacitors, metal-oxide-metal (MOM) capacitors, and other similar capacitor structures. An inductor is an example of an electrical device used to temporarily store energy in a magnetic field within a wire coil according to an inductance value. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element and can be used to reduce the flow of current, adjust signal levels, divide voltages, bias active elements, and terminate transmission lines. For example, the design of a mobile RF transceiver includes the use of an RF filter having resistors, inductors, and capacitors to meet bandwidth specifications.

[0015] A 5G / 6G radio frequency front-end (RFFE) module can include a combiner / divider filter and / or a directional coupler that includes resistor components, MIM capacitors, and inductors. These 5G / 6G RF front-end applications specify resistor components that synthesize / distribute RF power to enable the high-performance power of the combiner / divider filter. Unfortunately, thin-film resistors (TFRs) available using current integrated passive device (IPD) foundry processes cannot achieve the required isolation due to the parasitic capacitive coupling of the electrodes of the TFRs. Without the option to change the foundry's IPD process flow, it is impossible to implement and realize TFR devices for power combiner / divider filters. Therefore, a TFR device structure with design techniques / optimizations to solve these problems is desired.

[0016] Various aspects of the present disclosure provide a TFR device structure for an RF filter. A process flow for manufacturing a TFR device structure for an RF filter may include a front-end-of-line (FEOL) process, a middle-of-line (MOL) process, and a back-end-of-line (BEOL) process. It should be understood that the term "layer" includes a film and is not construed to indicate a vertical or horizontal thickness unless otherwise stated. As described, the term "substrate" may refer to the substrate of a diced wafer or the substrate of an undiced wafer. Similarly, the terms "chip" and "die" may be used interchangeably.

[0017] As described, a back-end-of-line (BEOL) interconnect layer may refer to a conductive interconnect layer (e.g., a first interconnect layer (M1) or metal 1 M1, metal 2 (M2), metal 3 (M3), metal 4 (M4), etc.) for electrically coupling to front-end-of-line (FEOL) active devices of an integrated circuit. The various BEOL interconnect layers are formed in corresponding BEOL interconnect layers where the underlying BEOL interconnect layer uses a thinner metal layer compared to the upper BEOL interconnect layer. The BEOL interconnect layer may be electrically coupled to a middle-of-line (MOL) interconnect layer. For example, M1 may be connected to an oxide diffusion (OD) layer of the integrated circuit. The MOL interconnect layer may include a zero interconnect layer (M0) for connecting M1 to an active device layer of the integrated circuit. A BEOL first via (V2) may connect M2 to M3 or other layers of the BEOL interconnect layer.

[0018] Aspects of the present disclosure relate to thin film resistor (TFR) device structures for implementing RF filters such as power combiners / divider filters or directional couplers. In some aspects of the present disclosure, the TFR device structure includes a split first metallization layer (e.g., M1). The TFR device structure also includes a dielectric layer portion on the split portions of the M1 metallization layer. In some aspects of the present disclosure, the TFR device structure includes a split M2 metallization layer on each portion of the dielectric layer. In some aspects of the present disclosure, the M1 and M2 metallization layers are split to provide the required separation defined by the TFR device structure. This configuration of the TFR device structure can correspond to the required radio frequency (RF) response and can also meet the design target specifications of the power combiner / divider filter.

[0019] FIG. 1 is a schematic diagram of a radio frequency front end (RFFE) module 100 that uses a filter 104 (e.g., an RF filter implemented with a TFR device structure). The RFFE module 100 includes a power amplifier 102, a filter 104, and a radio frequency (RF) switch module 106. The power amplifier 102 amplifies a signal (s) to a certain power level for transmission. The filter 104 filters the input / output signal according to various different parameters including frequency, insertion loss, rejection, or other similar parameters. Additionally, the RF switch module 106 can select a particular portion of the input signal for passing to the rest of the RFFE module 100.

[0020] The radio frequency front end (RFFE) module 100 also includes a tuner circuit 112 (e.g., a first tuner circuit 112A and a second tuner circuit 112B), a second diplexer 190, a capacitor 116, an inductor 118, a ground terminal 115, and an antenna 114. The tuner circuit 112 (e.g., the first tuner circuit 112A and the second tuner circuit 112B) includes components such as a tuner, a portable data entry terminal (PDET), and a housekeeping analog-to-digital converter (HKADC). The tuner circuit 112 can perform impedance matching (e.g., voltage standing wave ratio (VSWR) optimization) for the antenna 114. The RFFE module 100 also includes a passive combiner 108 coupled to a wireless transceiver (WTR) 120. The passive combiner 108 combines the detected power from the first tuner circuit 112A and the second tuner circuit 112B. The wireless transceiver 120 processes the information from the passive combiner 108 and provides this information to a modem 130 (e.g., a mobile station modem (MSM)). The modem 130 provides a digital signal to an application processor (AP) 110.

[0021] As shown in FIG. 1, the second diplexer 190 is between the tuner component of the tuner circuit 112 and the capacitor 116, inductor 118, and antenna 114. From the radio frequency front end (RFFE) module 100 to the chipset including the wireless transceiver 120, modem 130, and application processor 110, the second diplexer 190 may be disposed between the antenna 114 and the tuner circuit 112 to provide high system performance. Also, the second diplexer 190 performs frequency domain multiplexing for both high-band and low-band frequencies. After the second diplexer 190 performs its frequency multiplexing function on the input signal, the output of the second diplexer 190 is supplied to an optional inductor / capacitor (LC) network including the capacitor 116 and inductor 118. The LC network may provide additional impedance matching components for the antenna 114 as needed. Next, a signal having a specific frequency is transmitted or received by the antenna 114. Although a single capacitor and inductor are shown, multiple components are also contemplated.

[0022] FIG. 2 is a schematic diagram of a radio frequency integrated circuit (RFIC) chip 200 having a wireless local area network (WLAN) (e.g., Wi-Fi) module 150 and a radio frequency front end (RFFE) module 170 for a chipset 210. The Wi-Fi module 150 includes a first diplexer 162 that communicatively couples an antenna 164 to a WLAN module 152. A first RF switch 160 communicatively couples the first diplexer 162 to the WLAN module 152. The RFFE module 170 includes a second diplexer 190 that communicatively couples an antenna 192 to a wireless transceiver (WTR) 120 via a filter 172 (e.g., an RF filter implemented with a TFR device structure). A second RF switch 180 communicatively couples the second diplexer 190 to the filter 172.

[0023] The WLAN module 152 of the WTR120 and the Wi-Fi module 150 is coupled to a modem (mobile station modem (MSM), e.g., a baseband modem) 130 that is powered by a power supply 202 via a power management integrated circuit (PMIC) 140. The chipset 210 also includes capacitors 144 and 148 and an inductor (s) 146 to provide signal integrity. Each of the PMIC 140, the modem 130, the WTR120, and the WLAN module 152 includes capacitors (e.g., 142, 132, 122, and 154) and operates according to a clock 204. Additionally, the inductor 146 couples the modem 130 to the PMIC 140. The shape and arrangement of the various inductor components and capacitor components in the RFIC) chip 200 can reduce electromagnetic coupling between the components. The design of the RFFE module 170 includes a filter 172, which can be an RF filter implemented with a TFR device structure as shown, for example, in FIG. 3, according to aspects of the present disclosure.

[0024] FIG. 3 is a block diagram showing a cross-sectional view of a radio frequency front end (RFFE) module 300 including a semiconductor die and an integrated passive device (IPD) filter die, according to aspects of the present disclosure. In this example, the RFFE module 300 includes a semiconductor die 350 and an IPD filter die 320 supported by a substrate 310. The semiconductor die 350 can be an active die having a semiconductor substrate 360 (e.g., an active silicon substrate) coupled to package balls 302 via a back end of line (BEOL) layer 370. The BEOL layer 370 includes a plurality of BEOL metallization layers (M1, M2, M3,..., Mn) on the semiconductor substrate 360 (e.g., a diced silicon wafer). The redistribution layer 312 is coupled to the package balls 302.

[0025] The IPD filter die 320 includes a substrate 330 (e.g., a passive substrate) coupled to the package ball 302 via a back-end-of-line (BEOL) layer 340. The redistribution layer 312 is coupled to the IPD filter die 320 via the package ball 302. In some aspects of the present disclosure, the substrate 330 is composed of glass, and the IPD filter die 320 is a glass-substrate integrated passive device (GIPD) filter die. The IPD filter die 320 may implement a fifth-generation (5G) new radio (NR) / sixth-generation (6G) power combiner / divider filter or a directional coupler.

[0026] The RFFE module 300 may include a power combiner / divider filter including resistor components, MIM capacitors, and inductors. The RFFE module 300 may specify resistor components for combining / distributing RF power to enable a high-performance power combiner / divider filter. Unfortunately, thin-film resistors (TFRs) obtained from current IPD foundry processes cannot achieve the required isolation due to parasitic capacitive coupling between the electrodes of the TFR device. Without the option to change the foundry IPD process flow, it is impossible to implement and realize a TFR device to meet the specifications of the power combiner / divider filter. In some aspects of the present disclosure, the IPD filter die 320 includes a TFR device structure for an RF filter, as further shown in FIGS. 4A and 4B.

[0027] Figures 4A and 4B are block diagrams showing a radio frequency integrated circuit (RFIC) chip including a metal-insulator-metal (MIM) capacitor and a thin film resistor (TFR) device for a radio frequency (RF) filter according to aspects of the present disclosure.

Also, the TFR device structure 420 includes a dielectric layer 426 on the first portion 422 and the second portion 424 of the M1 metallization layer. Also, the TFR device structure 420 further includes an M2 metallization layer 428 on the dielectric layer 426. The M2 metallization layer 428 may be composed of a TFR layer such as titanium nitride (TiN), tantalum nitride (TaN), nickel chromium (NiCr), or other similar conductive materials for resistors. Further, a first portion 430 and a second portion 432 of a third metallization layer (e.g., M3 metallization layer) are coupled to the M2 metallization layer 428 via a via V2, completing the formation of the TFR device structure 420.

In this configuration, the aspect ratio (AR) between the length and width of a unit cell of the first TFR device structure 560 (e.g., the M1 metallization layer portion) is about 1.5. Further, the space between portions of the M1 metallization layer is about one fifteenth (1 / 15) of the length. This configuration is available through a low-cost and high-degree integrated passive device (IPD) process and implements a high-performance power combiner (PC) with the required separation that cannot be achieved with conventional TFR designs. This first TFR device structure 560 can correspond to the required radio frequency (RF) response and can also meet the design target specifications of a power combiner filter.
