As wireless systems become more ubiquitous and include more capabilities, the production of chips has become more complex. Fifth generation (5G) / sixth generation (6G) new radio (NR) wireless communication devices incorporate the latest generation of electronic dies that pack many features and devices into smaller modules with increasingly smaller interconnects. As the density of these modules increases, resistors are very important for combining and / or distributing RF power.
[0005] The design challenges of mobile radio frequency (RF) chips, such as mobile RF transceivers, include analog / RF performance considerations, including mismatch, noise and other performance considerations. The design of these mobile RF transceivers includes the use of passive devices, such as resistors, for example, to perform filtering and coupling. These resistors are integrated into high-power system-on-chip devices, such as application processors and graphics processors.
[0006] In practice, the passive components of mobile RF transceivers may involve high performance resistor components. For example, analog integrated circuits use various types of passive components, such as resistors. The use of resistors can realize high performance power combiner / divider filters that use resistor components to combine / divide RF power. Unfortunately, due to parasitic capacitive coupling between electrodes of the resistor component, conventional resistor components cannot achieve the desired isolation. It is expected that a thin film resistor (TFR) device structure for providing the desired isolation to achieve 5G / 6G front-end applications. Summary of the invention

In order to provide a comprehensive understanding of the various concepts, the specific embodiments include specific details. However, it is apparent to those skilled in the art that these concepts can be practiced without these specific details.

As described herein, the term "on..." used throughout the specification means "directly on..." in some configurations, and "indirectly on..." in other configurations.
[0022] Mobile radio frequency (RF) chips (e.g., mobile RF transceivers) have migrated to deep submicron process nodes for cost and power consumption considerations. Additional circuit functions to support communication enhancements such as fifth generation (5G) new radio (NR) / sixth generation (6G) communication systems complicate the design of mobile RF transceivers. Further design challenges for mobile RF transceivers include the use of passive components that directly impact analog RF performance considerations, including mismatch, noise, and other performance considerations.
[0023] Passive devices in mobile radio frequency (RF) transceivers may include high performance resistors, capacitors and inductor components. For example, analog integrated circuits use various types of passive devices, such as integrated capacitors, integrated inductors and resistor components. Integrated capacitors may include metal-oxide-semiconductor (MOS) capacitors, pn junction capacitors, metal-insulator-metal (MIM) capacitors, polysilicon-polysilicon capacitors, metal-oxide-metal (MOM) capacitors and other similar capacitor structures. Inductors are examples of electrical devices for temporarily storing energy in a magnetic field within a wire coil according to an inductance value. Resistors are passive two-terminal electrical components that implement resistance as circuit elements, which can be used to reduce current flow, adjust signal levels, divide voltages, bias active components and terminate transmission lines. For example, the design of mobile RF transceivers includes using RF filters with resistors, inductors and capacitors to meet bandwidth specifications.
[0024] 5G / 6G RF front-end (RFFE) modules may include combiner / divider filters and / or directional couplers having resistor components, MIM capacitors and inductors. These 5G / 6G RF front-end applications specify resistor components to combine / divide RF power to achieve high performance power of combiner / divider filters. Unfortunately, thin film resistors (TFRs) available using current integrated passive device (IPD) casting processes cannot achieve the desired isolation due to parasitic capacitive coupling of the electrodes of the TFR. Without the option of modifying the casting IPD process flow, it is impossible to implement and realize TFR devices for power combiner / divider filters. Therefore, it is desirable to have a TFR device structure with design techniques / optimizations to address these problems.
[0025] Various aspects of the present disclosure provide a TFR device structure for an RF filter. The 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 to be interpreted as indicating a vertical or horizontal thickness unless otherwise specified. As described, the term "substrate" may refer to a substrate of a cut wafer or may refer to a substrate of an uncut wafer. Similarly, the terms chip and die may be used interchangeably.
[0026] 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 one M1, metal two (M2), metal three (M3), metal four (M4), etc.) for electrically coupling to a front-end-of-line (FEOL) active device of an integrated circuit. Various BEOL interconnect layers are formed at corresponding BEOL interconnect layers, wherein lower BEOL interconnect layers use thinner metal layers relative to upper BEOL interconnect levels. The BEOL interconnect layer may be electrically coupled to a middle-of-line (MOL) interconnect layer, for example, to connect M1 to an oxide diffusion (OD) layer of an integrated circuit. The MOL interconnect layer may include a zero interconnect layer (M0) for connecting M1 to an active device layer of an integrated circuit. A BEOL first via (V2) may connect M2 to M3 or other layers in the BEOL interconnect layer.
[0027] Various aspects of the present disclosure relate to a thin film resistor (TFR) device structure that implements an RF filter (such as a power combiner / divider filter or a directional coupler). 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 portion of the M1 metallization layer. In some aspects of the present disclosure, the TFR device structure includes a split M2 metallization layer on a corresponding portion of the dielectric layer. In some aspects of the present disclosure, the M1 and M2 metallization layers are split to provide the desired isolation specified by the TFR device structure. This configuration of the TFR device structure can match the desired radio frequency (RF) response and also meet the power combiner / divider filter design target specifications.
[0028] Figure 1 1 is a schematic diagram of a radio frequency front end (RFFE) module 100 using a filter 104 (e.g., an RF filter implemented using 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 the signal to a certain power level for transmission. The filter 104 filters the input / output signal according to various parameters, including frequency, insertion loss, rejection, or other similar parameters. In addition, the RF switch module 106 can select certain portions of the input signal to pass to the rest of the RFFE module 100.
[0029] 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 duplexer 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 may perform impedance tuning (e.g., voltage standing wave ratio (VSWR) optimization) on the antenna 114. The RFFE module 100 also includes a passive combiner 108 coupled to the wireless transceiver (WTR) 120. The passive combiner 108 combines the power detected 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 (eg, a mobile station modem (MSM)). The modem 130 provides the digital signal to the application processor (AP) 110.
[0030] like Figure 1As shown, the second duplexer 190 is between the tuner components of the tuner circuit 112 and the capacitor 116, the inductor 118 and the antenna 114. The second duplexer 190 can be placed between the antenna 114 and the tuner circuit 112 to provide high system performance from the radio frequency front end (RFFE) module 100 to the chipset including the wireless transceiver 120, the modem 130 and the application processor 110. The second duplexer 190 also performs frequency domain multiplexing on both the high-band frequency and the low-band frequency. After the second duplexer 190 performs its frequency multiplexing function on the input signal, the output of the second duplexer 190 is fed to an optional inductor / capacitor (LC) network including capacitors 116 and inductors 118. When necessary, the LC network can provide additional impedance matching components for the antenna 114. Then, a signal with a specific frequency is sent or received by the antenna 114. Although a single capacitor and inductor are shown, multiple components can also be envisioned.
[0031] Figure 2 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 duplexer 162 that communicatively couples an antenna 164 to the WLAN module 152. A first RF switch 160 communicatively couples the first duplexer 162 to the WLAN module 152. The RFFE module 170 includes a second duplexer 190 that communicatively couples an antenna 192 to a wireless transceiver (WTR) 120 through a filter 172 (e.g., an RF filter implemented using a TFR device structure). A second RF switch 180 communicatively couples the second duplexer 190 to the filter 172.
[0032] The WTR 120 and the WLAN module 152 of the Wi-Fi module 150 are coupled to a modem (mobile station modem (MSM), such as a baseband modem) 130 powered by a power source 202 through a power management integrated circuit (PMIC) 140. The chipset 210 also includes capacitors 144 and 148 and an inductor 146 to provide signal integrity. The PMIC 140, modem 130, WTR 120, and WLAN module 152 each include capacitors (e.g., 142, 132, 122, and 154) and operate according to a clock 204. In addition, the inductor 146 couples the modem 130 to the PMIC 140. The geometry and arrangement of the various inductor and capacitor components in the RFIC) chip 200 can reduce electromagnetic coupling between components. According to aspects of the present disclosure, the design of the RFFE module 170 includes a filter 172, which can be a filter that utilizes, for example, Figure 3The TFR device structure shown is used to implement the RF filter.

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 a package ball 302 through 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). A redistribution layer 312 is coupled to the package ball 302.
[0034] The IPD filter die 320 includes a substrate 330 (e.g., a passive substrate) coupled to the package balls 302 through a back end of line (BEOL) layer 340. The redistribution layer 312 is coupled to the IPD filter die 320 through the package balls 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 can implement a fifth generation (5G) new radio (NR) / sixth generation (6G) power combiner / divider filter or a directional coupler.
[0035] The RFFE module 300 may include a power combiner / divider filter having a resistor component, a MIM capacitor, and an inductor. The RFFE module 300 may specify a resistor component to combine / divide RF power to achieve a high performance power combiner / divider filter. Unfortunately, thin film resistors (TFRs) produced by current IPD casting processes cannot achieve the desired isolation due to parasitic capacitive coupling between electrodes of the TFR device. Without the option of modifying the casting IPD process flow, it is not possible to implement and realize a TFR device that meets 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, such as Figure 4A and Figure 4B Further illustrated in .

The TFR device structure 420 also includes a dielectric layer 426 on the first portion 422 and the second portion 424 of the M1 metallization layer. The TFR device structure 420 also 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 used for resistors. In addition, 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 through vias V2 to complete the formation of the TFR device structure 420.
