Abstract

A disclosed semiconductor structure includes a semiconductor layer including a switch area with side-by-side first and second portions and an RF switch with built-in ESD/power surge protection. The RF switch includes series-connected transistors, which include, within the first portion of the switch area, source/drain regions and channel regions positioned laterally between the source/drain regions; and parallel gates adjacent to the channel regions, respectively, and traversing the first portion of the switch area without extending further onto the second portion. Outer source/drain regions are silicided and contacted, whereas inner source/drain regions are unsilicided and uncontacted. The second portion of the switch area is in contact with the source/drain regions in the first area, is unsilicided, and is either undoped or low doped. Thus, the second portion makes up resistive elements connected in parallel to the series-connected transistors.

Abstract

Disclosed are a photonic integrated circuit (PIC) design system and method including optical signal propagation simulation with coupling awareness to account for transition loss due to a difference between at least one specific physical parameter (e.g., curvature radius, material composition, etc.) in optically coupled photonic devices. Coupling awareness can be achieved by including, within a bus of a netlist between the photonic devices, at least one pair of physical data pins: one associated with a specific physical parameter in the light emitting photonic device and the other associated with the specific physical parameter in the light receiving photonic device. Alternatively, coupling awareness can be achieved by running a utility to identify a parameter mismatch between the light emitting and receiving photonic devices, developing a custom coupling cell to account for the mismatch, and inserting the custom coupling cell into a design layout for the PIC.

Abstract

A temperature-adaptive gate driver for a GaN switch includes a gate-to-source voltage adjustment unit and a driver for outputting an on-state gate-to-source voltage to a gate terminal of the switch. The on-state gate-to-source voltage is adjusted based, in part, on temperature of the switch. The amount of adjustment of the on-state gate-to-source voltage with rise in temperature is based, in part, on high-temperature gate-bias reliability data of the switch and is chosen for a favorable trade-off between performance and life-time. The gate-to-source voltage adjustment unit includes a temperature sense element for sensing temperature of the switch and outputs to the driver an output signal based, in part, on temperature. The gate-to-source voltage adjustment unit includes a regulator for receiving a feedback signal based in part, on resistance of the temperature sense element, and for causing a value of the output signal to be responsive to a value of the feedback signal.

Abstract

A disclosed structure includes a power amplifier and circuitry for implementing a biasing scheme that enables high power operation. The power amplifier includes parallel transistor chains connected to input and output transformers. Each chain includes series-connected first, second, and third n-type field effect transistors (NFETs) having front and back gates. The output transformer receives a variable positive power supply voltage generated using average power tracking. Front and back gates of each third NFET receive a positive bias voltage greater than or equal to the variable positive power supply voltage and a negative bias voltage, respectively. By negative back biasing the third NFETs, threshold voltages thereof are raised so a high positive bias voltage can be applied to the front gates to increase power output without violating reliability specifications. Optionally, by making the negative bias voltage temperature dependent, voltages at source regions of the third NFETs are held constant.

Abstract

A disclosed non-volatile memory (NVM) structure is implemented in a fully depleted semiconductor-on-insulator technology processing platform and includes multiple NVM banks with NVM cells including transistors. NVM banks have well regions in a substrate. Transistors of NVM cells of each NVM bank are on an insulator layer above a corresponding well region for that bank. A bias control circuit causes well regions for NVM banks in a standby state to be biased with a reverse back biasing voltage and causes a well region for an NVM bank in an operational state to be biased with a forward back biasing voltage. The bias control circuit can initiate forward back biasing during a cache data retrieval process (before NVM bank access) to ensure that the corresponding well region of an NVM bank at issue is fully biased when, following the cache data retrieval process, access to the NVM bank is still required.

Abstract

A system and computerized method verify product custody along a product manufacturing chain. The method may include verifying a first machine-readable (MR) code for a product level N is valid by comparing the first MR code to a database of valid MR codes. Where the first MR code for the product level N is verified as valid, a second, valid MR code is generated for a next product level N+1 in the database of valid MR codes. In addition, the first MR code for the product level N in the database of valid MR codes is invalidated, so it cannot be used again. The second MR code is formed for use with the next product level N+1, e.g., by the downstream product manufacturer. Custody of product levels along a manufacturing chain can be verified and secured, avoiding bad actors from inserting and profiting from fake parts into the manufacturing chain.

Abstract

A static random access memory (SRAM) cell includes P-type and N-type transistors having secondary gates. A node connected to all secondary gates receives a write enable signal (WEN). A low WEN forward biases the P-type transistors and increases the toggle threshold voltage (Vtth) of the SRAM cell to avoid data switching during a read. A high WEN forward biases the N-type transistors and decreases Vtth during a write. The SRAM cell can be implemented using a fully depleted semiconductor-on-insulator technology, where the secondary gates include corresponding portions of a well region below. In this case, an array of SRAM cells can be above a single well region. Alternatively, the array can be sectioned into sub-arrays above different well regions and a decoder can output sub-array-specific WENs to the different well regions (e.g., with only one WEN being high at a given time to reduce capacitance).

Abstract

A circuit structure includes an enhancement mode transistor and a turn-off slew rate controller for automatically adding drain-source capacitance to the transistor when the transistor is transitioning to an off state. The added drain-source capacitance slows the turn-off slew rate (dV/dt_off) of the transistor without also increasing the turn-off energy loss (E_off). The slew rate controller can include: sensors connected to the drain region for sensing both the drain voltage and the slew rate, respectively; a logic circuit for generating and outputting an enable signal based on output voltages from the sensors; and a capacitance adder for adding to the drain-source capacitance only when the logic value of the enable signal indicates that the drain voltage is at or above a predetermined positive drain voltage level and the slew rate is positive.

Abstract

An integrated circuit includes a fin having a height and a width under a gate of a selected fin-type field effect transistor (FinFET) that is less than the height and width along a remainder of the fin including under gates and for source/drain regions of other FinFETs. The IC includes a first FinFET having a first gate over a fin having a first height and a first width under the first gate, and a second FinFET in the fin adjacent to the first FinFET. The second FinFET has a second gate over the fin, and the fin has, under the second gate only, a second height less than the first height and a second width less than the first width. The resulting reduced channel height and width for the second FinFET increases gate control and reduces gate leakage, which is beneficial for ultra-low current leakage (ULL) devices.

Abstract

A semiconductor device includes a transistor including a gate and a dielectric layer over the gate. A cavity is in the dielectric layer above the gate and a portion of the cavity over the gate has a negative sloped sidewall in the dielectric layer. The negative sloped sidewall provides a portion of the cavity having a trapezoidal cross-section having a first width at a lower end adjacent the gate and a second width smaller than the first width at an upper end. The negative sloped sidewall thus places a wider portion of the cavity closer to the gate, which decreases gate-contact capacitance.

Abstract

An isolation structure for a substrate is disclosed. The isolation structure includes a lower portion having a first liner, and an upper portion having a second liner vertically over the first liner. A first dielectric material is surrounded by the second liner from above and by the first liner from below and laterally. The second liner may include a second dielectric material in at least part thereof. The second liner prevents exposure of end surfaces of a semiconductor layer of the substrate during subsequent processing, which prevents damage such as thinning, agglomeration and/or oxidation that can negatively affect performance of a transistor formed using the semiconductor layer. The second liner also reduces an overall step height of the isolation structure.
