Abstract

A method of forming a partially silicided element is provided. A silicided structure including a silicide layer on a base structure is formed. A dielectric region is formed over the silicided structure. The dielectric region is etched to form a contact opening exposing a first area of the silicide layer and a tub opening exposing a second area of the silicide layer. A conformal metal is deposited to (a) fill the contact opening to define a contact and (b) form a cup-shaped metal structure in the tub opening. Another etch is performed to remove the cup-shaped metal structure in the tub opening, to remove the underlying silicide layer second area and to expose an underlying area of the base structure, wherein the silicide layer first area remains intact. The base structure with the intact silicide layer first area and removed silicide layer second area defines the partially silicided element.

Abstract

A method of forming a partially silicided element is provided. A silicided structure including a silicide layer on a base structure is formed. A dielectric region is formed over the silicided structure. The dielectric region is etched to form a contact opening exposing a first area of the silicide layer and a tub opening exposing a second area of the silicide layer. A conformal metal is deposited to (a) fill the contact opening to define a contact and (b) form a cup-shaped metal structure in the tub opening. Another etch is performed to remove the cup-shaped metal structure in the tub opening, to remove the underlying silicide layer second area and to expose an underlying area of the base structure, wherein the silicide layer first area remains intact. The base structure with the intact silicide layer first area and removed silicide layer second area defines the partially silicided element.

Abstract

An apparatus includes a power-over-Ethernet (POE) interface to be connected to a powered device (PD) over an Ethernet cable and a control circuit. The control circuit is to measure a voltage provided by the apparatus through the Ethernet cable, determine that the voltage has dropped by at least a given voltage change, based on a determination that the voltage has dropped by at least the given voltage change, determine whether or not a predetermined quantity of Maintain Power Signature (MPS) signals have been missed within a given time frame, and, based on a determination that the predetermined quantity of MPS signals has not been missed within the given time frame, determine that the PD is still connected to the apparatus.

Abstract

An apparatus and method for determining electrical characteristics has an acquisition circuit and a control circuit. The control circuit causes a first modulation circuit to issue a first set of modulated signals to a first source of alternating current energy, wherein the first set of modulated signals has a first deadtime and wherein a high side switch and a low side switch of the first modulation circuit are turned off. The control circuit further causes the acquisition circuit to acquire a first electrical characteristic of the first source of alternating current energy from the first source of alternating current energy during the first deadtime.

Abstract

Motion detection apparatuses are disclosed. The motion detection may be performed using one or more of a sub-window of a predetermined time window, a predetermined threshold value that is settable responsive to changes in one or more environmental factors, or a detection trigger. An apparatus includes a processor and an analog-to-digital converter (ADC) circuitry to sample a reflected predetermined pattern signal to generate reflected predetermined pattern samples. The processor captures collections of the reflected predetermined pattern samples corresponding to a predetermined time window and determines a sum of the collections or sub-collections. The processor determines an average of magnitudes of the determined sum and determines that a moving object is detected responsive to a predetermined threshold value.

Abstract

A device with boot code, first mutable code stored in non-volatile memory, a first owner information stored in the non-volatile memory, and an SRAM with an SRAM physically unclonable function (SRAM PUF) region. Boot code may generate a first unique private key based on both the first owner information and a portion of the SRAM PUF region, wherein the first unique private key may not be directly accessible by the first mutable code; generate a first unique private keycode corresponding to the first unique private key; and provide the first mutable code with the first unique private keycode corresponding to the first unique private key. First mutable code may use the first unique private keycode to cause data to be signed with the first unique private key and generate a first unique mutable code private key based on at least a portion of the SRAM PUF region.

The apparatus may include a control circuit to control a first phase of a power converter having a plurality of phases, and a phase matching circuit. The phase matching circuit may remove a DC component from an output ripple voltage of the converter, detect when respective ones of the plurality of phases begins generating its respective phase current and output a phase detector signal, extract a signal proportional to the first phase current and a signal proportional to either the remaining or total phase currents, output first and second voltages respectively proportional to the average of the first phase current and the remaining or total phase current, and output a corrective signal based on the difference between the first and second voltage. The control circuit may control the first phase based on the corrective signal.

Abstract

One or more examples relate to inverting current amplification and related touch systems. An apparatus includes a first transistor, a second transistor, and a feedback loop. The first transistor and the second transistor provide controlled current at the second transistor that is a copy of current at the first transistor when respective drain-source voltages of the first transistor and the second transistor are substantially equal. The feedback loop sets respective drain-source voltages of the first transistor and the second transistor to be substantially equal, wherein a responsiveness of the feedback loop is proportional to a set transconductance of the feedback loop.

Metal-Oxide-Metal (MOM) Capacitors for Integrated Circuit Monitoring

Abstract

An array of metal-oxide-metal (MOM) capacitors formed in an integrated circuit (IC) structure may be used for evaluating misalignments between patterned layers of the IC structure. The array of MOM capacitors may be formed in a selected set of patterned layers, e.g., a via layer formed between a pair of metal interconnect layers. The MOM capacitors may be programmed with different patterned layer alignments (e.g., built in to photomasks or reticles used to form the patterned layers) to define an array of different alignments. When the MOM capacitors are formed on the wafer, the actual patterned layer alignments capacitors may differ from the programmed layer alignments due a process-related misalignment. The MOM capacitors may be subjected to electrical testing to identify this process-related misalignment, which may be used for initiating a correcting action, e.g., adjusting a manufacturing process or discarding misaligned IC structures or devices.
