Patent number: 11152356Abstract: In an embodiment, a semiconductor device includes a resistor that overlies a doped region of the semiconductor device. The resistor is formed as an elongated element that is formed into a pattern of a spiral. An embodiment of the pattern of the resistor includes a plurality of revolutions from the starting point to an ending point. The resistor material has one of a separation distance between adjacent revolutions that increases with distance along a periphery of the resistor material or a width of the resistor material that increases with distance along the periphery of the resistor material.Type: GrantFiled: June 20, 2019Date of Patent: October 19, 2021Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Amit Paul, Arash Elhami Khorasani, Mark Griswold

Patent number: 11056590Abstract: In a general aspect, an integrated circuit (IC) can include a low-voltage region including a low-side driver circuit configured to control a low-side switch of a power converter. The IC can also include a high-voltage region including a floating region of a first conductivity and a high-voltage sensing device disposed in the floating region. The high-voltage sensing device can include a junction-field effect transistor (JFET), and a voltage divider. The voltage divider can include a first terminal coupled to a drain of the JFET, a second terminal coupled to a gate of the JFET, and a sense terminal, the voltage divider being configured to a provide, on the sense terminal. The IC can further include a high-side driver circuit coupled with the sense terminal. The high-side driver circuit can be configured to control a high-side switch of the power converter based on the voltage on the sense terminal.Type: GrantFiled: February 4, 2020Date of Patent: July 6, 2021Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Arash Elhami Khorasani, Mark Griswold, Richard Taylor

Publication number: 20200227403Abstract: The disclosed embodiments include an ESD robust transistor with a compound-SCR protection. The transistor may include a semiconductor substrate having a first conductivity type, a drain region coupled with the semiconductor substrate having a drain SCR component with a first drain region of the first conductivity type and a second drain region of the second conductivity type. The transistor may also include a source coupled with the semiconductor substrate, a channel region of the second conductivity type, and a gate coupled with the channel region having SCR components with a first gate region of the first conductivity type and a second gate region of the second conductivity type. The drain SCR components and the gate SCR components may create a low resistance discharge path along the channel region that activates in response to the ESD such that the ESD discharges through the transistor without causing damage to the transistor.Type: ApplicationFiled: January 11, 2019Publication date: July 16, 2020Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Arash ELHAMI KHORASANI, Mark GRISWOLD
