25 Aug 1997TL;DR: In this article, a semiconductor device coupled to a ball grid array substrate is encapsulated by an optically transmissive material (OTM) and solder balls are formed on the solder pads.
Abstract: A semiconductor device (10) coupled to ball grid array substrate (11) and encapsulated by an optically transmissive material (29, 31). The ball grid array substrate (11) has conductive interconnects (14) and a semiconductor receiving area (17) on a top surface and solder pads (13) on a bottom surface. An optoelectronic component (24) is mounted on the semiconductor receiving area (17) and encapsulated with the optically transmissive material (29, 31). Solder balls (18) are formed on the solder pads (13).

22 Dec 2008TL;DR: In this paper, the power management in a light emitting diode (LED) system with a plurality of LED strings is discussed, and a feedback mechanism is implemented to monitor the tail voltages of the active LED strings to identify the minimum tail voltage and adjust the output voltage of the voltage source based on the lowest tail voltage.
Abstract: Power management in a light emitting diode (LED) system having a plurality of LED strings is disclosed. A voltage source provides an output voltage to drive a plurality of LED strings. An LED driver implements a feedback mechanism to monitor the tail voltages of the active LED strings to identify the minimum tail voltage and adjust the output voltage of the voltage source based on the lowest tail voltage. A loop calibration module of the LED driver calibrates the feedback mechanism of the LED driver based on a relationship between a digital code value used to generate a particular output voltage and another digital code value generated based on the minimum tail voltage resulting from the particular output voltage.

05 Aug 1994TL;DR: In this article, selective isotropic etch procedure is used to laterally recess the sidewall of the conductive layer (18) and a sidewall spacer is formed adjacent to the seam opening of conductive layers (24 and 14).
Abstract: An interconnect structure is formed having a substrate (10). A conductive layer (14) is formed overlying the substrate (10). A conductive layer (18) is formed overlying the conductive layer (14). An opening (19) is etched through the conductive layer (18), exposing a top portion of conductive layer (14), and forming a sidewall of the conductive layer (18). An selective isotropic etch procedure is used to laterally recess the sidewall of the conductive layer (18). A sidewall spacer (22) is formed adjacent the sidewall of the conductive layer (18). A conductive layer (24) is formed within opening (19) and adjacent the spacer (22) to form an interconnection between conductive layers (24 and 14). The interconnection is self-aligned, and conductive layer (18) is reliably isolated from the interconnect due to the lateral recessed sidewall of the conductive layer (18).

28 Mar 1994TL;DR: In this article, a ferromagnetic memory circuit with a control electrode (50) is formed to control current flow between the first and second current electrodes (44 and 46), and a sense conductor is used to externally provide the logic value stored in the device.
Abstract: A ferromagnetic memory circuit (10) and a ferromagnetic memory device (15) which has a substrate (42). Within the substrate (42), a first current electrode (44) and a second current electrode (46) are formed. A control electrode (50) is formed to control current flow between the first and second current electrodes (44 and 46). A ferromagnetic region (68) is used to store a logic value via magnetic flux. Two conductive layers (62 and 70) and a conductive spacer (78) form a sense conductor for device (15). The sense conductor is used to externally provide the logic value stored in the device (15). A conductive layer (82) forms a program/erase line for altering the logic value stored in the device (15). A logic one or a logic zero is stored in ferromagnetic region (68) depending upon a direction and a magnitude of current flow through conductive layer (82).
