Publication number: 20160005730Abstract: An ESD protection device is fabricated in a semiconductor substrate that includes a semiconductor layer having a first conductivity type. A first well implantation procedure implants dopant of a second conductivity type in the semiconductor layer to form inner and outer sinker regions. The inner sinker region is configured to establish a common collector region of first and second bipolar transistor devices. A second well implantation procedure implants dopant of the first conductivity type in the semiconductor layer to form respective base regions of the first and second bipolar transistor devices. Conduction of the first bipolar transistor device is triggered by breakdown between the inner sinker region and the base region of the first bipolar transistor device.

Patent number: 9231120Abstract: A Schottky diode includes a device structure having a central portion and a plurality of fingers. Distal portions of the fingers overlie leakage current control (LCC) regions. An LCC region is relatively narrow and deep, terminating in proximity to a buried layer of like polarity. Under reverse bias, depletion regions forming in an active region lying between the buried layer and the LCC regions occupy the entire extent of the active region and thereby provide a carrier depleted wall. An analogous depletion region occurs in the active region residing between any pair of adjacent fingers. If the fingers include latitudinal oriented fingers and longitudinal oriented fingers, depletion region blockades in three different orthogonal orientations may occur. The formation of the LCC regions may include the use of a high dose, low energy phosphorous implant using an LCC implant mask and the isolation structures as an additional hard mask.Type: GrantFiled: June 29, 2012Date of Patent: January 5, 2016Assignee: Freescale Semiconductor, Inc.Inventors: Weize Chen, Xin Lin, Patrice M.

Adaptive scheduling queue control for memory controllers based upon page hit distance determinations
Patent number: 9229885Abstract: Methods and systems are disclosed for adaptive scheduling queue control based upon page hit distance determinations. A threshold occupancy value is determined for a window of previous access requests to a memory and used to adaptively control a number of access requests stored in a scheduling queue buffer. For certain embodiments, a page hit distance (PHD) determination for each access request and historical page hit distance data is used to adjust the threshold occupancy value that determines the number (N) of access requests stored in the buffer prior to removing an access request and using it to access the memory. For each access request, the page hit distance represents the number of previously received access requests since the last access request to access the same page of memory. An average PHD can be determined over a number (M) of previous access requests and used to control the threshold occupancy value.Type: GrantFiled: May 21, 2014Date of Patent: January 5, 2016Assignee: Freescale Semiconductor, Inc.Inventors: Arup Chakraborty, Jaksa Djordjevic -
