Patent number: 10462391Abstract: An inspection system and methods in which analog image data values (charges) captured by an image sensor are binned (combined) before or while being transmitted as output signals on the image sensor's output sensing nodes (floating diffusions), and in which an ADC is controlled to sequentially generate multiple corresponding digital image data values between each reset of the output sensing nodes. According to an output binning method, the image sensor is driven to sequentially transfer multiple charges onto the output sensing nodes between each reset, and the ADC is controlled to convert the incrementally increasing output signal after each charge is transferred onto the output sensing node. According to a multi-sampling method, multiple charges are vertically or horizontally binned (summed/combined) before being transferred onto the output sensing node, and the ADC samples each corresponding output signal multiple times. The output binning and multi-sampling methods may be combined.Type: GrantFiled: July 14, 2016Date of Patent: October 29, 2019Assignee: KLA-Tencor CorporationInventors: Yung-Ho Alex Chuang, David L.

Patent number: 10075662Abstract: A solid-state image pickup device includes a column ADC realizing higher precision and higher-speed conversion. Converters converts a signal of each pixels output via a corresponding vertical read line to a digital value by sequentially executing first to N-th (N: integer of three or larger) conversion stages. In the first to (N?1)th conversion stages, each converter determines a value of upper bits including the most significant bit of a digital value by comparing the voltage at a retention stage with a reference voltage while changing the voltage at a retention node. In the N-th conversion stage, each converter determines a value of remaining bits to the least significant bit by comparing the voltage at the retention node with the reference voltage while continuously changing the voltage at the retention node in a range of the voltage step in the (N?1)th conversion stage or a range exceeding the range.Type: GrantFiled: June 22, 2015Date of Patent: September 11, 2018Assignee: Renesas Electronics CorporationInventors: Shunsuke Kizuna, Katsumi Dosaka, Hiroto Utsunomiya
