Abstract: PURPOSE:To enable die bonding in a stable paste-spread state and the detection of failures by a method wherein, based on image picture information of a surface where paste is spread on an island center and a surface subjected to die- bonding, each of the surface is inspected. CONSTITUTION:A frame(FR) is sent to a die bonding(DB) position by an FR feeder 5. Picture image of the FR is read by an optical system 10; the image signal is subjected to binary processing by an image processing apparatus 11, thereby obtaining the centroid of an island 13 of the FR. Paste 14 is spread on the island by a paste spreading unit 6. The paste 14 is image-sensed by the optical system 10, and a spread state of the paste 14 is estimated by the image processing apparatus 11. When the spread state does not satisfy a reference value, the apparatus 11 issues an alarm. When the state is in an allowable range of the reference value, the die of a wafer is positioned by an intermediate positioning unit 3, and a die 15 is fixed on the center of the island 13. The die 15 is image-sensed by the optical system 10, and the apparatus 11 inspects the state after DB with respect to an image signal. When the reference value is not satisfied, an alarm is issued.

Title: Nonvolatile semiconductor memory
Inventor: SUGIYAMA HISANOBU
IPC: H01L27/115
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous erasure and writing of a memory cell by applying a first positive voltage to a select word line and applying a second voltage not conducting through a memory cell to a nonselect word line at the time of writing a data. SOLUTION: Writing is performed for each word line by injecting charges from all channels into a charge storage layer through FN(Fowler Nordheim) tunneling. A first positive voltage is applied, for example, to a select word line WL2 at the time of writing and a second voltage, e.g. 0V or a low voltage close to 0V, not conducting through a memory cell is applied to nonselect word lines WL1, WL3,..., WLm. Potential of the diffusion layer of a memory cell not pertaining to writing is increased through capacitive coupling between the control gate substrates of these memory cells at the time of writing. According to the arrangement, erroneous writing to nonselect memory cells M21 , M23 ,..., M2n on nonselect word lines WL1, WL3,..., WLm can be prevented at the time of writing.
