PROBLEM TO BE SOLVED: To provide a surface processing method which can prevent external or internal interference to a chip device, and a chip device produced by the method. SOLUTION: A surface processing method for a chip device comprises a step (a) of providing a chip body having at least one exposed surface, a step (b) of applying a polymeric monomer solution having a flexible fragment fluorocarbon polymer end and a silane-group polarized end to the at least one surface of the chip body, and a step (c) of curing the polymeric monomer solution under appropriate environment settings to remove all solvents and to polymerize the polymeric monomers for forming a polymeric material layer 20 on the at least one surface. One exposed surface of the polymeric material layer 20 thus has the properties of the flexible fragment fluorocarbon polymer, thereby protecting the chip body from any external or internal interference.

PROBLEM TO BE SOLVED: To provide a memory storage device having a fingerprint sensor, and a method for protecting data stored therein. SOLUTION: The memory storage device comprises a host interface connected to a terminal host, a controller connected to the host interface, a fingerprint sensor connected to the controller, and a memory module. The controller communicates with the terminal host by handshaking and downloads an appropriate driver and an appropriate application program suitable for the terminal host from the memory module to the terminal host. The terminal host receives an instruction from a user through the two downloaded programs, and advises the controller to control the fingerprint sensor so as to read user fingerprint data in recognition queue. Utilizing the application program, the terminal host processes the fingerprint data in recognition queue, compares the data with template fingerprint data stored in the memory module, and determines whether or not the two data match. In accordance with the matching result, the terminal host is allowed to access a specific block of the memory module. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract:
PROBLEM TO BE SOLVED: To save electric power consumption of an image check sensor chip, miniaturize it, and reduce its cost. SOLUTION: In this image matching function-equipped slide type image sensor chip, a rectangular array sensor senses a finger sliding and passing through on it and obtains a fingerprint fragment analog signal, which is converted into an amplification signal by a gain adjustable amplifier. An analog/digital converter converts the amplification signal into a digital fingerprint fragment signal based on the sequence. An image matching module receives and processes two arbitrary adjacent digital fingerprint fragment signals continuously based on the sequence and outputs a plurality of fingerprint fragment images which are not continuously and mutually overlapped by input/output interface one by one. A control logic controls all the functional zone operation and connection. A terminal unit system receives the fingerprint fragment image and synthesizes one complete fingerprint image by stacking another side on a side of the fingerprint fragment image together by a block building method.
