It is an object of the present invention to provide an adhesive film which is used for producing, by a laminating method, a flexible metal-clad laminate in which the change in dimensions is suppressed, a flexible metal-clad laminate including the adhesive film, and a production method therefor. The present invention relates to an adhesive film including a polyimide film and an adhesive layer containing a thermoplastic polyimide, the adhesive layer being disposed on at least one surface of the polyimide film, a flexible metal-clad laminate produced by laminating a metal foil to the adhesive film with a thermal roll laminator, and a production method therefor, wherein the polyimide film is formed by a process including step (A) of mixing a polyamic acid solution, a dehydrating agent, and an imidization catalyst, and casting and applying the mixture onto a support to form a gel film; step (B) of stripping off the gel film and fixing both ends of the gel film; and step (C) of heating and transporting the film with both ends being fixed in a state loosened in the TD direction.

It is an object of the present invention to provide a method for producing a flexible laminate in which the appearance and dimensional stability after removal of metal foils are improved. The present invention provides a method for producing a flexible laminate 5 including a heat-resistant adhesive film 3 and a metal foil 2 bonded to at least one surface of the heat-resistant adhesive film 3. The method includes a step of performing thermal lamination by passing the heat-resistant adhesive film 3 and the metal foil 2 between a pair of metal rolls 4 through a protective film 1, and a step of separating the protective film 1. The molecular orientation ratio of the protective film 1 is in a range of 1.0 to 1.7.

For high density packaging of a semiconductor device, the semiconductor device has a multi-layer substrate, a first-stage chip connected electrically to the multi-layer substrate, other package substrates stacked in three stages on the multi-layer substrate and each connected to an underlying wiring substrate through solder balls, second-, third- and fourth-stage chips electrically connected respectively to the other package substrates, and solder balls provided on the bottom multi-layer substrate. The number of wiring layers in the bottom multi-layer substrate which has a logic chip is larger than that in the package substrates which have memory chips, whereby the semiconductor device can have a wiring layer not used for distribution of wires to the solder balls and wiring lines in the wiring layer can be used for the mounting of another semiconductor element or a passive component to attain high density packaging of the semiconductor device as a stacked type package.

The present invention provides a plate-like protect member at a front surface of an ink jet printer head having an orifice which is capable of jetting ink. The protect member provides a step around the orifice having an outer portion higher than an inner portion. The protect member also provides an ink repellency layer on an outer portion of the step. Thus, the ink jet printer head of the present invention can prevent the jetted ink from the orifice to creep up toward back of the ink jet printer head which is reverse direction to the ink jetting direction.
摘要:
A semiconductor file system features a first nonvolatile memory electrically erasable, a second nonvolatile memory not electrically erasable, a volatile memory, a controller, and a control section which controls the controller wherein a physical address corresponding to a logical address specified from an external system is accessed. The first nonvolatile memory stores data for the external system to perform operations, first management information indicating correspondence between physical and logical addresses, and second management information indicating a state of the first nonvolatile memory. The second nonvolatile memory previously stores interface information. The controller determines a physical sector address. The control section is for controlling input/output of data from/to the external system and for temporarily storing write data into the first nonvolatile memory from the external system in the volatile memory and then transferring the write data from the volatile memory to the first nonvolatile memory.
摘要:
A control method and system when a flash memory is used as a semiconductor disk or a main memory in an information processing system. A semiconductor file system comprises a first nonvolatile memory electrically erasable, a second nonvolatile memory not electrically erasable, a volatile memory, a controller which controls the memories, and a control section which controls the controller wherein a physical address corresponding to a logical address specified from an external system is accessed. The first nonvolatile memory stores data for the external system to perform operations, first management information indicating the correspondence between physical addresses at which the data is stored and logical addresses, and second management information indicating a state of the first nonvolatile memory. The second nonvolatile memory previously stores interface information required for inputting and outputting the data from and to the external system and read-only data of the data. The controller has a control means for determining a physical sector address forming predetermined high-order bits of the physical address when data is output from the first nonvolatile memory or when data is input to the volatile memory, means for storing the determined physical sector address, and means for consecutively generating addresses in a sector determined by the physical sector address.
