A bonding method is provided in which an electronic component is connected via bumps to a substrate and the electronic component is packaged on the substrate. A surface of the substrate that packages the electronic component, a surface of the electronic component that is connected to the substrate, and a surface of the bumps undergo plasma processing. Subsequently, the bumps are heated to a temperature lower than a melting point of the bumps, and the substrate and the electronic component are compression bonded via the bumps.

A distribution server and includes a communicator that communicates with multifunction apparatuses via a network a menu generator that generates menu information based on information obtained by the communicator, the information including display capability information and job capability information for each multifunction apparatus. The menu information includes information for execution of a job and a menu name assigned for the job. A data memory stores the generated menu information and a distributor retrieves, from the data memory, menu information requested by the multifunction apparatus and distributes, via the network, the menu information to the requesting multifunction apparatus.

An error correction code of (N+M) words is configured by adding an ECC parity of M word (M is a natural number) to N words extracted at an interval of A words with respect to data of (A*N) words (A and N are natural numbers) inputted via an interface. A data distributor distributes (N+M) words to the respective (N+M) physical blocks to record by A words. In a case where a writing error has occurred, data recorded in a cell sharing page of the page and in a page of another physical block configuring the error correction code is read. A disappearing correction is carried out to the data of the cell sharing page by using the data, and thus the data of the cell sharing page is recovered and written. In this manner, in the multi-level nonvolatile memory, an error in writing of a certain page can be prevented from propagating to a written page sharing a cell.

A semiconductor recording apparatus includes a logical-to-physical conversion table 115 showing correspondence between a physical address of said semiconductor memory and a logical address and writes the table to a flash memory 120. On receiving a write command issued from a host device 200, a block management section 114 selects a physical block with reference to said logical-to-physical conversion table, and updates said logical-to-physical conversion table. A logical-to-physical conversion table initializing section 117 updates a physical address corresponding to each logical address of the logical-to-physical conversion table into an invalid address. Accordingly the apparatus can render the number of rewrites of physical blocks uniform irrespective of writing conditions.

A memory card controller for controlling data transfer between a host device that requests data transfer by issuing a command specifying a data amount and a memory card that executes a transfer operation from receipt of a transfer start instruction until receipt of a transfer end instruction. The memory card controller is provided with a clock start/end control unit 10 that suspends supply of a clock signal to the memory card when a data amount transferred from the memory card as a result of the transfer operation reaches a data amount specified by an nth command received from the host device, and resumes supply of the clock signal to the memory card if a subsequent command received with supply of the clock signal to the SD card in a suspended state specifies an address consecutive to an end address of data transfer requested by the nth command as a start address.

A host device 200A includes a data buffer 250. When data has been already written to a part of a physical block and data is additionally written to the physical block, it is determined whether or not the data written to the physical block is held in the data buffer. When the data is held, data is written to the block, and when an error exists, data in unit of physical blocks is rewritten. When the data is not held in the data buffer, a new physical block is required to be secured and then, data is written to the new block. Thereby, even when power is shut off or an error occurs during writing in the semiconductor memory device, destruction of data already written is prevented.

An error correction code of (N+M) words is configured by adding an ECC parity of M word (M is a natural number) to N words extracted at an interval of A words with respect to data of (A*N) words (A and N are natural numbers) inputted via an interface 1. A data distributor 3 distributes (N+M) words to the respective (N+M) physical blocks to record by A words. In a case where a writing error has occurred, data recorded in a cell sharing page of the page and in a page of another physical block configuring the error correction code is read. A disappearing correction is carried out to the data of the cell sharing page by using the data, and thus the data of the cell sharing page is recovered and written. In this manner, in the multi-level nonvolatile memory, an error in writing of a certain page can be prevented from propagating to a written page sharing a cell.

An electrode-built-in susceptor comprises a mounting plate and a supporting plate which are made of an aluminium-nitride-group-sintered member, an inner electrode which is made of a conductive aluminium-nitride-tantalum-nitride-composite-sintered-member or a conductive aluminium-nitride-tungsten-composite-sintered-member so as to be formed between the mounting plate and the supporting plate, power supplying terminals 16, 16 which is disposed in fixing holes 13, 13 which are formed on the supporting plate so as to be attached to the inner electrode. The power supplying terminals are made of a conductive aluminium-nitride-tantalum-nitride-composite-sintered-member.By doing this, it is possible to provide an electrode-built-in susceptor which has superior durability under a high temperature oxidizing atmosphere condition and a method for manufacturing an electrode-built-in susceptor with a high product yield and a low production cost.
