An SiGe layer is grown on a silicon substrate. The SiGe layer or the silicon substrate and SiGe layer are porosified by anodizing the SiGe layer to form a strain inducing porous layer or a porous silicon layer and strain inducing porous layer. An SiGe layer and strained silicon layer are formed on the resultant structure. The SiGe layer in the stacking growth step only needs to be on the uppermost surface of the porous layer. For this reason, an SiGe layer with a low defect density and high concentration can be formed. Since the SiGe layer on the strain inducing porous layer can achieve a low defect density without lattice mismatching. Hence, a high-quality semiconductor substrate having a high strained silicon layer can be obtained.

A method of manufacturing a semiconductor substrate includes a growing step of growing a second single crystalline semiconductor on a first single crystalline semiconductor, a blocking layer forming step of forming a blocking layer on the second single crystalline semiconductor, and a relaxing step of generating crystal defects at a portion deeper than the blocking layer to relax a stress acting on the second single crystalline semiconductor. The blocking layer includes, e.g., a porous layer, and prevents the crystal defects at the portion deeper than the blocking layer from propagating to the surface of the second single crystalline semiconductor.

A method for generating mask pattern data of a photomask used to form microlenses divides a pattern formation surface of a mask pattern to be used for the photomask into a plurality of grid cells, acquires data which represents transmitted light distribution of the mask pattern to be used for the photomask, determines whether to place a shield on each of the plurality of grid cells by binarizing the plurality of grid cells in order of increasing or decreasing distance from a center of the pattern formation surface using an error diffusion method to acquire the transmitted light distribution, and generates mask pattern data which represents an arrangement of the shields based on results from the determining step.

This invention provides an SOI substrate manufacturing method using a transfer method (bonding and separation). A separation layer (12) is formed on a silicon substrate (11). A silicon layer (13), SiGe layer (14), silicon layer (15′), and insulating layer (21) are sequentially formed on the resultant structure to prepare a first substrate (10′). This first substrate (10′) is bonded to a second substrate (30). The bonded substrate stack is separated into two parts at the separation layer (12). Next, Ge in the SiGe layer (14) is diffused into the silicon layer (13) by hydrogen annealing. With this process, a strained SOI substrate having the SiGe layer on the insulating layer (21) and a strained silicon layer on the SiGe layer is obtained.

An output apparatus for forming output information on the basis of input information inputted from an external apparatus and outputting is constructed by a connector for connecting the output apparatus to the external apparatus so that they can communicate, a memory to store a data group to manage a menu structure for setting an output environment, an internal environment setting unit for setting an output environment on the basis of the data group, a transfer unit for transferring the data group from the memory to the external apparatus through the connector, and an external environment setting unit for setting an output environment onto the external apparatus on the basis of the data group transferred to the external apparatus. An operating method for the internal environment setting unit and an operating method for the external environment setting unit are identical.
