摘要:
In a formation method for forming a fine structure in a workpiece (30) containing an etching control component, using an isotropic etching process, a mask (32, 34) having an opening (36) is applied to the workpiece, and the workpiece is etched with an etching solution (38) to thereby form a recess (40), corresponding to a shape of the opening, in a surface of the workpiece. The etching of the workpiece is stopped due to the etching control component eluted out of the workpiece in the etching solution within the recess during the isotropic etching process.

摘要:
An LCD device in an LCD projector includes a TFT substrate, a counter substrate, an LC layer sandwiched between the TFT substrate and the counter substrate, and a pair of compensation substrates attached onto the outer surfaces of the TFT substrate and the counter substrate far from the LC layer. The compensation substrate has a negative coefficient of thermal expansion (CTE) for compensating the retardation caused by a temperature rise of the TFT substrate and the counter substrate due to irradiation thereof by a light source.

A method for manufacturing a semiconductor device includes cutting a resin sealing body into a plurality of pieces. The resin sealing body includes a plurality of semiconductor chips mounted on a wiring board, a heat spreader disposed above the plurality of the semiconductor chips, and sealing resin filled between the wiring board and the heat spreader. The cutting the resin sealing body includes shaving the resin sealing body from a side of the heat spreader and shaving the resin sealing body from a side of the wiring board. The method prevents the heat spreader from generation of burrs.
