Japanese toilet maker Toto Ltd. plans to allocate more than half its total capital expenditure to chip-related operations in coming years, driven by surging demand from semiconductor equipment makers for its specialized ceramics, Bloomberg reported Tuesday.

Toto's Chief Technology Officer Ryosuke Hayashi said spending on semiconductor-related products, which accounted for 11% of capex in the fiscal year ended March, will overtake housing equipment spending as the company completes large-scale expansion in the US and China, the report said.

Toto is allocating about 30 billion Yen ($190 million) to capital spending this fiscal year, ramping up production of its electrostatic chucks used in chip fabrication, the report added.
